Leptarrhena pyrolifolia seeds: light brown, fusiform and partially ribbed with long tails at both ends.

I first wrote a very short post on Leptarrhena pyrolifolia seeds in 2018, after receiving a small package of seeds from a friend. I was wondering that time about the particular shape of the seeds, different than any other seeds of the Saxifragaceae family I’ve seen.

In a way it makes sense, Leptarrhena pyrolifolia (Leatherleaf saxifrage) is the only species of its genus. The name comes from: Greek leptos, slender, and arrhen, male, alluding to stamen filaments (FNA).

So, seeds-wise I knew what to expect when I had the chance to see it for the first time last summer during a trip to BC. What I didn’t expect was how much more handsome this species is in reality, more than pictures can show. It often happens, nothing beats seeing a plant in ‘situ’ among its companions.

Leptarrhena pyrolifolia is a cold hardy, evergreen perennial plant species that inhabiting wet meadows and wet cliffs, usually found around stream banks and seepage areas. It grows in mountaineous areas of AB, BC, NWT and Yukon (Canada) and the US.

The Leatherleaf saxifrage grows from a rhizome and like the common name implies, it has attractive, leathery, shiny and toothed leaves, similar in shape and texture to those of most Pyrola species.
From the compact carpet of glossy leaves, arises a tall flowering stem up to 25-30 cm bearing clusters of white/pinkish flowers in mid-summer. Easy to observe later are the conspicuous red fruits, a very nice addition to the overall aspect of the plant (the red capsules resemble a lot those of Triantha glutinosa, another moisture loving plant).

I wonder why this species is not more widespread into cultivation, especially considering that it has evergreen foliage and it is a very cold hardy species; qualities that those living in cold climates always appreciate in a plant.

Maybe we can change this situation. Why not consider going beyond the more ‘regular’ saxifrages and also grow Leptarrrhena? It will do well in a slightly moist place, in the rockery or elsewhere in the garden, with other moisture loving species like for example: Zigadenus, Lobelia cardinalis, Gentiana andrewsii, Primulas, Silene pusilla, various sedges….. Due to its rhizomatous nature, it can be used as a small scale, evergreen groundcover.

It is a bit late to sow species requiring cold/moist stratification (unless provide stratification in the fridge), but I have it on my list for next year. For now I will give it a try with GA3 as soon as I ‘turn on the lights’ just to see how it goes.

*There are reports of medicinal usage of Leptarrhena among the Aleuts of Alaska and Indigenous People of British Columbia, most commonly applying a poultice of chewed leaves to wounds.
So, keep this in mind, you never know when the leatherleaf saxifrage will come in handy :)

We are all tired of the extreme cold and cleaning snow by now and dreaming of greens and other colors. When selecting a few spring pictures for a short garden walk to enjoy bright, warm colors I stumbled upon the cheerful flowers of Chrysogonum virginianum Norman Singer’s form.

Chrysogonum virginianum Norman Singer form

It is a good occasion to spread the joy about Chrysogonum virginianum (green and gold, goldenstar), particularly about the Norman Singer form, which was named after a North American Rock Garden Society founding member (nowadays remarketed as Chrysogonum virginianum ‘Superstar’).
You can read an excellent plant portrait on the Ontario Rock Garden Society website, by Robert Pavlis, from whom I also received a division few years ago:
https://onrockgarden.com/index.php/plant-of-the-month?view=article&id=88:chrysogonum-virginianum-norman-singer&catid=22

I have nothing much to add to the plant portrait, except for the fact of being indeed an excellent  low-growing, mat forming plant that every garden should have! You won’t know until you try it.

Almost evergreen, with large, bright yellow flowers (reblooming sometimes), Chrysogonum virginianum Norman Singer form is one of the best edging/groundcovering  species for a sunny to part-shade location. Mat forming doesn’t have a bad connotation in this case, because the rhizomes are short and it grows very compact. I even had a division growing in a full shade location for a while, just that it didn’t flower so well.

Join the ORG&HP Society and participate in the Spring plant sale, maybe you’ll get lucky and find a division for yourself!

Degenia velebitica

A question on everyone’s mind is how will some of our plants fare through this low temperatures period? Most will be OK, it is not the first time it’s been so cold in this region (after all we are zone 5).

More damaging than the cold are the winter rain periods of which we got quite a few in December; so I worry more about some of the rockery plants, like the young Degenia velebitica shown here, which require excellent drainage and ideally would spend the whole winter under snow. We’ll have to wait for spring to see the results.

 

Until then, a few green and golds and other spring warm colors.

