An Odd Couple For The Iris Family.

Another grey week and another plant hunt for something special. Usually I have a list of plants in mind but right now it is hard because some of the plants I wanted to do were damaged by an unusually hard freeze which came in early November last year. At that time many of the plants were not hardened off for the winter with the damage especially seen by broad-leaved evergreens which have much browned and dead foliage now. In my wandering last week I stumbled upon two plants of the same family which are stars at this time of the year. They are the Algerian Iris (Iris unguicularis) and the Stinking or Gladwyn Iris (Iris foetidissima). They are the stars for different reasons as you will see!

Winter or Algerian Iris (Iris unguicularis) is sometimes incorrectly labeled by its old name of Iris stylosa.

The first stop we make is with the Algerian or Winter Iris with its lovely large violet blooms. It was first described by Botanist/clergyman  Jean Louis Marie Pioret (1755-1834) in his journal ‘Voyage et Barbarie’ in 1789.  He had been sent to Algeria by Louis XVI between 1785-6 to study the flora. The lovely Iris is more widespread and found in area from Algeria and Tunisia across north Africa into Turkey, Greece Crete and Malta. In the vast area it is known to live int there is some variation in color and form.

The type of Iris unguicularis I have found in Victoria seems to be the 'Algerian' form which has the largest flowers of the species.

Algerian Iris produce new leaves in late spring and through the summer. Often you can clip the old leave edges back when they get looking tattered. Iris unguicularis likes the sunniest, driest spot in the garden with the grittiest soil. At Government House in Victoria the plants are perfectly place in the terrace garden which is on a southern exposed rock-face.  The warmer and drier the summer the more blossoms will be produced.  One thing about these plants is they hate to be moved or have their roots disturbed in any way.

A just opened Algerian Iris in the late afternoon sun has delicate coloring and scent.

The Gladwyn Iris is from more northern areas from southern England, Ireland through Portugal, Spain Canary Island on to Italy and finally the island of Malta.

The Gladwyn Iris (Iris foetidissma) is more famous for its brightly colored seeds which are seen during the winter months here.

The ‘Stinking Iris has gained an unfair reputation from its name. One has to crush the leaves and the flower to obtain even a faintly unpleasant scent. Iris foetidissima is a plant which has long been with us. It blooms in the traditional Iris time of late May and June, but, the flowers are small and often hidden in the foliage. The colors range from a creamy ochre into plummy shades.

The flowers of Iris foetidissima are often hidden in the plants foliage.

The Gladwyn Iris is a plant of the woodlands, hedgerows, scrubs and cliff edges and other rocky sites. It is a plant which likes chalky and limestone  heavy locations. Gladwyn Iris can grow in the sun or dappled shade and like average soil. They like sufficient water when they are growing in the spring and then dry conditions the rest of the year.After blooming it produces larger than average seed pods which ripen through the summer and into early winter when they burst. Inside the pods are usually bright orange seeds which remain colorful throughout the winter. The other day I noticed pods recently opened and others still green and waiting to split. Just like the flowers there are other known seed colors which are sought after and they range from golden yellows to creams and white. Probably the most want of the Gladwyn Iris is Iris foetidissima ‘Variegata’ with beautifully uniform cream stripes running up the leaves.

The Variegated Gladwyn Iris (Iris foetidissma 'Variegata') is most sought after, as you see they are stunning in dappled location at Glendale Garden.

Algerian and Gladwyn Iris are about the same height 45-60cm.(12-18 in.) and width They also share the same temperature tolerance to 15 c. (5 f.) or zones 7 through 9. Both plants are drought tolerant when they have been established. They are rabbit and deer resistant but can be damaged by slugs and snails. They make excellent specimens, accents s, mass evergreen plantings and work well in containers. Both of these species are not easy to find in plant centres or garden shops, the best bet would be to find them at garden sales or from specialty Iris growers.

It Was A Dark and Stormy Night….

It was a dark and stormy night and the wind was blowing through the trees in the cemetery as I trudged past. I shivered and pulled my coat collar up to protect me from the chill. As I walked along, the shadows moved and I shuddered as I passed the dark eerie Common Yew (Taxus baccata) trees because I knew that these trees were always sacred to the Druids. It was one of the five great trees that stood in their sacred sites.

A Taxus baccata as you might find it in the wild which is found at St Ann's Academy.

Taxus baccata is native to Ireland, England , through Europe down into the northern tip of Africa and over to West Asia. It is in northern Europe where Common Yew has been a significant tree associated with various early religions and cults. In Norse mythology we meet the Yggdrasil ‘the world tree’. Yggdrasill means Yew (support)pillar leading some theorists to believe this tree is a Yew instead of the traditional Ash(Fraxinus species) Yew are also connected with the ‘Fairy races’ of Ireland and Wales. Many tales connect these trees to fairy rings, mysterious appearances and disappearances.

Yew trees in ancient times were placed in sacred sites which later often became cemeteries and church yards.

