Plants that did make sense to have in my small garden

A dwarf, big flowered blue columbine: Aquilegia discolor, most probably a cross (from Seedex as A. saximontana)

True that if we would grow only ‘reasonable’ plants, our gardens would lack all spontaneity and wonder. But because I can now easily enjoy them in containers, and not worry about their relocation, I think a bit of praise is warranted.

On the other side of the container, a tiny hardy ginger: Roscoea tibetica (from Lost Horizons) – very precious, after the bad winter we had, who knows if I will get to see the other Roscoeas from the garden.

From another container, the most fragrant, fringed Dianthus I know: Dianthus petraeus (from wild collected seeds in the Carpathian Mts.) Too bad I cannot insert a ‘scratch patch’ with its perfume.

A rock jasmine: Androsace sarmentosa – a small piece I saved from an old plant, I hope it will thrive again (or set seeds, or better both).

and more are on their way to flower…

Uvularia grandiflora – Large-flowered bellwort, Merry-bells

Spring is a busy time when it comes to wildflowers – lots of species start flowering almost at the same time, especially when the springtime gets condensed in a couple of months. While I try no to discriminate, some will be overlooked for now and I will highlight just a few; for example would be hard to ignore the Merry-bells! They start to flower at the same time, or a bit after Trillium grandiflorum, depending how shady the location is.

Uvularia grandiflora - just starting to flower

Uvularia grandiflora

Unlike some other wildflowers, Uvularia grandiflora is not a stranger for the cultivated woodland garden. Although not that popular as it should be, it is appreciated for its elegant habit and clusters of pendulous yellow flowers with twisted tepals, always ringing loudly for attention.

More than this, it is an important food source in the spring, providing nectar and pollen for bumblebees, mason bees and other bee species. It will grow to form a nice, tight clump in a few years, so it can be used solitary although it looks fantastic in large groups.

Note: Another native bellwort – Uvularia sessilifolia has smaller flowers and non-clasping leaves.

The not so recent news from our small Canadian horticultural world is that Wrightman Alpines, a premiere alpine plants source from Ontario, is relocating to St. Andrews, New Brunswick. Fortunately, there is nothing to worry about as the mail-order will go on as usual, therefore, rather than saying goodbye, this is more a Hello to a new adventure!

Native alpine plants, little known plants, impossible plants…

Clematis columbiana var. tenuiloba, Matthiola trojana and Eritrichium howardii

But for the few of us lucky to be able to drive for their open days last weekend, it was the moment to say goodbye and to wish them all the best in this new adventure of relocating their family and nursery in a new place. After operating for more that 25 years from this location, this is without doubt a courageous endeavour and needless to say heartbreaking because parts of the rock gardens, including plants will have to be left behind.

 One more look to the gardens and Hello to a New Adventure!

 As soon as I’ll sort out the pictures we’ll have a last walk throughout the hoop-houses – the list of plants for my future rockery keeps growing longer…

And in the gardens last year

 

A few weeks ago I stumbled upon this Primula that was showing promise to be a great Primula-rina!
Primula frondosa foliage

The Ballerina – Primula frondosa (a bit elongated in a container in early spring)

Last time when I had visions of dancing plants it was two years ago because of a twirling Arisaema – it is not that often to discover a first class ballerina!.

Primula frondosa is a dwarf, farinose primula endemic from Bulgaria where it grows on cliffs at 900-2000 m altitude, in partly shaded, moist crevices. It is very hardy and will show up from under the snow, with a tight silvery rosette (you may wish that it remains like that), but then the leaves expand and remain powdery only beneath (but the flowering stem and flower pedicels still covered in silvery hairs). A very floriferous primula: umbels with up to 30 pink, delicate flowers with a yellow eye in early spring.

Primula frondosa flowering

Primula frondosa in full bloom right now ( 2-3 seedlings were planted together in the fall)

Sometimes mistaken for P. farinosa (and vice-versa, but P. farinosa has white-farina on both side of the leaves, and it flowers much later). Both are commonly called Bird’s eye Primulas.

Propagation: very easy to grow from seeds (like other Primula spp.), and it will start flowering in the second year – soooo gratifying!

