The sleeping beauties

After an early winter arrival I am in the rush now to tuck in safely my sleeping beauties. The garage serves as a ‘winter storage/garden’. In what I call sleeping beauties I include various species done from seeds that have one thing in common: that they are ‘sleeping’ in their first season, totally or partially. Sleeping is not quite a proper term because they are actually growing but mostly underground. However, for a long period of time you are staring and caring for what, some may call, empty pots.

They are mainly hypogeal germinators that in their first season will only emerge the radicle and grow a young tuber/rhizome: Paeonia species, Trilliums, some Lilium species… Paeonia mlokosewitschii seedlings resemble little creatures hungrily sucking water and nutrients from the soil mix ;)

Paeonia mlokosevitschii seedlings

Paeonia and other sleeping beauties

Paeonia rockii - white

Others like Glaucidium palmatum, will germinate totally underground or above, but remain arrested at the cotyledons stage and spend the season fattening up a growing point underground. The whole process can be sped up a bit if you can sow right away in late summer and/or treat with GA3.

I can already envision their awakening next year, after the Spring’s big kiss!

I know that many don’t care to start from seeds species Paeonies because it will take at least 3-4 years until they start flowering but their spring foliage is equally mesmerizing. For the same reason it is not very easy to find to buy them and when available are quite expensive. Better start them from seed – in a blink of an eye they will grow, prosper and flower! I do not have such seeds to offer yet, but most often you will be able to get hold of a few Paeonia species through Seed Exchanges.

PS. NOT recommended to scratch the pots, or remove the seedlings, like I did; be patient until spring. In my excuse, I needed pictures so I can share the experience.

No-DOD’s

Propagation, Wildflowers of North America

(DOD meaning: Dead on delivery)

I don’t know precisely if the DOD term was coined by the renowned Prof. Norman Deno but surely he reminded me of it while reading a delightful Bulletin of the American Rock Garden Society from 1991. DOD refers to the fact that seeds that require to be kept moist after collecting, when stored and/or delivered otherwise (by Seed companies or in Seed exchanges), are actually dead and there is little to expect of them in terms of germination. In his article named – Fatal Treatments of Seed he elaborates on how to kill seeds of 12 species by practicing wrong techniques of storing and/or germinating. For Trillium albidum, Fatal means: dry storage.

Same goes for many other Trillium species, and among them, Trillium grandiflorum. After collecting (see how the fruit looks when it’s ready), such seeds should be either sown right away or stored moist. When kept at room temperature, some seeds will emerge radicles by fall. The others, like in other hypogeal germinators, will grow a radicle/baby rhizome or tuber in the coming season, and then send up the first leaf only after another cold cycle (that means in their second year).

These are a few Trillium grandiflorum seeds with emerged radicles that I found last week, during my routine check of the moist stored seeds. A few more pots were added to my collection and I am looking forward to see these little Trilliums sending up their first leaf next year! The other seeds are still in moist storage, awaiting…

Providing moist-packed seeds it is a lot of work but BotanyCa will not be responsible of any DOD’s! See all the Moist-packed Seeds from the Shop.

(If someone knows of other species that would benefit from moist storage please let me know – Contact)

And here’s the link for the ARGS Bulletin -1991 (open as a pdf). It contains great articles like: Saga of a Woodland Garden by Harold Epstein and Hepaticas and Anemonellas by Jeanie Vesall to mention just a few…

The Beauty and the Parthenocarpy – Acer triflorum

Gardens, Plant portraits, Propagation

Beauty is found in almost any maple tree, even if we are to consider only their colourful fall display. The Beast shows its ugly head especially in the case of trifoliate maples and is called parthenocarpy. As a remainder, this means production of seedless fruits (without the fertilization of ovules).

A really undesirable trait, especially for species with indehiscent fruits (samaras, nuts, achene), either if we want their seeds for consumption or to use them for propagation! This is also the explanation for the rarity of some magnificent tree species in our landscapes. Acer griseum, the best known of the trifoliate maples presents parthenocarpy to some extent but not as much as the beauty called Acer triflorum.