 

We are most familiar with Common Yews being associated with Druid culture found in Ireland and Wales, during the Iron Age Celtic period. During that time the wood was turned into many symbolic and spiritual articles such as wands, and staffs. The wood was also used for divination purposes and at festivals. In the 19^th century a cup made of Yew wood was found near a village in North Wales, this item was likely used in Druidic ceremonies.

The wood of Taxus baccata is very flexible and was traditionally used for making the deadly longbow of Medieval times.

 

Other places were the Druidic religion likely touches the Common Yew is in their prominent placement in some of the oldest churchyards in Great Britain, Often churches were placed in known sacred places of Druid and other non Cristian groups to help suppress them and usurp the site and ideas related to it. One of the oldest known Taxus baccata is found in a churchyard in North Wales, it is over 4000 years old.

Taxus baccata with its dark color and fine needles is often clipped when seen in a garden setting.

 

Throughout history the wood of Common Yew has been associated with deadly things. The needles and the flesh of the seeds(arils) is highly poisonous and many people and livestock have died from it. The wood was much used before the use of iron became widespread. It is very hard and resists the effects of water very well. Yew is a tree of death, used for making longbows, coffins, weapon handles and arrow shafts and disturbingly bleeds red sap. The worlds oldest implement, a spearhead is thought to be 50,000 years old and made out of Taxus baccata wood,The famous longbows of the Welsh were made out of Yew and were first recorded in use in 633. More recently it is used for furniture, tool handles and veneer. The wood is golden smooth with a wavy grain.

All Taxus species contain deadly alkaloids in all their parts except in the brightly colored arils which cover the seeds.

 

Taxus baccata has a long association with gardens, official and unofficial because they are easily grown and adaptable to many situations. At many large government buildings this tree is used in one of the most traditional ways, as a clipped hedge in the form of Taxus baccata ‘Fastigiata’ or Irish Yew. Taxus baccata ‘Fastigiata’  is the form which we come across most often in Victoria as it is narrower in form.

Taxus baccata 'Fastigiata' is used at the corners of the Hardy Fuchsia Garden at Glendale Gardens.

If you want to grow some Common Yew trees, there are somethings to keep in mind. Plants are male or female, with the females having the red berries. Yews can grow in almost complete shade to full sun but seem to be best with more light than less. They are slower growing than most shrubs and are more expensive because of this. Over many years they can attain heights in excess of 20m(65ft) and can live several thousand years. They like a good soil which nutrient rich, stay away from clay if possible.

A golden Taxus baccata 'Fastigiata Aueromarginata' is seen above a common Yew here at one of the entrances to Hampton Park.

 

Taxus baccata are fairly drought tolerant and withstand air pollution making them an ideal city plant. They are rated as zone 6 meaning they can withstand -20c(-10f) although they might get some wind burn damage on their foliage.If making a hedge space them 40-45cm apart and pinch them back at the time of planting to make them bushy. Remember that this will be a slow-growing hedge. You may want to use one of the narrower forms.

The Yew hedge seen here is carefully clipped to maintain its shape and condition.

There are several hundred named varieties which have to propagated by cuttings. Most forms are female and may produce seeds. Look for especially narrow forms such as the dark green ‘Fastigiata’ or golden ‘Fastigiata Aueromarginata’ or the female golden form ‘Standishii’ .Taxus baccata ‘Repandens’ has low spreading branches and ‘Cavendishii’ has wide-spreading branches that droop at the tips.

This Taxus baccata tree grows in almost complete shade during most of the year yet is very healthy.

The Scarlet Letter Q or is it O.

Big winds are starting early this year, the forecast is for a colder winter here. I n=know our winters are nothing like those from the rest of Canada and much of North America, we are wet and very slippery with ice here if it gets cold. With cold weather comes more brilliant colors in the departing leaves which are on the trees. So here we are in the blustery weather wanting to go and walk in the forests and big parks to see bright colors. Some of the best color comes from the Quercus family and without a doubt the absolute star in the family is Scarlet Oak (Quercus coccinea). All I can say is Blaze on and warm us up with your firey flame-like leaves!

The Scarlet Oaks enliven the Stelly's Secondary School campus in the autumn.

Scarlet Oaks are one of the trees which people think of when they want to experience the colors of autumn in eastern North America. The colors are so fine that many people take tours through the northern United States and eastern Canadian provinces to experience it. I have never been myself but can imagine how breath-taking it must be based on the color of the same trees here.

As the leaves of Quercus coccinea breakdown anthocyanins are released giving the leaves their red coloring.

Part of the reason of the strong bright colors in Quercus coccinea has to do with how the leaves break down in the fall. The component which affects color is anthocyanin( giving reds and blues) which is stored in the natural sugars found in the leaves. As the leaves start to break down in the fall the anthocyanins are released and their red and blue tones effect the color of the leaf. Many leaves of other trees change into yellow and orange tones which are caused by xanthophyll and carotenoids.It is surprising we get such good color because we are not that cold in the autumn here.

The Scarlet coloring of Quercus coccinea is very intense and brilliant.