 

Winter has arrived and with it a bit more time to look after a few postponed seeds. There were a couple of wild collected Antennaria species put ‘on hold’ for good reason. They are difficult to identify, sometimes even specialists may encounter problems because of the widespread polyploidy and apomixy among them.

Erythranthe lewisii

Most Antennaria species are excellent plants for rockeries, especially due to their silvery foliage and we cannot pass the occasion growing them from wild collected seeds when they are available.

A third species put on hold until I was sure how many seeds can be offered was Erythranthe lewisii. Lewis Monketflower or Pink monkey-flower (syn. Mimulus lewisii), is a showy inhabitant of moist streambanks, seepage areas and avalanche tracks of the montane and lower alpine zones.

All species can be found in the Seed List now.

Antennaria rosea spp. pulvinata

The first Antennaria was found in a meadow at the edge of the woods along the Bow Valley in the Banff area. The silvery foliage forms mats at the ground level (see the gallery) and the flowering stems are up to about 15 cm.  After looking over various details many times, I may stand to be corrected, but all characters of the mother-plants fit in with the A. rosea group. The subspecies has been assigned considering the collection place: Antennaria rosea ssp. pulvinata.

Plants under the name of Antennaria rosea can differ morphologically because it has a wide distribution and grows in a variety of habitats. For this reason, it is best to keep in your records the collection place.

The second Antennaria species from which I collected a few seeds at a much higher altitude is Antennaria lanata, woolly pussytoes. This species belongs to the pussytoes group with erect, longer leaves, together with A. pulcherrima and A. anaphaloides.

Antennaria lanata, woolly pussytoes

It was seen in various locations, in the company of Cassiope and Luetkea pectinata, which suggests the need for an acidic substrate. Factoring in the elevation, meaning a thick layer of snow present until late spring followed by plenty of moisture, makes this species less compatible with the hot & super dry summers of SW Ontario (this will not stop me from trying it out!).

More pictures showing companion species are presented in the gallery below.

By tradition, I always sow on Dec. 1st part of the species in need of cold/moist stratification; this time the pussytoes and some of their companions.

Those who are preparing to do the same, please review this post where I briefly outlined why sowing in late Nov/December it is different than sowing in September and how to handle the sowings: Practical advice for sowing in the winter.

Pictures taken in the wild will sometimes not catch the plants at their best time, but we can always draw inspiration for our gardens from them, especially by noticing the companion species growing in the same place.

Latest native species added to the Seeds List: from the well-known by now Asclepias exaltata to new donations from friends, always thankful for them:
Rudbeckia maxima, Giant coneflower
Phytolacca americana ‘Variegata’, Variegated pokeweed
and Musineon divaricatum, Leafy wild parsley

I had somewhere an older picture with Rudbeckia maxima but cannot find it. If we look on google images here: Rudbeckia maxima, we see an extremely tall Black-eyes Susan, with a particular large, glaucous foliage; a truly striking species.
Musineon divaricatum, leafy wild parsley was a completely new species to me. What better occasion to learn about new plants than through their seeds?! We are always in need of hardy, drought resistant species for our gardens.

Everyone knows Phytolacca americana, the American pokeweed. It also has a variegated form, with creamy splashed foliage which adds more interest and provides a nice background for the black fruits in the fall. Back again to google images, which most times are useful: Phytolacca americana ‘Variegata’.

However, it was disturbing to see that if someone looks on google after typing Phytolacca americana, there are a LOT of wrongly identified fruits images, coming from all sides of the life: seeds sellers, images sellers, food bloggers… you name it.

Phytolacca acinosa, Chinese pokeweed

We can look at our American pokeweed as an ornamental plant, and also, as its common name implies, a weed (outside of North America). On the fact that is a native species, we accept that will reseed around and maybe spread in undesirable places, as it happens with Solidago canadensis.

However, we always have to be aware of ‘impersonators’ of the same genus which have different origins. In our regions they can easily become invasive weeds. This is not the case yet for the Chinese and Indian Phytolacca species, but we have to be cautious with all species producing abundant fruits & reseeding around easily.

Phytolacca acinosa, a Chinese species, is morphologically very similar to the native Phytolacca americana. The most visible differences are the erect inflorescences and the fruits.
In Phytolacca acinosa the carpels are free, and thus the fruit looks deeply furrowed when ripe; the seeds are reniform, ca. 3 mm, 3-angulate and smooth.

In Phytolacca americana, the carpels are fused, and therefore the fruits are round berries (at maturity) with the seeds lenticular, about the same size, black and shiny. Go Botany (https://gobotany.nativeplanttrust.org/) is a website that you can always trust to provide true images for NA native species.