Acer triflorum

A trifoliate, very hardy maple from Manchuria and Korea “simply an outstanding small specimen maple, lovely foliage, exquisite bark and small habit contribute to the overall landscape effectiveness…; uses for good trees are endless” (Michael Dirr)

I did a little experiment with about the 60 seeds I had and a pruning shear. By nicking the end of the extremely hard samara and then cracking it longitudinally you can extract the seeds, if any. I found 3 viable seeds and 3 aborted (stenospermocarpy) – about 5% viable seeds!

PS. One easy method to separate seedless fruits is to check if they float; the ones with seeds will go to the bottom. This is recommended for many species but actually not necessary; it is useful though for fruits (like samaras and nuts) when it is hard to say if there are any seeds inside.
The fruit wall is so hard in Acer triflorum that it needs lots of stratification just to wear it down, so I preferred to extract the seeds (I didn’t expect to find any, but perseverance paid off :)

A chic hat

Medicinal plants, Propagation

Update: ID as Aconitum variegatum subsp. paniculatum

All Aconitum species are wearing cool hats but this one in particular with the hood on one side looks very chic. Growing Aconitum from seeds that are not properly identified is quite a pain, but worth the trouble.

All monkshoods are equally beautiful and deadly, with spikes of violet, dark blue, yellow or white hood-shaped, complicated flowers that one needs to know the terminology in order to ‘read’ their characters. Species are usually described on the basis of root and flower morphology.

Update: Aconitum variegatum subsp. paniculatum

After lots of searches, pictures, dissections… this one was narrowed down to Aconitum variegatum subsp. paniculatum (syn. Aconitum degenii) or A. variegatum subsp. variegatum. We’ll know for sure in late fall after I’ll dig it up and see the tuber shape; and maybe I’ll have a seed or two but glad to hear other opinions…

Aconitum variegatum: sepals (hood with pronounced rostrum) and petals with coiled nectary spurs

Before being praised as a garden plant, Aconitum was considered (and still is) “the king of the poisons” (Europe) or “the king of medicines” (Tibet and China), depending on where it grew, but this is a good subject for wintertime storytelling…
It is a good idea to wear gloves when doing anything that involves touching an Aconitum. It contains highly active and toxic alkaloids.

For Seed trade – Helleborus purpurascens

Botanical travels, Plant portraits, Propagation

Update: since I wrote this post in 2014! we now have the plants grown from wild collected seeds in the Carpathian Mts. (2 different accessions) flowering well and rewarding us with seeds. Nothing is more satisfying than to see plants grown from few seeds found by chance growing well in the garden. This species is increasingly rare in the wild; growing it in the garden it is also a matter of conservation at this point. The greenish-slate gray with back dusted purple flowers are exquisite! not to mention the foliage.

“I am not young enough to know everything” – Oscar Wilde

A quick post because I just ‘discovered’ that Helleborus purpurascens seeds are best sown fresh in the summer. They need to go through a warm-moist period followed by cold-moist in order to germinate best. Older seeds will still germinate but in a lower percentage. Helleborus is one thing I have never done from seed (members of Ranunculaceae are notoriously difficult germinators). This is a rare Helleborus species distributed only along the Carpathian Mountains range, up to central and northern Hungary. Interestingly, it can be found growing in full sun, in open alpine meadows and also under dappled shade in beech woods.

Helleborus purpurascens growing in full sun in native habitat – Carpathian Mts.

Graham Rice, the authority in all Helleborus matters, has an extensive article on H. purpurascens on his website, you can read it HERE. In a bit of a hurry, I will quote him so no one can say I am biased because of its origins:

It is “one of the most captivating species for its engaging habit of flowering so enthusiastically, for its subtle metallic tints… The foliage too is unlike that of other hellebores, in that it radiates from the tip of the petiole in a neat circle.”

As for the flowers, a few forms that are known from Botanical Gardens: “are purple in colour with dark veins, slightly pinkish towards the base and netted towards the edge; some flowers have an overall green haze…In a second form which reaches 15 in in height the flowers are smoky blue-purple in colour, darker outside than in, with slightly reddish veins inside and green nectaries. Other forms may be slate purple or deep purple outside, shining pinkish shades….”