Scarlet Oaks are widespread in the east growing from Maine to Alabama and east into Oklahoma. It is a tree which tolerates a fairly wide range of conditions but often is seen growing in upland forests, ridges and hillside where the conditions are a bit drier and the soil is often is sandy and gritty. These are trees of the upper canopy and do not like to be in the shade.

This Scarlet Oak is one of many Oaks found in the 'Mayors Grove' at Beacon Hill Park in Victoria.

Quercus coccinea grow to be large trees of up to 24m(80ft). When they are young they have a more pyramidal shape and with age get a more rounded shape.  The leaves are deeply lobed which gives this tree a more lacey feeling  and more delicate look compared to others of the species. The tree here which might be mistaken for Scarlet Oak is the Pin Oak (Quercus palustris), it needs a damper site and is more likely to be seen up island or in the Vancouver area which have more rain compared to the drought here.

These young Scarlet Oaks show their pyramidal shape which will change with age.

Scarlet Oaks are considered to be the best of the species to grow because of their adaptability to soils and water, their brilliant color and their tolerance of urban conditions.  They like an average to sandy soil which is on the acidic side to keep them from getting chlorosis. They are naturally from drier sites but tolerate damper sites as long that there is good drainage. These trees require full sun to perform their best. These trees are popular with landscapers and are often seen in industrial and commercial settings, here they are seen around parking lots and in parks. These trees have attractive foliage and bark.

 

The bark of Scarlet Oak is ridged and an overall grey color.

 

The acorns of Scarlet Oaks can be hard to come by here with the Squirrels  which eat store them. They are 1-2.5cm(1/2-1in.) long with their cap covering half the nut from the top. Acorns are produced in large quantity every 3 to 4 years. Propagation is by seed which has to be collected before the squirrels get the best ones. Check  your harvest in a bucket of water and throw away any that float. The seed has a short period of viability and needs to be sown as soon as possible.

 

Broadmead Village Shopping Centre has some of the best Scarlet Oaks and other autumn color in the Victoria area.

 

 

Scarlet Oaks are rated at zones 4 through 9 and take -35c(-30f). If you have a large property this tree is an excellent choice for you as it makes an easy to maintain tree which need little work. It is best to buy these trees in a container as like other Oaks they have a tap-root which is easily damaged.

Bright, Rosy Twinkles in the Garden.

This week it has taken a turn for fall the sun shines and the nights are much cooler. Finally there are touches of color developing in the leaves of trees, in the next few weeks the show of yellow, red and orange will be at their peak here. Gardeners are starting to remove spent annuals and cut down yellowing and bedraggled perennials. Some grasses such as Miscanthus are blooming while others are finnished waitng for the winter rains. Several plants are blooming as it is coming into thier summer, these are some of the bulbs from South Africa. One of the most showy is Nerine bowdenii (Guernsey Lily) and how beautiful it is.

The pink coloring of Nerine bowdenii makes it a favorite flower amoung many who grow it.

Nerines are all found in Africa with 23 0f the species found in South Africa. There is some confusion as to exactly how many species there ranging between 25 and 30. We do know the plant Nerine is named for the Greek word ‘Nereis’ for sea nymph. Bowdenii comes from Athelstan Hall Cornish Bowden (1871-1942) who was born in Devon and went on to become the Government Land Surveyor of the Cape Colony which later became South Africa. In 1903 he brought his namesake plant back to England.

The strap-like foliage of these Nerine bowdenii bulbs is blended in with Acorus leaves.

Nerine bowdenii is considered to be the most hardy of the known Nerine species. This is because it was originally found high(3000m or nearly 10000 ft.) in the  Drakensburg Mountains in north Natal. There it flowers in February to May. It is often found growing in cracks of  the stony cliffs and where a little soil and leaf mold has accumulated over time.

Nerine bowdenii is perfectly planted in the stony outcropping of the 'Terrace Gardens' at Government House in Victoria.

Many South African plants are relatively new to gardening and have been thought to be more tender than they have turned out to be. Here in Victoria and in the southern corner of British Columbia we have a very similar climate to parts of South Africa and have been lucky to enjoy a wide range of interesting plants which grow there.  We have a mild winter which is damp and warm to hot summers with a prolonged drought which is perfect for many bulbs such as Nerine bowdenii.

This clump of Nerine bowdenii is in the dappled shade at Finnerty Gardens.

Nerine bowdenii is a fairly easy and adaptable plant to grow. Plant the bulbs close together with part of the bulb exposed like it is found in the wild. Grow it in any rich soil with good drainage so the bulbs do not sit it overly wet soil for long periods. When planting bulbs it is a good idea to add some bone meal for development of strong healthy roots. It is said that this species of Nerine can take -10(14f) temperatures easily. If you live in a colder climate grow your plants in a container which you may choose to sink into the ground and lift late in the fall to over-winter inside.

The typical Nerine bowdenii floral scape has up to a dozen flowers which are usually in a pink shade.