 

Corydalis from the Greek ‘Korydalís’ meaning ‘crested lark’

Someone lucky enough to go hiking in the Carpathian Mountains in late April-early May would be surrounded by multicoloured masses of Corydalis solida – Fumewort (or ‘brebenei’ in my native tongue). There is a great variation in flower colour from white to pink and purple and actually the best forms of C. solida on the market today trace back their origins to Transsilvania (Romania) and Penza regions (western Russia).

This year, in sync, the ones from our garden are blooming at the same time:

Corydalis solida 'George Baker'

The renown Corydalis solida ‘George Baker’ (from Gardenimports – I am not really sure if it is the real thing but still a good red form)

Corydalis solida 'George Baker'3 An ephemeral at superlative – it appears fast with the temperature raise in the spring, and then disappears quietly after a few weeks. But for the brief time when it flowers, it will fill your heart with unconditional love for the years to come. The deeply divided ferny foliage and long spurred, tube-shaped flowers are adorable providing the much needed burst of colors after our long winters.

C. solida purple

Corydalis solida – in its usual purple form (from Lost Horizons)

They also make for very good photo-subjects after rain

C. solida ‘Beth Evans’- is a large-flowered form, with pink flowers; slow to increase.  They are very delicate when in active growth; to be moved, mark their place and lift up the small tubers (bulb-like) as soon as they go dormant or in the fall.

Corydalis solida 'Beth Evans'

Corydalis solida ‘Beth Evans’ (from Fraser Thimble Farm)

Due to its ephemeral nature it is offered mostly by specialized nurseries/mail-order operations. For part shade and moist conditions when in growth, then it prefers to remain on the dry side for the rest of the season. I particularly like them planted close to ferns or  ornamental grasses where they fill in the space just perfectly in early spring. They interbreed easily and will seed around if happy forming multicolored colonies.

Best not to be a purist when it comes to Corydalis solida!

This is just a small glimpse of the Corydalis solida world – there are many other named varieties. I already wrote about other wonderful Corydalis species – do not be afraid to become a corydaphill!

Note: If someone doesn’t know it, the absolut Corydalis guru and bulb expert is Janis Ruksans from Latvia – on-line catalogue here: Rare Bulbs
 

 A gardener’s look at how our preconceived ideas prevent us from experiencing new plants in the garden.

Most specialty nurseries nowadays are carrying a wide range of Solomon’s Seals – Polygonatum spp., of which quite a few don’t look at all like the common, North American native Polygonatum biflorum. Although the Great Solomon’s seal is a great addition to any woodland garden of a certain size, its size and spreading behaviour have been extended wrongly to the genus Polygonatum in general. If we are willing to look beyond, there are species and varieties that look and/or ‘behave’ in the garden completely different. I cannot say it better than Tony Avent from Plant Delights Nursery did when talking about Polygonatum kingianum: “forget everything you know about Solomon’s seal, except that it grows from a rhizome in the shade.”

I am sure the list can be longer but I’ll resume to a few species that I have images and are available at Lost Horizons Nursery in Ontario.

Polygonatum kingianum grows to 1-3 m tall, erect or as a climber; its leaves are narrow and arranged in whorls, each ending in a tendril-like tip. Flowers can be white to pink or orange and berries red. Flora of China specifies it is a highly variable species, which stands true for a few others Polygonatum sp. with whorled leaves.

 Polygonatum verticillatum has also narrow leaves in disposed in whorls (but no tip-tendrils) and creamy-white flowers. A very tall form in cultivation is P. verticillatum ‘Himalayan Giant’. Another beauty with narrow, whorled leaves and smoky-rose flowers is Polygonatum curvistylum (I don’t have an image so you’ll have to believe me). Another species presented in the gallery, with umbel-like inflorescences might be P. zanlanscianense, but I’m not very sure. For more unusual species Flora of China is a good source of descriptions, although in some cases given their variability is hard to ascertain a proper identity, looking only at a few plants.

 My preferate – Polygonatum hookeri is a dwarf Solomon-seal that you’ll fall in love with at first sight.  It is a native from parts of China and N. India, where it grows at altitudes over 3000 m. It reaches only 10 cm in height and the leaves are crowded on the stems. The pink or lavender flowers resemble those of a hyacinth, and berries are red. In time it will form a lovely groundcover mat allowing other taller plants to peak through. Perfect for a small rockery in part shade. Available also at Wrightman Alpines – after all it is an alpine solomon’s seal!

