Wildflowers Monday – Hydrophyllum virginianum
Plant portraits, Wildflowers of North AmericaIt’s in the details
Conspicuously silver-marked, pinnate leaves which are among the first to appear early in the spring:
Hydrophyllum virginianum – early spring foliage
Curled flower buds with ciliate calyces which resemble an exquisite lace work; opening to reveal white or purple bell-shaped flowers with exerted stamens:
Hydrophyllum virginianum flowers
…recognized by pollination ecologists as very valuable because they attract large numbers of native bees. They must be delicious – often foraged by the bumblebees long after their prime:
Bumblebee on Hydrophyllum virginianum
Hydrophyllum virginianum grows very well in dry, shade conditions of hardwood forests, bottomlands and edges of the woods. Excellent as a groundcover in difficult shady areas and for naturalization projects. Although considered a bit weedy, I noticed that it is not capable to compete with the non-native invasive species, which are spreading in the remnants woodlots between newly developed residential areas.
Another Hydrophyllum that will save your time (and back) from weeding in the shady, moist areas of the garden, is the Broad-leaf waterleaf – Hydrophyllum canadense.
Hydrophyllum canadense
Wildflowers Monday – Jeffersonia diphylla
Wildflowers of North AmericaJeffersonia diphylla – Twinleaf, Rheumatism root (Fam. Berberidaceae)
Twinleaf is quite an unusual North American native species. Not often cultivated and we still have to find it in the woods of Southwestern Ontario where it is probably quite rare. This gorgeous picture belongs to a cultivated plant. It is obviously thriving in a garden where many native species are mingling happily in a fine balance with more exotic species (many thanks for the opportunity to take the pictures).
Jeffersonia diphylla
It is easily distinguished by the bluish-green two-lobed leaves that gave both its Latin and common names. Think of them as green butterflies topped up in the spring by large white flowers resembling those of the bloodroot (Sanguinaria canadensis). Awesome combination!
But the flowering is a short event like in many other cases; it is the foliage that makes it so special. In the spring, the newly emerged stems are purple coloured, reminding of another great perennial of Berberidaceae, the blue cohosh. A definitely show off for any garden! If we would be to say this is a rare Chinese species, would it become more desirable? Joke apart, the only other Jeffersonia species, equally special, J. dubia, grows wild in the Far East Russia, North Korea, and Manchuria.
Named in honour of US President Thomas Jefferson, which was a keen gardener himself, it has had medicinal uses in the traditional aboriginal medicine, mainly for dropsy, urinary problems and inflammations (hence the name rheumatism root).
Jeffersonia diphylla fruit
Propagation: not difficult from seeds if they are kept moist at all times and allowed a warm-cold cycle (just like its cousins Epimediums). It will germinate in the next warm cycle. Not fast growing but worthwhile the wait. It presents a peculiar capsule that opens from a slit below the top, similar with a lid (be careful to catch the arilate seeds!)
Wildflowers Monday – Pink and green Trillium
Photography, Wildflowers of North AmericaWandering in the woods through masses of white trillium (T. grandiflorum) at peak flowering is a privilege.
An even greater and exciting treat is finding its pink form – Trillium grandiflorum f. roseum and interesting green variants. The pink flower form can be usually found mixed in large populations of ‘normal’ white trilliums. Scouting for them has to be done early because later almost all of the “whites” will also turn slightly pink when fading.
Trillium grandiflorum f. roseum
The greening of the White Trillium flowers is believed to be caused by infection with a pathogen belonging to the genus Phytoplasma. Phytoplasmic infections are usually confined to phloem and often result in the transformation of floral parts to leafy green structures, potentially leading to sterility of the plant. But there is more research to be done until all will be clear regarding this subject.
Trillium grandiflorum – green variant No.1
Trillium grandiflorum – green variant No. 2; I think ‘Green Feather’ would be a good name for it…
Trillium grandiflorum – the No.3 green variant, arising from a carpet of wild-ginger leaves
I can only watch closely my variants to see how they evolve and if they’ll form fruits/seeds. There is something beautiful about their ‘infection’ ;) At least the No.3 looks very happy and thriving.