Helleborus purpurascens – from what’s left it seems matching the description!

A truly collector’s plant, so this is a call for a seeds trade – if someone wishes a few fresh Helleborus purpurascens seeds to sow them right away, please get in touch with me here, on my email or at infoATbotanicallyinclined.org (of course replace AT with @

It would be a pity not to have them all germinating well – still enough summertime left!

A risky business – Polygala paucifolia

Plant portraits, Propagation, Wildflowers of North America

I think some are imagining that trying to open a business of selling wild collected seeds is a breeze – happily wandering in fields and mountains and grabbing here and there whatever comes under your eyes. Well, very far away from the truth. For example, who would think about stumbling into a massasauga rattlesnake (the only venomous snake in Ontario), while collecting Polygala paucifolia seeds!

: Massasauga rattlesnake (Sistrurus catenatus)

The timing to collect Polygala is almost impossible; the fruiting/seed setting is usually low and then the seeds are equipped with elaiosomes that ants will carry away very fast. So, there is no wonder that seeds are almost never offered and, although desirable, neither are the plants! Looking at the flowers, you understand why all this is worthwhile!

: Polygala paucifolia

My germination trials with Polygala seeds showed that dry stored seeds in the fridge, sown in the spring germinate very well, and also the seedlings are developing very well. Seeds stored moist-cold, germinate later and in a lower percentage.

: Polygala paucifolia seedlings – germination 95%; they may look small size but remember that this is a little plant

Would you care for some seeds? - click

PS. Keep your eyes wide open when hiking in the rattlesnake habitat! When moving, it makes a low rattle noise to make you aware, but when standing still it is very well camouflaged and it doesn’t rattle. They give birth to live baby-snakes, finger-size but already venomous! It is designated a species at risk in Ontario – more about it on Reptiles and Amphibians of Ontario website.

Rapunzel’s flower – Phyteuma

Alpine plants, Gardens, Plant portraits, Propagation

People in Europe call this member of the bellflower family (Campanulaceae) after many names: devil’s claws (Germany), Oxford Rampion (England), Raponzolo (Italy), and so on. We could definitely give it many other common names; I like to think of it as Rapunzel’s flower.

Phyteuma is strictly a European genus with quite a few species, not very often seen in the gardens. Phyteuma scheuchzeri, flowering now in one of my rock-containers is the most common in cultivation (I was aiming for P. sieberi, maybe next time…).

Phyteuma scheuchzeri

It doesn’t look like a bellflower, that’s for sure – it looks much cooler! In Phyteuma species the flowers are grouped in spiked, ball-like inflorescences (aka. floral sea creatures :-) which at full bloom ‘explode’ becoming fluffy. They can be found growing in a variety of habitats, with P. sieberi being the most alpine.

Phyteuma scheuchzeri

Another mountain growing Rapunzel’s flower is Phyteuma orbiculare, photographed here in a rich sub-alpine meadow in the Carpathian Mountains:

Phyteuma orbiculare

Propagation: easy enough from seed (very small, fine seeds just like Campanula, sow superficial); most are warm germinators.

And just because I like word rhymes: Did you know that Phyteuma has a sister named Asyneuma? Another great but very little cultivated member of the bellflower family.

In praise of little plants I

Alpine plants, Gardens, Plant portraits, Propagation

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)

: Aquilegia discolor cross

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.

: Roscoea tibetica

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.

: Dianthus petraeus

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…

A Primula-rina

Gardens, Plant portraits, Propagation

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

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 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!

The Magic of Germination

Propagation

Using giberellic acid as an aid in germination

More species are germinating and because it’s still cold outside it’s a good time to ‘blag’ a bit about the germination. Each individual seed is a little wonder in itself: it does contain the plant we want – only if we can make it germinate! What I don’t like when growing from seed is not the ‘un-germination’ but the incertitude of what happened – what went wrong? – bad seeds, bad soil mix, too deep, too cold, too dry, not enough light, too much light… Also toooo much information on the web now can make things even more confusing. Here I’ll talk only about what I personally do.