 

 

 

Another great Arisaema that flowers in early spring is Arisaema galeatum. It is another story than A. sazensoo because it has a really big tuber. It is said that can grow to half a kilogram! Last year when I was checking the tuber in early March I caught it just starting to grow and it looked very appealing to me – with a dark-chocolate coating and raspberry syrup on top would be delicious! But I put myself together… This is an Arisaema from the Himalayan range (NE India to Bhutan), which grows during the mansoon months and then the leaves start withering in late summer and goes dormant early. Good to keep this in mind as it shows its requirements for a very good drainage from late summer to fall, and during winter of course.

The flower emerge on the same time with the leaves, on a short peduncle and it has a helmet-like (galeate) spathe, similar with A. ringens. It can be green or brown with whitish veins and has a white, translucent spadix that ends in a thread like whip.  I like to call it Dolphin cobra lily, because that’s what it suggested to me first time when it bloomed – a dolphin emerging for air from within the leaf! 

Just like its sister, A. ringens, the huge trifoliolate leaf is very ornamental. Actually, I consider it among the most beautiful from all Arisaema species I’ve seen. It unfolds slowly and the back pattern with accentuated purple ribs makes it mesmerizing to watch.

It did form two tuberlets two years ago (not a great rate of offsetting), from which one even produced a small flower in its first season! Unfortunately, the rainy weather we had late summer to fall it proved fatal for the smaller size tubers. If someone wants to give it a try I suggest container culture, so it can be moved to a dry place in late summer, or if in the garden a real well drained area, like close to a tree or shrub that would remove the excess water and also provide the part-shade required.

 

This is an updated post on Arisaema sazensoo – I have more ‘data’ to share now than last year. I am always in a mood for any Arisaema, but especially for the rare ones like A. sazensoo.

Arisaema sazensoo, is one of the first Arisaema to emerge in the spring, just like its cousin A. sikokianum. It is native from Kyushu, Japan and resemble a little A. sikokianum but the spadix doesn’t have such a pronounced white ‘pestle’. The spathe is usually deep purple, recurved over the spadix and the leaves are trifoliolate, like you can see in the images. It was thought to resemble a Buddhist monk in meditation – ‘zazen’, hence its name sazensoo, or at least that’s what I read. Anyway, you can tell it is a very charismatic Arisaema!

Arisaema sazensoo

Arisaema sazensoo

Another characteristic is that it stays in flower over a very long period of time, comparing with other Arisaemas. It had one attempt to form seeds, which proved sterile, but two years ago in late fall I had the very pleasant surprise to find that it had produced an offset (a tuberlet)!

On a few websites you’ll read that A. sazensoo is a non-offsetting species, but obviously someone got it wrong. In the images below I can present now the tuberlet that has grown quite well in one season (A. sazensoo doesn’t have a big size flowering tuber). More than this, the old tuber shows very clear another tuberlet (which is best left to detach by itself).

Like many other Arisaema species, it prefers a part-shade location and can be grown very well in a container, where a good drainage can be easily provided. Best transplanted in late fall with fresh potting mix and kept dry over the winter.

“One poem/ per blossom is not enough/ for a peony.” – Ryumin

And if I may add, one picture per blossom would not be enough for a peony either. I realized this at New York Botanical Garden when the herbaceous Paeonia (P. lactiflora) collection was in full bloom. There are plenty of books and websites devoted to peonies. What I find fascinating is how this flower has become so revered in the eastern countries, to the point that peony-viewing was a festive occasion in the Japanese gardens, for example. It was associated with good-luck, prosperity; it was a status and a symbol of good fortune. Peony images can be found in the artwork of many Asian artists, in paintings, tapestry, porcelain and literature. For the peoples from other cultures, the peony may be just a pretty flower, but even so we can all agree that true beauty doesn’t need description. That’s why I put together this album: one picture and one poem per blossom; they are not enough….