Phytolacca americana shown on Go Botany website

The differences in fruits between P. americana and P. acinosa (and probably others) are very easy to observe in my opinion. Negligence, copy-paste from one site to another without discernment may be the cause of so many mistakes.

I don’t have the intention to openly bash other websites, but mistakes have to be shown in order to learn from them.
Open and browse the gallery where I give just a few examples and notice the label ‘wrong’, meaning ‘not Phytolacca americana’ (probably P. acinosa or P. polyandra?).

The conclusion is: google images for plants is usually useful, gathering info from many educational or other purposes websites, but never take for ‘true’ everything you see. Try to do more research and, in general, be cautious about websites that try to sell you something.

Probably the last call (!) for the moist packed seeds; we have again a window of opportunity for shipping, but it won’t last long.

New seeds in stock for today: Hamamelis virginiana,Viburnum lentago (Nannyberry), plus a replenished stock for Triosteum aurantiacum. They can be grown together in the garden as they enjoy similar conditions.

For those unfamiliar with it, a Hamamelis virginiana plant portrait follows next, with the emphasis on a very cool method of seeds dispersal. You can still find the American witch-hazels in flower in the woods, and who knows, maybe even witness a few ‘flying’ seeds!
Having a late October flowering species it is a real treat for the cold climate of Eastern Canada (and not only). It is not a ‘mistake’, it happens every year. The bright yellow flowers with a spicy fragrance that adorn the usual bare branches are very visible at this time of year.

In addition to the odd flowering time, the fruit maturation is also unusual: woody capsules develop over many months into the next year, and then explosively expel two shiny seeds at the same time with the new blooming. The genus name Hamamelis is actually a reference to this, meaning “at the same time” (flowering) and “fruit”.

It is said that the seeds can be expelled at up to 6-10 m distance! This method of seed dispersal reflects another, rarely employed common name: snapping hazelnut. Even more, the seeds spin during their ‘flight’!

This dispersal of seeds is similar for all Hamamelis species (4 of them), and the phenomenon has received a lot of attention. Scientists believe that it could inspire/improve the design of mechanisms for jumping robots. Watch and read the explanations of this cool video recorded by a team from Duke University: https://www.youtube.com/watch?v=dv0ltUBe_UE

While approaching a group of witch-hazels to smell the flowers last week, I noticed some capsules slightly opened and just showing the seeds.

I collected a few, how to abstain?! I never had the chance before. At home, I placed them in a paper bag, and then popping sounds were heard over the next few days. You can just relax and wait for the seeds to ‘liberate’ themselves in the bag. How nice, compared to cleaning Viburnum seeds!

Hamamelis virginiana leaves are similar in shape to those of European Corylus, the hazelnut, and this combined with the fact that Early European settles observed that Indigenous People used its forked branches to find underground water sources (dowsing), lead to the common name of witch-hazel. It seems that the early name was actually Wicke Hazel (meaning pliant in Old English), and only later it became witch-hazel, although it has nothing to do with the witches :)

American witch-hazel has had long medicinal usage among the Indigenous People, with the bark and leaves being used for insect bites, minor burns, skin irritation, colds and fevers; the astringent extract of witch-hazel is still present on the drugstores shelves.

 A nice small tree with a vase shape, suitable for part-shaded to sun locations (better flowering), and quite adaptable to substrates, with the exception of those too dry. Besides the late fall flowering, the foliage will also take a nice golden hue in the fall. It is less cultivated than the more colorful Asian Hamamelis species/hybrids available on the market, but I think we should give it more attention. After all, how many species do we have in our cold climate to flower in October?!

Propagation by seeds
The seeds require alternate cycles of warm followed by cold for germination. Considering they have just been harvested, if we sow in outdoor pots in late fall/winter, it means they will germinate in the second year after sowing. Or we can try cycles of moist stratification in plastic bags, or – even better, sow the seeds in late spring/summer and let it all happen naturally!

 

The seeds announcement of today come in pairs.
Two species for dry, sunny areas:
Oenothera macrocarpa (Missouri evening primrose) and Astragalus missouriensis (Missouri milkvetch).
A pair for moist locations:
Nabalus racemosus and Smilax tamnoides (Bristly greenbriar).

Smilax tamnoides seeds

I’ll take this occasion to present Nabalus racemosus (aka Prenanthes racemosa, Rattlesnake root) which is rarely cultivated in the gardens, or maybe not at all.

All others are shortly described in the Shop and some may be discussed at a later time. On the account of Friday’s seeds we’ll have only a picture with the handsome seeds of Smilax tamnoides.