Several named selects can be found of Nerine bowdenii which are in pink shades as well as a white form. This plant is about 60cm(2ft) tall and has proved to be an excellent long lasting cut flower. The strap-like foliage is similar to that of Agapanthus and is an attractive mid green color. Propagation is by division of the bulbs or planting the fleshy seeds as soon as they become ripe. From seed to blooming bulb takes up to 6 years.

The bright pink Nerine bowdenii flowers against the maroon shades of this foliage is quite spectacular.

We Should Be Grateful for Frikarts Aster.

So we are finally starting to have cooler nights. The last week was more rain than sun. Some trees are starting to color up and the sour tang of decay is beginning to creep into the air. There are a few plants which are in their glory now this late in flowering year. One group which stands out are Asters, their lavender blues are seen along roadsides and in gardens everywhere. Aster x frikartii ‘Monch’ (Monch Aster or Frikart’s Aster)is arguably the best of this mighty group of plants.

Aster x frikartii 'Monch' combines the best of its parents to create a wonderful plant.

Frikart’s Aster was a planned meeting of 2 species to produces a plant that combined the best of the parents.  We do not know exactly why these plants were selected by Carl Ludwig Frikart (1879-1964) but we are grateful for the outcome. Little is known about Frikart other than he ran a nursery in Stafa, Switzerland and is said to have had a large rock garden which was built in the 1930s.

This clump of long lived Aster Frikartii 'Monch' is found in Playfair Park.

The two Asters Frikart decided to combine were Aster amellus and thompsonii.  Aster amellus is called Michealmas Daisy or Starwort in Europe where in comes from. It grows from France east through Italy into Czechoslovakia. It has more attractive leaves than most other Aster species and is more tolerant of dry conditions than most others. It also less effected by most of the common disease of Asters such as leaf spot and mildews. The other Aster selected was Aster thompsonii which comes from the Himalayas and is most commonly seen here as the form ‘Nana’ It has larger lavender blue flowers and wiry dark stems. I have grown both species and must say that they both are neat attractive plants with less pests or disease than other better known species.

The single flowers of Aster Frikartii 'Monch' make beautiful subjects for use in boquets.

Carl Ludwig Frikart began crossing amellus and thompsonii and named his first successful crosses after the famous mountains in his native Switzerland. Three were named in 1918: Eiger, Jung Frau and Monch, of these ‘Monch’ became the most famous and planted throughout the world. He continued making crosses and later released ‘Wunder von Stafa’ (‘Wonder of Stafa’) named after the town were he lived, it is still grown and is available especially in Europe. Later Alan Bloom of Bressingham Nursery would add the cross ‘King George’ to the list.

'Monch' Aster fits well in this mixed perennial and shrub planting at Government House.

Monch Aster is in many ways really well suited for the garden where other Asters are not. Many of the Aster we grow originally come from plants which grow in swampy areas or on the edges of waterside. Aster x frikartii Monch‘s parents come from naturally dry areas. Here we have damp springs and bone dry summers which cause many Asters to develop diseases which are rarely seen with Monch’s Aster

.

The simplicity, large size and purity of color of Monch Aster flowers is one of most pleasing aspects of the plant.

Monch Aster are easy to grow, they like full sun, well drain soil with some nutrients and less than average water throughout the year. They are fairly compact especially in full sun, growing 60-90cm(2-3ft) tall and with about 50cm(1.5ft). If they are tending to flop stake them up, I have not really seen this here unless the plants are in to much shade.  They are hardy to zone 6 or -15c(5f).

The attractive foliage that Aster x frikartii `Monch`is an added benefit.

Probably the best reason to use this plant is its extremely long season of bloom which lasts from late July into October.  Here you will see it in traffic medians in Saanich because its a low maintenance plant which gives color for several months. Frikart`s Aster is very versatile, it can be used in many places. It is seen in sunny perennial and shrub borders, as seasonal color, in containers, mass planted, in dry borders or hard to water areas and as an accent in gardens.

Heavenly in the Garden.

Back to school, those are dreaded words for some, a relief for others and the beginning of a new chapter in life for many more. I must admit I did not like grade school. It was not until later when I had a break from the grind of it, had more perspective and experience in life that I enjoyed it more. Now I think about i more fondly look back at my time in school especially the time I was in Hort. school learning so many new things which I use all the time now. Learning the plants back then was more of a challenge, now it is adverture which takes me across the world and back in time. I first saw Nandina domestica (Heavenly Bamboo or Sacred Bamboo) at Van Duesen Gardens and over the years have always loved it’s simple elegant beauty.

Heavenly Bamboo is a triple treat with wonderful foliage, flowers and bright red berries which appear in the fall.

Nandina domestica is a plant which comes to us from Asia, there it is found in central Northern India, China and Japan. In Japan it is known as Nantzen (meaning southern sky) is derived from the chinese name(southern heaven)and our latin name is from it.  Nandina is strongly connected with the new year in both China and Japan, in China it is associated with the kitchen god Zhao Jun(Zhen) who is the most important domestic god and protects the hearth and family.