Earth octopus
PropagationYesterday I spent quite some time into the darkness of the garage, doing archaeological plant-digging in containers. I was looking after various creatures that like to spend the winter dry and need to be unearthed by late April and be brought back to life (if possible).
A large earth octopus almost jumped out of a pot! Luckily it proved out to be a gentle one. I checked its legs one by one, all seemed to be fine; eyes wide open and smiling. It was carefully placed in fresh, rich potting mix as it likes it, free to swim and have fun.
The earth octopus (Roscoea auriculata)
I’ll wait with the water until it starts growing a bit (it’s an earth octopus with rhizomatous fleshy tentacles after all). Somewhere in mid-summer a strange phenomenon will happen: the earth octopus will bloom!
Roscoea auriculata it is a hardy ginger from Nepal, Sikkim and Bhutan, where it grows in grasslands at 2400-2700 m altitude. As the name suggests, it has consistently auriculate (eared) leaves on the pseudostem. The height can be variable 20-40 cm and the flowers are large, in various shades of purple to deep violet or even white. It can be mistaken with R. purpurea but it flowers a bit earlier and the flowers have usually white upper staminodes and a strongly down-facing labellum.There were also a few baby octopuses (not completely developed, some have only 2-3 tentacles), all fine looking and ready to start earth swimming. Roscoeas are very pleasant plants to grow from seeds; it will take 3+ years for the first flowers to appear.
Spring startups
Gardens, Propagation, Wildflowers of North AmericaNew growths, new beginnings – All equally exciting!
Caulophyllum thalictroides first germinated seeds:
Caulophyllum thalictroides germination startup
The beginning of a ‘direct woodland sowing’ project (native species, of course)– more about this will be detailed soon.
The spotting of a few happy pollinators (alas not in my garden):
The first day out at ‘fresh air’ for the young seedlings:
Warm lilies
Propagation, Wildflowers of North AmericaLilium michiganense, Lilium canadense (plus few others) are the kind of lilies that require warmth for the first stage of germination (about 20˚C), and then a period of cold (0-5˚C for 2-3 months) for the true leaves to emerge. If you get these seeds in late fall or winter, this is the tried recipe to make sure that they’ll start growing leaves in the spring:
Place the seeds in a Ziploc bag with moist vermiculite and keep them during the winter months (Nov/Dec.-Feb/March) at room temperature. Check the moisture once in a while. After the tiny bulblets appear, place the Ziplocs in the fridge for the cold treatment (March-May). Pot them afterwards and place outside.
These bulblets had their photos taken and now are ready to switch places in the fridge with the seeds that are coming out for sowing. Some grow out of the seed and are visible, while some can remain more or less enclosed.
And bulblets of another woodland edge growing, tall Lilium (supposedly canadense); we didn’t catch it in flower last year, but it was an impressive exemplar. It has been placed on the ‘watch list’ for this year so we can properly identify it.
Although North American native species, these Liliums and also few others are almost never grown by commercial nurseries. Start growing your own, besides being ‘hot’ plants, they are pollinated by hummingbirds, sphinx moths and butterflies like the Monarch and Spicebush Swallowtail!
Lilium michiganense
Dreams
Wildflowers of North America“Like the seeds dreaming beneath the snow your heart dreams of spring” – Kahlil Gibran
One of the coldest February months in history is about to end but it shouldn’t keep us from dreaming our hearts wishes…A gallery of spring flower seeds, which all bear elaiosomes; some are still dreaming under the snow or in my fridge, some have started to germinate.
(Click to see large size images)
The variety of elaiosome shapes and structures is simply mesmerizing when seen up-close. From barely seen in Claytonia (Spring beauty) to the ‘Mohican-style crest’ in Stylophorum (Wood poppy) and snail body-like in Sanguinaria (Bloodroot) – this is nature’s imagination at its best!