Nabalus racemosus plant portrait

I fell in love with the Rattlesnake root after seeing in flower one year in early fall in Bruce peninsula. From this point of view, Rattlesnake root is a good common name!

The fuzzy buds and pink flowers somehow are very attractive. One year, many monarchs were literally ‘hanging’ on the flowering stems in a group of plants, and so I became even more interested in growing it.

The common name Rattlesnake root suggests that it was used as a remedy for snakebites by the Indigenous People, and other common maladies like fever, headaches and dysentery.

I managed to grow a couple of plants just from a few seeds. It is not difficult to germinate, it only requires a long period of cold/moist stratification, ie. sow in late fall outdoors.

Nabalus racemosus (Fam. Asteraceae) is a moisture loving, tall species. Depending on how moist the place is, it can reach over 1.60 m on moist substrates, or remain around 80 cm on dryish soils.
In the wild, it can be found growing around stream banks, temporarily wet shorelines, and moist woodland edges.

Nabalus racemosus, Rattlesnake root, flowering in the garden

In the garden will share the location with Lobelia siphilitica, Iris versicolor, Lobelia cardinalis, Eupatorium perfoliatum, Castilleja coccinea and other similar companions.

The sturdy flowering stem grows from a rosette of large, glaucous leaves, tightly packed first with clusters of hairy buds, which open to pink flowers with the outer phyllaries covered in dense hairs.

The blooming time is August-September, and the flowers are visited by many late summer pollinators: butterflies, bumblebees and everyone else that would enjoy a sip of nectar.

Overall, Rattlesnake root is not a plant for the front of the border, or for those in need of very tidy garden beds. If you are wild at heart though and have a slightly moist garden area/where the water collects seasonally, go for it, you won’t regret it.

What’s next? Hamamelis virginiana, Viburnum rafinesquianum, Triosteum aurantiacum, a couple of Polemoniums…

We arrived at the last offering of moist packed seeds of the season: Eastern skunk cabbage seeds, Symplocarpus foetidus.

The muddy affair of extracting the skunk cabbage seeds from the fruits.

They have been missing from the Seeds list in the last couple of years, so despite the not-so-pleasant process of cleaning/processing of these seeds, a couple of fruits have been collected. They blend in very well with the woodland floor and most times are difficult to spot.

For those who want to do it themselves, after various trials, the best method to extract the seeds from the fruits is to have them sitting in a Ziploc bag for a while until they soften naturally; mush the whole content very well afterwards, select the seeds from the ‘muddy affair’, and then rinse them well.

Sow right away, or pack them with a moist media for later sowing, but before the winter arrives.
The seeds will also start germinating in a Ziploc bag with wet media after cold stratification, but the roots do not develop as good as when they germinate in a pot (make it a tall one) or when sown directly in the ground.

More about Symplocarpus foetidus (skunk cabbage) here: An after Easter portrait.

And, this is not really the last call for all others moist-packed seeds in stock, but with the cold weather fast approaching we are getting close to it!
Trillium grandiflorum, Uvularia grandiflora, Podophyllum peltatum, Asarum canadense and few others are still available; for easy finding the moist packed seeds offerings are green-written in the Seeds List.

Other species to be announced next week.
(For those who like to plan for their orders, NA natives: Nabalus racemosus (Prenanthes), Oenothera macrocarpa, Smilax tamnoides and maybe Euthamia graminifolia).

More seeds! More seeds from me and friends; and there will be more as soon as they get cleaned and the website files prepared.

For now, we can enjoy again Amphicarpaea bracteata, Groundhog peanut. Due to the last year’s drought, there was a break on seeds. By chance, I discovered that they enjoy climbing up bamboo sticks. So, those who want to avoid having them scrambling up nearby plants, there is an easy trick to do: put a few sticks around where the plants grow. The flowering and seeds production (not the peanuts!) are always better on the aerial stems.

Also, after a break of a few years we can consider new for the Seed list: Ptelea trifoliata, the Hop tree and the Northern bayberry Myrica pensylvanica.

For those on the look for something drought resistant with bright, red/magenta flowers, Callirhoe digitata seeds are also awaiting in the SEEDs List.

 

I should have had Houstonia canadensis seeds announced ‘officially’ together with Lobelia kalmii; only that it takes more time to process some fruits to see how many seeds will be available.
In the Friday’s Seeds topic idea, we also have a picture with Houstonia fruits and seeds. The fruits are small, hard, dehiscent capsules which contain tiny, black seeds.