The light delicate foliage and compact habit makes Heavenly Bamboo very popular here.

In Japan it is especially popular and is often seen at the entrances of houses and is  also used during the holiday season of late December and January. Here it seen in traditional Kadumatsu decorations which are placed in pairs at the front door of  the home. It is also in Japan where Carl Peter Thunberg(1743-1828) first documented Nandina domestica while he was there in 1775-76. His name is one of the most important associated with botanical plants in Japan and he named many of the best known ones of today.

A good crop of berries is seen with this planting of Nandina domestica at U.B.C. Botanical Gardens in Vancouver.

Heavenly Bamboo was introduced to the gardening public in 1804. Also back in Japan at that time there were new forms being discovered and it was becoming popular there as a bonsai subject.Some of the new forms had narrower leaves and lent themselves to Bonsai. By the late 1800s’ nearly 200 cultivars had been named and catalogued there. Sadly many of these forms have been lost although recently many new color forms have been selected by growers in Europe and North America.

Nandina domestica is often mass planted or used as informal hedging here.

Here we have come to love Heavenly Bamboo for its versatility, beauty and color throughout the year. It tolerates any type of soil as long as it is well-drained. It is not fussy about light and can take the full sun to full shade although it is best with some protection from harsh midday sun in the summer especially in drier and more southern areas that here. Nandina domestica is tolerant of fairly dry areas as long as it is sheltered from drying winds like most other evergreens. This plant grows by producing suckers from the base, this over time will produce a dense clump. Pruning can be done to remove damaged parts and to thin it out if it gets overgrown.

The leaves are very large and tri-pinnate which gives 'Heavenly Bamboo' its common name.

There are many new forms of Nandina domestica which have recently appeared on the market. They range from the dwarfs  such as Nandina domestica ‘Nana Purpurea’ which grows 60cm(2 ft) which I think are best in containers as they do not have the elegant form as the full-sized ones. Nandina domestica ‘Plum Passion’ has great plum tinted blue-green foliage and grows 2m(6.5ft) by 90cm(3 ft) wide which is the normal size for Nandinas. There are also exciting golden-leaved  and yellow and white-fruited varieties which can be found so be on the lookout for more interesting varieties.

This dwarf Nandina would be best suited in a nice container.

Nandinas are fairly hardy growing in zones 6 though 10 or-10c.(14f.) with little damage as long as they are in a spot shelter from drying winds. If they do lose their leaves in a hard winter they often come back quickly with new stems coming up from the base, the old ones can be removed. In areas where these plants have become a pest it is important to remove the spent flowers so they do not set seed. Speaking of seed, this is a common way to increase your crop of plants, germination is best if sown fresh with all pulp removed from the berries. The other method of propagation is by semi-ripe cuttings in mid spring.

This Nandina domestica is well palced in a sheltered location with some sun.

Nandina domestica can be used in a variety of ways, as an informal hedge, mass planted, as an accent or for seasonal color. You will see it used in many public gardens as well as better institutional setting as it is a much more manageable substitute for true Bamboos.It fit well in asian, Japanese, understory or dappled and modern gardens very well. The graceful feeling of the plant is much appreciated by gardeners everywhere.

Semi-Cactus, Collarette and Decorative Dahlias.

The muted colors of the autumn season will soon be upon us, the plants are beginning to look tired from the long hot summer. The end of the season brings on a slow decline. It is harvest time, the moon is big and the crops are high and full of ripeness. Certain plants remind me of this season because I would only see them now when I was growing up in the north. Dahlias are the flowers I remember being huge and have brilliant and interesting petals and color combinations.

A sumptuously colored Dahlia with a 'Ball' classification of flower.

There are about 35 species of Dahlias which all originated from central America, from Mexico through Guatemala, Hondurans Nicaragua, Costa Rica and other areas. The first Dahlias which was documented were encountered by Francisco Hernández de Toledo(1514-87, who was a naturalist and physician to the King of Spain. He was sent on the first scientific exploration of the new world in 1571 and spent 7 years gathering and classifying specimens he collected and interviewing the local people on their use. His works were published in 1615.

The first species Dahlia recorded would have been single flowered and look something like this.

Later another botanist, French Nicolas-Joseph Thiéry de Menonville was sent to Mexico in 1776 to steal cochineal insects (the source of red dye at the time). He went unofficially succeeded in bring back the insects. In the notes of his adventure he notes Dahlias were unusually attractive flowers. Dahlias where first grown in Europe at the Madrid in the botanical gardens there in 1789. The seed had been sent from the botanical gardens of Mexico. The first plants were named  Dahlia coccinea in 1791.

Dahlia 'Bishop of Llandaff'(1924) is one of the most famous culitvars of the past and is now widely available.

Other seeds of different species where later germinated in England and roots were sent to Netherlands to grow. Crossbreeding began from these original collections of plants is where all our fancy Dahlias come from today. During the 19th century thousands of new cultivars where grown and the best were selected for their brilliant colors and unusual flower and petal forms. The name Dahlia honors Anders Dahl who was a Swedish botanist.