Berberidaceae seeds and embryos
Medicinal plants, PropagationUpdate: GA3 treatment makes no difference for Caulophyllum or other species like it which have immature embryos; they need to be kept moist (or sown fresh) and allowed the required warm/cold cycles, multiple times in case of Caulophyllum (2-3 years).
Speaking about the inside winter gardening, this year I am trying to use GA3 to speed up the germination of Caulophyllum thalictroides (and a few others). There would be much to say about Caulophyllum seeds, from the fact that they develop outside the ovary and have a drupe-like look, they must be kept moist at all times after collecting, to the fact that they have a tiny immature embryo (it’s very hard to see it even with a hand-lens) but a gigantic corneous endosperm…
But I am only showing my new method of treating the seeds with a GA3 solution and then placing them back in vermiculite in the same small plastic bags, instead of using moist towel/Ziploc or sowing in pots. At this point, the embryos are most likely at the torpedo stage.
I think it is a great method for medium to large size seeds and a super space saver (which is of my high interest right now). It is easy to see if/when something germinates, and I had proof that the roots can grow quite a bit on the support they get from vermiculite (in contrast to keeping the seeds in moist towels, where the new roots get entangled and are easily damaged).
If someone is curious to browse the gallery (hover for caption): sectioned seeds/embryos of Caulophyllum, Podophyllum peltatum and of Ranzania japonica, a most intriguing species from the same family as Caulophyllum (Berberidaceae). Many members of this family, which simply fascinates me, are difficult to grow from seeds: think Epimedium, Podophyllum, Jeffersonia, Vancouveria…I will be most happy to grow Ranzania – it looks like a cool hybrid plant between Glaucidium and Anemonopsis!
A few Epimedium and Jeffersonia diphylla were sown early summer last year. We’ll see about that… Update 2017 – the first seedling flowered this year!
Spring beauty awakening
Gardens, Plant portraits, Wildflowers of North AmericaOne more garage check-up before sinking into another round of low night-time temperatures. The spring beauty seeds are sprouting! – maybe they know something that we don’t? ;)
Claytonia virginica is a true ephemeral beauty, a cheer for the soul in springtime!
Claytonia virginica
Virginia spring beauty is common in southern and south-central Ontario and it flowers before the trees are leafing out. The pink (rarely white) flowers that are glistening in the spring sun are a treat after the long winter months! After setting seeds, it retreats in the soil for the rest of the season.
As a trial out, I sown a few seeds immediately after collecting, and I kept the rest in moist vermiculite (warm then cold). The seeds in moist storage have germinated in late December; the ones sown in the spring are germinating now. Note taken: the seeds can be safely offered for sale until beginning of December.
On a top list of ‘hardest seeds to collect’, Claytonia comes first. I have expected Corydalis to win the prize but it didn’t. Like everything beautiful, Claytonia has proven very difficult to handle because it flowers in succession and the fruit maturation follows the same pattern, plus the fruits are dehiscent; a nightmare! And, do I need to mention the small seeds? No wonder is not on many seeds shops lists! But, a few people were happy to find these seeds available, so my effort did pay off. Plus, now I have a few seedlings for myself. Double hit!
Claytonia virginica seedlings
Helleborus journeying
Alpine plants, Mountains, PropagationA short break from the deep freeze allowed me to unwrap and check the plant trays stored in the garage today. Anxiety was running high because I had noticed that a few species had started to germinate more than a week ago. Luckily, from under two sheets of fleece and plastic, the Helleborus seedlings showed their happy faces :)
While I had never thought of growing Helleborus from seeds until last year, this has proven to be a very fruitful and satisfying journey so far. The seeds have germinated promptly after being sown fresh during late summer; also the storage in moist vermiculite turned out to be a very good option for extending the fresh seeds offering period.