Yet another subject that I don’t have enough time to dedicate – the climbing Aconitum species. While the old fashioned monkshoods have been in the gardens and are well known for a long time (yes, despite the fact that they are highly poisonous), the climbing ones are still to raise a few eyebrows. Most of them, like A. hemsleyanum, A. volubile, and A. uncinatum with the usual blue flowers are a bit more common than this one that makes me start the conversation: Aconitum alboviolaceumfrom China, Korea, Far East Russia, where it grows in “forest, scrub in valleys, mountains; 300-1400 m” (Flora of China vol.6). Two varieties are recognized: var. alboviolaceum: with twining stems – 100-250 cm and var. erectum – stems up to 30 cm tall.

Aconitum alboviolaceum

Aconitum alboviolaceum var. alboviolaceum

Raised from seed and in its third year now, it twined very gracefully around a snake bark maple in the Display Garden at Lost Horizons, without becoming too cumbersome. In a perfect match with the snake bark, rows of monks with pink&white hoods are now, slowly climbing up….

 

 

 

 

The Plant Gold Rush continues with the most precious of finds: the alpine golden nuggets. We found them at Wrightman Alpines during their open house last Sunday. It had been a while since I was lucky to admire their Saxifrages in flower, so we made another trip that turned out into a photography extravaganza.  Many ‘golden nuggets’ were either in flower or at their best foliage; we took advantage of our most kind hosts, Irene and Harvey Wrightman, and poked around every corner of their wonderful rockery garden and nursery. Even for a plant connoisseur the richness of plant species they have can be a bit overwhelming to digest, so I’ll take it slow and there’ll be more to come…

Paeonia suffruticosa ssp. rockii

At this time of the year, after admiring the most impressive clumps of Paeonia suffruticosa spp. rockii, the best would be to explore the rock gardens around the house before heading into the hoop houses (although being very detailed people we did the other way around).

 Enjoy a few images from Wrightman Alpines Nursery rock  gardens

Scutellaria orientalis ssp. pinnatifida

Scutellaria orientalis ssp. pinnatifida – a very floriferous and bright Scutellaria (from Turkey at 2500 m)

The wonderful day spent among the plethora of alpine species (native and non-natives) brought to my mind a few places we traveled to and I wrote about – see the Botanical Trailblazers page. Gold mines full of ‘golden nuggets’ await to be discovered almost everywhere – start exploring!

The Latin word saxifraga means literally “stone-breaker”, from Latin saxum (“rock” or “stone”) + frangere (“to break”). Pliny the Elder thought the plant was named like this because at the time it was given to dissolve gallstones (another example of the Doctrine of Signatures). Even so, Saxifraga is a very good name for a plant growing in rock crevices.

Saxifraga 'Redpoll'

Saxifraga ‘Redpoll’

Some of my regular readers might have noticed my penchant for mountains, and of course, everything that grows on them. The seed collections from the Carpathian Mts. we did last summer, my limited garden space (at some point there is no other way to expand but UP), and the fact that every year I plan to do it and it never happens, all combined together and I finally made it to the only nursery specialized in alpine plants from Ontario: Wrightman Alpines .

Alpine house with Saxifraga

Alpine house with Saxifraga and many other species

It is a small size operation (mail-order) but growing a vast array of alpine plants from all over the world. On their website, besides perusing the catalogue, with some species in very short supply, you can watch a few interesting videos about building clay crevice gardens, planting tufa and much more. Alas, this cold month of March made it that many species were behind their usual growth, but to put things into balance, the Saxifrages were in flower. Skilfully grown in small tufa pieces by Harvey Wrightman, they were looking like miniatural rock gardens in themselves.

The genus Saxifraga is quite large, comprising a wide range of mostly perennial plants, many of which are alpines. According to the Saxifraga Society there are some 480 known species and countless garden hybrids. The sections that are of garden interest are: the ‘mossies’ (section Saxifraga), the ‘silvers (section Ligulatae) and the Kabschia and Engleria subsections (of section Porphyrion).

Now, if I made you think I know what I’m talking about, you are wrong (in this case). When I’ll be done with the many other genera I’m working on, I’ll get to the Saxifraga too, but that might be a long time from now. Unless you really need a botanical challenge in your life, I suggest that you do like me: try to have fun growing a few of them in your rock garden.

For the connoisseurs, I cannot end without showing a real alpine gem: Dionysia tapetoides – a cliff-dweller, native from Afghanistan, hard to grow and equally hard to find.