This brilliant bi-color Dahlia is classified as a ' Semi-Cactus' flower form.

Since 1900 flower forms have been classified into groups. Dahlias are now bred for competition which is very popular here, at this time there are test gardens and competitions which are judged. Kids love the flowers which can range in size from the small cm(2in) to 30cm(1ft) or more in diameter. The overall size of the plant also have an extraordinary range from less than 60cm(2ft) to 3.5m(10ft). The range of color and petal forms and heights is due to the fact that they are homologous and have 8 sets of chromosomes compared to the normal 2 which most other plant have.

This Dahlia cultivar exhibits not only very unual petals, but, also streaks of colors in them.

The popularity of Dahlias is partly do to the ease of growing them and their availability in such a range of colors and forms. You can buy them anywhere that plants are sold as roots, seeds or in packs of small plants.  Like all good plants they like rich, deep, well-drained soil with plenty of nutrients. They need full sun and plenty of water during their growing and blooming stages, this will help them avoid getting unsightly mildew(greyish powdery fungus on their leaves). The larger flowered types should be in a shelter  from strong winds.

The vivid colors of Dahlia flowers are hard to overlook in the garden at this time of the year.

Although Dahlias are considered hardy annuals and can take a touch of frost and survive If you want to save the tubers it is best to harvest them before this happens.  Dig them up carefully as the skin is thin and can be damaged easily.Remove the leafy tops and let them dry slightly, After they have dried a bit place them in a layer of dry peat moss. Place them in a cool dark place for over winter storage.  Check them periodically for any signs of rot or decay and cut it off or throw it out. You can have flowers for many years this way. In a few months you will notice small bud which show which to plant them. Plant them when all chances of frost is over or start them in a sunny location in your house a few weeks before you plan to plant them.

There are many classes of Dahlia flower forms, this is a beautiful Semi-Double form.

Dahlias are important to Mexico. The Aztecs grew and harvest the plants for food, medicinal and decorative  purposes. The strong woody flower stems were also used for water tubes and pipes. In 1963 the Dahlia was declared the national flower of Mexico.

Joy in the Late Summer Garden

Here we are in the last week of August, many of us and our children are getting ready to go back to school. The garden often is neglect now because we are busy with othr things occupying our time. late summer is a time of changing palettes in the garden, from the spring and early summer colors to the richer and often nuanced tones. One plant which is ever changing in color is one of the stars of the garden right now,that plant is the known ‘Autumn Joy’ Sedum(Sedum x‘Autumn Joy‘).

Sedum x 'Autumn joy' is an ever changing palette of colors.

‘Autumn Joy’ Sedum is one of the more common plants you will see in gardens  because it is very useful and easily propagated. It is a cross of two closely related species; telephium from Europe and spectabile (which supplied the pollen) which originates in China and Korea. These two species and several other similar more woody type, large leaved Sedums are now reclassified as the species Hylotelephium.

Sedum 'Autumn Joy' with its massive flower heads reday to burst open at Finnerty Gardens.

The meeting of telephium and spectabile occured at Georg Arrends(1863-1952) nursery at Wuppertal Germany near Cologne. Arrends was one of the formost perennial plant breeders of all time. He  introduced many new improved Bergenias, Asters, Campanulas and especially Astilbes. Sedum ‘Autumn Joy’ was originally called ‘Herbstfreude’ and it can be argued it is probably Arrends most popular and well known introduction of all. It was likely to have been presented to the garden trade in the late 1940s or early 1950s. It is hard to find a public garden which does not include these plants and from there many home gardens grow it as well.

The same border at Finnerty Gardens with 'Autumn Joy' Sedum in bloom.

The cross of telephium and spectabile into Sedum ‘Autumn Joy’ brought the best of the parents together. It improved the flower color by intensifying it, it also improved the overall flower head which is now massive. The othe improvement was in making the stems more strong and less likely to flop. These are all characteristics which endear this plant to many professional gardeners who love it for its long season of bloom and overall beauty throughout the year. The color palette and texture of the plant is also easily incorporated into many garden designs.

In spring the beautiful jade green leaves of 'Autunm Joy' sedum is an attractive addition to the garden.

Many of the reasons Sedum ‘Autumn Joy’ is used so much is its incredible versatility in where it can be planted and how it is used in the garden. This plant takes any kind of soil but prefers leaner, light sandy soil. Give it slightly less than an average amount of water, this will keep the stems more firm and the plant more compact.. The one thing they do not like is being in excessively wet soil for a long time as this causes rot. Full sun is the best although it tolerates light shade especially in very dry, hot climates. If the flower heads start getting smaller it is probably is time to divide the plant and this can be done at any time of the year easily, dig it up and pull it apart.If you want to keep the blooms divide in the spring or fall. Cuttings are also very easy to take and root.

Here Sedum 'autumn Joy' is seen in a border with Echinacea, Verbena, blue Lobelia and frothy Gaura in the corner.