Glaucidium palmatum seed germination

Quite a few species (the most desirable) require ‘special treatments’ for germination like: stratification (moist & cold), alternation of cold and warm periods, incantations, sanding, soaking in GA3, frustrations… you get the idea. If you cannot easily provide a cold and moist period, the treatment with GA3 (acid giberellic) works in some cases wonders. I really like the convenience of GA3, which eliminates some variables from the process.

Aquilegia-canadensis-semi-double-form-seedlings

Aquilegia canadensis – semi-double flower form seedlings

There is no need to seed way ahead of time or get buried under endless small pots that will get lost in the sway of other spring garden jobs. If the seeds are viable, they’ll germinate; if not, at least you’ll know it wasn’t your ‘brown’ finger at fault. Good to know, however, that GA3 at inappropriate concentrations can also destroy the seeds or lead to poor quality seedlings.

These are two methods I use:

1. Keep seeds in their package in the fridge (dry storage). When time to sow, prepare a GA3 solution 500-1000 ppm, soak seeds until next day, plant them in pots, cover with a thin layer of mix – place under lights (or outside if you sow late spring).

2. For the most recalcitrant – place the seeds into a moist paper towel inside a Ziploc bag, keep in the fridge (moist storage). When time to sow, squeeze the moist paper and add the GA3 solution over seeds, then keep until next day and then sow.

Germination should occur in 1-2(3) weeks.

Most excited about Thalictrums I am trying this year: T. delavayi – a Chinese meadow rue, with large lilac-mauve flowers (petal-like sepals; the one I bought a couple of years ago was really small and didn’t make it) and T. isopyroides with a really tiny, steel blue foliage that can grow in full sun – would be good for a rockery (from Turkey, Iran, Syria, Altai Mts.).

Note: Aquilegia also prefer/require light for germination so you should cover them with a very fine layer of potting mix (in case you forget about this they’ll still germinate but much slower).

A study in contrast – Aquilegia species

Plant portraits, Propagation

A group of plants that I really like and hope to increase my collection, are the columbines: Aquilegia spp., and in particular, of course, the alpine columbines. In contrast with the more regular garden Aquilegia varieties, the alpine ones are short in stature but bearing large flowers. In most cases they have a delightful bluish, compact foliage, which in itself makes a wonderful addition to any small rock garden.

Aquilegia scopulorum x coerulea in the rock garden at Wrightman Alpines

All Aquilegia are important food source plants for bees, bumblebees, hummingbirds and hawk moths. Even just for this reason one should include them in the garden. Interesting fact, biologists found that the length of the nectar spurs in Aquilegia evolved to allow flowers to match the tongue lengths of their pollinators. Species with very long nectar spurs, like A. coerulea are pollinated by hummingbirds and hawk moths, while the short spured species, like A. canadensis are fancied by bees and other short tongue insects.

Aquilegia coerulea (Colorado blue columbine) has flowers with very long nectar spurs that look like space ships or sea creatures, wherever your imagination tends to go, up to the sky or down in the ocean. Very variable in height, anywhere from 15 to 90 cm and in flower colours – from white to pale or dark blue; also there are reports of a variety with spurless flowers!

I am greedy when it comes to columbines. This spring I am looking forward to see flowering (and take more pictures) in my rockery a few alpine columbines I grew from seeds: A. jonesii – the smallest of columbines, A. saximontana and A. discolor (that is if my seedlings survive the record low temperatures we have this winter).

Also ready to greet the pollinators this year: A. nigricans (Carpathians Mts. collection), A. alpina and A. atrata.

I would note that most Aquilegia species are polymorphic and difficult to define adequately. Some of the variability is because of introgressive hybridization (Flora of NA). Even distantly related species of columbines are often freely inter-fertile, hence the multitude of hybrids and cultivated forms available. Also, this poses a problem for seeds collection, especially in the case of cultivated varieties if one requires true to type species.

In a mood for Arisaema part II – Arisaema galeatum

Gardens, Plant portraits, Propagation

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.

In a mood for Arisaema – Arisaema sazensoo

Gardens, Plant portraits, Propagation

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

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.