These Helleborus seedlings are descendants of mountaineer mother-plants:
Helleborus purpurascens – a native of alpine meadows and forests in the Carpathian Mts. (Romania to Hungary)
The hybrid double Helleborus seedlings have ‘blood’ of Helleborus torquatus – a species confined to mountain regions of the former Yugoslavia (Bosnia, Croatia, Hertegovina and Serbia – where natural double forms can be found). The most desirable forms have deep violet purple flowers (H. torquatus is one of the parents of the first dark flowered Helleborus hybrids).
Double Helleborus torquatus
Just starting to germinate is also Helleborus foetidus, a native of mountain regions from Central and S. Europe. In many cases, Helleborus seedlings will start to flower in the second year, which is another reason to happily continue the journey. Even if not all of them will be garden worthy, there are endless chances to obtain new forms with different flower colours or traits. It will be a long time until the melting snow will allow us to enjoy the Helleborus flowering on this frozen land; until then we can rejoice in growing seedlings!
And to keep them company under the lights there is another mountain plant, this time a peony – Paeonia mlokosewitschii (a native of the Caucasus Mts.)
Paeonia mlokosewitschii seedlings
Syneilesis punishment
Gardens, Plant portraits, PropagationAfter wasting time with the ceremony, I was punished to do my homework on the weekend – there are still seeds to be added in the catalogue…
I didn’t think at Syneilesis until someone who participated in the Helleborus seeds trade, asked if by any chance I have a few Syneilesis aconitifolia good seeds…There it was the warning! Indeed, if you read on various gardening forums, it will be confirmed; ‘seeds’ are set copiously but only a small amount are viable. Such a pity, considering it is a warm, easy germinator. Luckily, I was gifted, again :), a whole bunch of dry inflorescences and after sorting through all of them with patience, I was left with a few good ‘seeds’ (and a REALLY big pile of ‘fluff’).
Syneilesis aconitifolia, the shredded umbrella plant, is a great foliage plant usually grown in part-shade, but who also tolerates full sun. When grown in a rich, moist substrate it will spread to form a healthy clump, but don’t worry, there will always be someone wanting a small division of your plant. Personally, I like it most in the spring when new shoots are emerging from the ground, with the leaves covered in silky hairs – the equivalent of a fuzzy mayapple!
Syneilesis aconitifolia emergng in early spring
They maintain the fuzziness for a little while; then after expanding, the large, ‘shredded’ leaves will make you believe they belong to another plant! The name aconitifolia, actually suggests the resemblance with an Aconitum leaf (the deeply lobed kind). Tall flowering stems erupt in the summer bearing rather insignificant flowers.
There are also mentions of Syneilesis aconitifolia being used as a medicinal plant.
The love of winter – Pipsissewa
Medicinal plants, Wildflowers of North AmericaChimaphila from Greek: cheimon – winter, philein – to love
Pipsissewa from Cree language, meaning ‘it breaks into small pieces’
As we start looking towards the New Year, another thing becomes more obvious for those living in the northern hemisphere: winter has settled in! You absolutely have to love it; or you’ll be miserably dragging over 3+ months of hating it. Choose for yourself… Myself, I can’t wait to start new seeds experiments and to write more about the plants I love. Here’s the first one to put you in the mood of winter love ;)
Chimaphila umbellata (Pipsissewa, Prince’s pine) is another species about which I developed a mild obsession to propagate from seeds. It has showy, leathery, evergreen foliage, equally interesting pink, fragrant flowers and it grows in shady places (it has a taste for a slightly acidic soils). It would look great at the edge of the woodland garden or on the shaded side of a rockery. The dry capsules are also very ornamental and last into the next season; they contain lots of tiny, dust-like seeds (much like the Cypripediums) which are released easily when mature. The best time to try to collect them is in late fall.