‘Autumn Joy’ Sedum can be used for late summer color in sunny borders, perennial borders, as specimens or accents and for mass plantings. It also works very well in seasonal containers for patio or other places for a long lasting show of color. Sedums naturally look good with grasses, Rudbeckias, Asters and other later season plants. The flowers blend in nicely and the leaves have a cooling effect in the garden. As the flowers age their color deepens. Often these plants are left standing in the garden in the winter as the spent flowers stand up well to rains and even snow and the rustic shade of the spent plant is seen as attractive.

This clump of Sedum 'Autumn Joy is in a long border in Sidney which has Miscanthus, Rudbeckia, Lavenders and Asters.

‘Autumn Joy’ Sedum grows in zones 3 through 10 (-40c and f). This is a compact plant growing no more than 60cm(2ft.) high and by the same wide. These are fairly long lived plants and will give you pleasure many years.  They make good cut flowers and are long lasting, they also are excellent in dried arrangements. They are a good source of honey for butterflies and bees late in the year.

Fried Eggs and Really, Really, Really Big Poppies!

The laziest part of summer, temperatures are at their peak and I just feel like dozing. In the garden it is a quite time, many plant are going into their decline after blooming earlier the season. With the heat many plants will droop, some will become completely dormant and start loosing their leaves. Others now will shine and come into their season of glory while showing how resilient they are and carry on as if nothing is happening. The Matilija Poppy, California Tree Poppy (Romneya coulteri) acts like it is just another day at the office and look beautiful and refreshing as ever.

Romneya coulteri is known as the Matilija Poppy or Fried Egg Flower.

Romneya coulteri is found in southern California  ranging through the Santa Monica to the Santa Ana Mountains near San Diego and then into Baja in Mexico. They are normally found growing in dry washes and canyon and gulleys where the conditions are very dry and the soil tends to be poor. The southern plants are classified as Romneya trichocalyx or BristlyMatilija Poppy. there are also hybrids which are known and are in cultivation. For the common gardener like you or I we can safely consider them to be one plant type as all forms look and grow exactly the same.

Part of the charm of Romneya coulteri are the petals which bring to mind the most delicate silk or crepe paper.

Romneya coulteri was first brought into the garden by Dr. Thomas Coulter(1793-1843). He was a botanist and explorer who served in Mexico. While he was there he managed silver and lead mines in the late 1820s to early 1830s. In his spare time he would explore the area. He had the foresight to envision that great cities would one day be established there. When he returned home to Ireland in 1834 he brought with him a collection of dried plant materials, insects and rock samples. He later became curator of the herbarium at Trinity College, Dublin. Here his plant samples were studied and included in the national collection which is now part of the National Botanical Gardens of Ireland at Glasnevin.

A large suckering clump of Romneya coulteri or California Tree Poppy is found in the White Garden at Government House.

It was at Glasnevin that Romneya coulteri was first grown in a garden setting in 1875. The delay introducing is likely partly due to getting viable seed to germinate as well propagating it which is difficult.  Romneya comes from honoring Thomas Romney Robinson(1792-1882) an important Irish astronomer. Coulteri is named for Dr. Coulter who is mentioned above. The name was chosen by William Harvey in 1845 to honor the two men who were his contemporaries and friends in Ireland.

This Romneya coulteri is in a hot, full sun site on a street near Cook Street Village.

Even though Romneya coulteri comes from sunny California it grows very well in many other places which are not so warm or sunny. Here in the north(wet)west it is an increasingly common sight in larger gardens. people have come to appreciate its long blooming, drought tolerant qualities. Another thing that is loved is the beautiful grey green foliage which works so well with many other colors. The blooms also have a light delicate fragrance which is much-loved.

Like all members of the poppy family care must be taken when placing Romneya coulteri in the garden.  This not a small plant, in fact it can grow to nearly 3m(10ft) tall and nearly as wide, this is why this plant is often thought of as more of a shrub than a woody based perennial. California Tree Poppies spread by underground rhizomes which can go under paths, driveways and even houses and pop out on the other side. Here they generally grow 2m(6ft) tall or less. Choose a site which will give them the space they need and will not impact other more delicate or less vigorous plantings. these plants are not fussy about their site as long as it is well-drained, soil can be poor or rich, no amendments or fertilizer should be given. When first planting they need water about once a week and then in following years should be left alone.

Matilija Poppy stems are long and still and often need staking.

Romneya coulteri plants have stiff woody stems which grow best with scant water and full sun and less likely to flop. This stately plant works well in the back of borders or the very center of large beds where it can support other plants leaning and climbing up its mighty stems. It is great in dry areas or those which will naturally  have less pampering. It attract butterflies, bees and other insects. It would be useful in mass plantings or even as a very coarse tough groundcover for dry neglected areas.  In warmer areas it is almost evergreen, here it is often treated as other perennials and cut down in the fall when it goes dormant. It is rated as zone 6(-10f) by some authorities and zone 8(-12c or 10f) by others. I think must be related to the winter dampness and drainage.  Propagation is best done with young root cuttings.