A yummy treat – Polygala paucifolia

Plant portraits, Propagation, Wildflowers of North America

Polygala paucifolia - in the Bruce Peninsula, Ontario

One of my goals is to concentrate on the propagation of a few N. American native plants that would be as prized in our garden as any Chinese or S. American novelties. The hype of using native plants in our gardens and landscapes it always cut short by their difficulty to propagate (and by the lack of available seeds collections, of course). Whatever doesn’t fit into the profile of mass-production has been abandoned or perhaps not even tried in cultivation.

Besides serving an ornamental function, expanding into cultivation a few of the hard to find and/or propagate N. American species, would serve also a conservation purpose by maintaining and enriching the genetic material/ biodiversity through sexual propagation.Conservation through cultivation, (aka propagation) has already proved its importance in a few unfortunate cases of species extinct in the wild but saved, at least temporarily, in gardens sanctuaries.

“No, no! The adventures first, explanations take such a dreadful time!” – Lewis Carroll: Alice’s Adventures in Wonderland

OK. Last year we were able to finally collect a few seeds of Polygala paucifolia –Gaywings or Fringed polygala This is a low growing plant found in dry to moist woods, in part shade. It flowers in May-June and the pink-purple flowers are quite unusual – they have 3 short and 2 long wing-like sepals and 3 joined petals with a frilly crest at the tip. Fruit is a capsule. The seeds present an appendage – elaiosome, which is associated with ant dispersal – now you see where I’m going? A bit too late and the seeds are gone. The appendage contains lipids, proteins and starch, which serve as a reward for the ants. They drag the seeds to their nests to feed their youngs on elaiosomes and thus provide the service of dispersal. I bet they are very yummy!

The germination ecology for species from Polygalaceae has not been investigated in detail. I found a study claiming that for P. paucifolia, 4 months of dry storage results in an increase in germination. Other Polygala species are known to require pre-treatments for germination. Anyway, I don’t have that many seeds, so for this year I’ll try two variants: dry storage and moist-cold stratification until sowing in the spring.

We shall see…the seed adventure continues!

Note: Many spring flowers from the temperate climate rely on ants to disperse their seed (myrmecochory – I wouldn’t try pronouncing this); from the very well known: Trillium, Hepatica, Corydalis, Dicentra…

Bristly Sarsaparilla

Plant portraits, Propagation, Wildflowers of North America

While gazing to the rocky shores of the Georgian Bay in Killarney, one plant kept drawing my attention (and camera) – the bristly sarsaparilla: Aralia hispida. Growing in any small crack of the big granite boulders, with shiny leaves and blackish fruits proudly swinging in the wind, it made me think, again, how many wonderful, garden-worthy, but underutilized native plants are around.

Drought resistant, growing in full sun in rocky, poor substrates, this Aralia could be a prized plant for any garden. The leaves are twice pinnately-divided, and the stem base is covered by bristly hairs and becomes woody persisting through the winter. White-cream flowers appear in June-July in round umbels on stalks that diverge at the end of the stems; they are followed by purplish black fruits resembling a bit the elder fruits (hence the other popular name: dwarf elder). The inflorescences stalks become red, making a nice contrast with the black fruits towards the fall. But enough talk, the pictures are always more convincing…

Not to be confounded with Sarsaparilla – the common name used for various species of Smilax (greenbriers), more particularly for Smilax regelii.

And then there were the Saxifrages…

Gardens, Plant portraits, Propagation

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’

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 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.

Saxifraga ‘Athena’

Saxifraga cochlearis ‘Minor’

Saxifraga oppositifolia ‘Florissa’

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).

Saxifraga ‘Allendale Charm’

Saxifraga oppositifolia ‘Theodor’

Saxifraga ‘Premsyl Orac’

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.

Saxifraga ‘Penelope’

Saxifraga ex. Porteous

Saxifraga ‘Jana’

Saxifraga ‘Dana’

And of course, I came home with my ‘Romeo’ (and a carload of tufa stones), hope our romance will last a bit longer…

Saxifraga ‘Romeo’

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.