The species is morphologically variable across its native range. Five or six subspecies have been recognized in the literature, depending on what source you look at; for example, the one from Ontario would be C. umbellata subsp. cisatlantica – it never gets easy…
Only the difficult propagation made it virtually non-existent in cultivation. According to some sources, Pipsissewa is a partial myco-heterotrophic plant, which means that it obtains a portion of its nutrients from parasitizing fungi that are part of mycorrhizal associations of other plants. It also forms its own mycorrhizal symbiosis with fungi. Kind of complicated…
Reportedly, it can be propagated from cuttings and from rhizome fragments but not very successfully (I presume, otherwise we would have seen it in cultivation). I don’t have the conditions to try rooting cuttings and don’t feel like uprooting plants to take rhizomes, so I’ll stick with seed germination trial-outs. Others have tried with some success stratification of fresh seeds in a mix inoculated with local soil, and the fine size of the seeds suggests that it might be a light sensitive germinator. We’ll see how it goes…
Chimaphila umbellata seeds
Interested in medicinal plants? – read more
Pipsissewa was and still is valued for its medicinal properties. Native Americans used it in their traditional medicine mainly for treating rheumatism, as well as for kidney, liver disorders (leaves), and other ailments. Scientific research has confirmed its pharmacological qualities a long time ago, and the modern therapeutic use of C. umbellata reflects the traditional indications. In short, it can be used like Arctostaphyllos uva-ursi, but its active components are more potent.
Today it is utilized in small scale modern herbal medicine, but has become the component of a proprietary formula – Eviprostat® largely used in Japan and Europe for the treatment of benign enlargement of the prostate.
If this is good news, the bad is that Chimaphila has been classified as a slow-growing perennial, sensitive to harvesting pressures, ecological disturbances, and foot traffic; also various reports have emphasized that it regenerates too slowly for regular commercial harvesting.
Perception
Medicinal plants, PropagationVermiculite from Latin ‘vermiculus’ = wormlet
The recently emerged rootlet of bloodroot seed has attached on this vermiculite particle with the same desperation a climber clings onto a rock. A place to grow on, salvation…
Sanguinaria canadensis seedling germinated in a bag with vermiculite, growing attached on a vermiculite particle
For us, it remains just an exfoliated fragment of a hydrated silicate mineral; worm-like shaped, lightweight, incombustible, compressible, sterile, with a high cation-exchange capacity…
Only very few Sanguinaria canadensis seeds have started to germinate in moist storage; this one was particularly well developed – good genes probably… The very young rhizome already shows signs of the future red coloration characteristic to Sanguinaria rhizomes.
Check and skotomorphogeneticals
Propagation, Wildflowers of North AmericaIs this a catchy name, or what?
I got into a routine to check the moist packed seeds at mid and end of the month. Remember the germinated Trilliums? Well, some got planted in pots and some remained in moist vermiculite, which is also a proper medium to easily check on them and take a few more pictures.
You can still read in many places that Trillium has a double dormancy but that was really old school thought. Here’s a LINK for something more up to date on what’s been called skotomorphogenetic growth (found in other species too). This concept defines germination as the point when the radicle/rhizome emerges from the seed and all the growth that follows represents the development of the seedling in the dark (from ‘skoto’ – dark in Greek).
Trillium grandiflorum seedling (late November) -a cute ‘skotomorphogenetic’ with a fatty, little rhizome; the cotyledons are already visible, now it needs more cooling before elongation will start. All this growth was achieved based on the energy reserves stored in the endosperm.
It makes sense. The term double dormancy puts quite a few people off from growing such species from seeds because it implies that they really take a lot of time to germinate. Furthermore, it suggests that the seeds are lying underground and nothing happens, which is not only completely false but also dangerous as you may miss providing the care that they need.
So, skotomorphogenetical it is; I just wish they would have found another name…All the other moist packed seeds are fine; in the featured image – plump, moist seeds of Paris quadrifolia (a Trillium relative, that is also called ‘double dormant’).
Note: one Trillium fruit can have both, seeds with dormant embryos and without – these will start germinating by fall if sown or moist storage provided.
The sleeping beauties
Gardens, PropagationAfter 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 ;)
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.