The bristly seed-heads are rather small compared to the enormous 5-6in(12-15cm) diameter flowers.

The sap of Matilija Poppies was in the past medicinally for skin and gum problems and for stomach upsets. There is a charming legend relating to the flower which claims the petals of the flower were believed to have been made of the soul of a heart-broken maiden who died. The Chumash (native people of the area which this plant grows) gods changed her into the pure white petals.

On the Tropaeolum Trail.

When I was small we would go for walks with our mother in the neighborhood and stop and look at the gardens, some were interesting others where more playful and some just a plain messy. You could tell the ones who liked kids by the plants they often chose, fun ones like squashes, scarlet runner beans, and bright flowers like Cosmos, Marigolds and who could not resist Nasturtiums!  Nasturtiums(Tropaeolum majus) are a fond memory of many of us who had them in our garden when we where young.

The bright array of colors found in Tropaeolum majus always appeals to children of any age.

Tropaeolum majus orginally is from South America, growing in an area from Bolivia and Columbia and is said to be found in areas such as central Chile as well.  Nasturtiums were first brought to Europe by Spanish around 1500, it is likely seeds where carried back. In South America the plant was used for medicinal purposes such as treating coughs, colds, flu by creating at tea. Topically it was used in poultice for for cuts and burns. Nasturtiums are high in vitamin c and have natural antiboitics in them. It was in Europe that the plant was first used for culinary purposes.

Here the trailing variety of Nasturtium is used as a simple but charming ground cover that is a riot of color during summer and autumn.

As a culinary plant Nasturtiums have a lot to offer: the leaves, flowers, stems and buds can all be used and impart a spicy sweet flavor reminiscent of Garden Cress (Lepidium savaticum) or Water Cress(Tropaeolum officinale). The flowers and leaves are used in many ways from salads to sandwiches, in dressings and spreads. The flower buds are pickled and used as a substitute for capers. I like to use the stems as they are especially spicy and add them into salads, my dad who loved extra spicy things was surprised with the intensity of heat in them.

Nasturtium leaves are unusual as the stem is attached to the very middle of the leaf giving it a curious round shape which is part of this plants charm.

The unusual shape of the leaves and flowers lead Linnaeus to choose a an interesting botanical Latin name for Tropaeolum majus. ‘Trope’ is from the Greek tropaion or trophy which refers to how the round shields(leaves) and helmets(flowers) where hung on a pillar which was said to be a sign of victory on a battlefield.  The common name Nasturium comes from the latin ‘nastos’ (nose) and ‘turtum’ (torment) and this refers to the spicy taste of the plant. Majus just means big which refers to the size of the leaves.

The stained glass coloring of the Nasturtium flowers and the curious rounded leaves have inspired for many famous artists and writers.

Nasturtiums have long been known but during the Victorian era, into the early 20th century seemed most charmed by these plants. From Monet, William Morris, Moorcroft(pottery) to Tiffany’s famous glass, the plants where used everywhere as a charming and attractive subject. Nasturtiums of course are a famous subject for botanical prints. Who does not love a bouquet of the fragrant brightly colored Nasturtiums on a table or windowsill to cheer one up.

This bunny hides in the Nasturtiums in the Childrens Garden at Glendale Gardens.

Tropaeolum majus is an easy plant to grow for the new or junior gardener. The seeds are big and easily handled and once planted germinate and grow quickly. They are not fussy and like sandy light, poorer soils, but will do equally well in richer soils although it will produce more leaves and less flowers. Full sun is most important to get the best showing of flowers unless you are in a very hot climate where a little shade in the afternoon will be appreciated. although they are somewhat drought tolerant regular watering will insure your plants continue to bloom for a long time. dead-heading the spent blossoms will help the plant to continue to bloom for months. Nasturtiums are considered to be hardy annuals and can tolerate a light frost, a hard one will kill them outright.

The Nasturtiums here are a cheery welcome to this garden.

There are 2 main forms of Nasturtiums, the compact(or dwarf) and the trailing. The dwarf are at the most 45cm(18in) wide and tall with the trailing form being able to cover a 1m(3ft) space per plant. The beguiling flowers come in a vast tapestry of single-colors, bi-colors and blends ranging from the blackish-red ‘Mahogany’ to a pale buttery yellow and all ranges from red through scarlet, orange and yellows. Many named color varieties, singles, doubles and variegated(‘Alaska’)  and dark leaved(‘Empress of India’)  forms can be found in seed strains and are cheap to buy. Seed is easily saved for next year and often will reseed and grow in the same spot for many years.

Nasturtium 'Mahogany' has the darkest flowers that i have seen here in Victoria.

Tropaeolum majus can be used in the garden in so many ways: edging, colorful filler for early bulbs and bloomers, childrens’ first garden, ground-cover, edible garden, fragrant garden, self seeding garden, old fashioned gardens, window boxes and containers, formal and informal settings and as artists subjects and fairy gardens.