Similar in look when in flower to the previously offered H. longifolia, in Houstonia canadensis the basal, rosette leaves are usually pubescent above and with ciliate margins (Flora of Michigan); in fact the species is reported as being variable in the shape of the leaves and in the amount of pubescence. In H. longifolia the leaves are glabrous. If not for taking the close up picture when attracted by the beautiful foliage changing color, it would have been impossible to identify it. It is always good to take the time for close-up pictures.

You can grow the Canada Summer bluet together with few of its wild companions, like: Lobelia kalmii, Campanula rotundifolia, Solidago simplex var. ontarioense, Primula mistassinica, Prunus pumila and Clinopodium arkansanum.

Even if some of these species grow in alvars, they adapt well to garden growing conditions, on any limestone/calcareous substrate. So far, I would say that only an acidic substrate will pose a problem when growing these species. I grow them all, in various garden locations and instead of Canada Summer Bluet I have H. longifolia.

They all enjoy a full to part-sun, moist towards dry location, which is moist at least seasonally.
You can use the edge of a border/rockery that gets more moisture after snowmelt, when it rains heavily, or where the water gathers naturally due to the ground gradient.

And, because many of these species have fine seeds which require superficial sowing, a picture with Primula mistassinica seedlings with explanations.

Primula mistassinica seedlings, a couple of Castilleja miniata seedlings can be seen to the right

The seeds were sown on top of the substrate in late fall (2022) in a larger pot (together with few other species with fine seeds that require superficial sowing) and covered with very fine gravel to prevent washing out. The pot has stayed outdoors over the winter; in early spring a thick layer of ice had formed on top of it and during melting moved around some of the seeds (lesson learned – remove part of the snow in late winter/early spring).

Lobelia kalmii, Campanula rotundifolia which are now planted in the garden were obtained in the same way. You can use the same method and sow a few similar species with fine seeds together in a larger container and then gradually transplant the seedlings when they grow up. Or, keep the sowing container as it is!

You can find all these species in the SEEDs List.

Moist seeds speaking, Caulophyllum thalictroides inventory has been replenished. I know it seems there is a lot of time left until the temperatures will start to plunge, but there are other things to take into consideration, like some seeds starting to germinate (Asarum seeds emerge their radicles at some point in November) or being sold out (Medeola virginiana, Trillium flexipes).

Dry seeds speaking, the inventory has been replenished for:
Campanula rotundifolia (still flowering, on-going collection)
Drosera linearis
Pinguicula vulgaris and
Primula mistassinica

For those who like to plan their orders, next to follow next week from the native species side: Houstonia canadensis, Clinopodum arkansanum, Gillenia trifoliata and maybe Delphinium exaltatum. Stay tuned…

Lobelia kalmii, Kalm’s Lobelia

And a short plant portrait for a new offering – Lobelia kalmii, Kalm’s Lobelia

A bit similar in look to the previously offered Lobelia spicata, Lobelia kalmii is a small size, floriferous and delicate looking plant with blue/lavender flowers that can be found in moist places such as sandy, gravely meadows, fens, tamarack (larix) swamps. It is also common growing in rock crevices and among boulders on the rocky shores of Lake Huron.

Looks like a perfect species to incorporate in the moist side of a rockery, or any other slightly moist garden location (edge of a border, ponds, waterfalls….). It may be delicate looking, just like Campanula rotundifolia, but perfectly cold hardy.

It is easy to grow from seeds and flowering in the second year after sowing in my garden. I just kept the seedlings with too much shade and they got elongated, but otherwise it is an easy going species (beware acidic substrates though).

The species and common names honor Pehr (Peter) Kalm, a Swedish-Finnish botanist, explorer and naturalist, student of Carl Linnaeus, who undertook the exploration of Northern N. American regions around 1748. Linnaeus will cite Kalm for about 90 species, many of them new, also naming the genus Kalmia in his honor.

At the end of the season, it is difficult to differentiate L. kalmii from L. spicata when they are found growing in the same locations. I suspect that last year, at least part of the seeds offered as L. spicata were from L. kalmii, so those who purchased seeds please get in touch to learn how to differentiate them after flowering: Contact form

Many thanks to all customers who are placing orders at this time!
Due to the on-going seeds collecting and updating of the inventory, the shipping of the orders may be a bit slower than usual. Also, while I appreciate the enthusiasm, please keep the orders short for now; focus on the moist packed species category, Helleborus, Aralia, and all others that require immediate sowing.

For customers new to growing from seeds, especially moist-packed species, please review: FAQ – moist packed seeds.
And don’t forget to read various articles from the Germination page.

Latest seeds collected:
Caulophyllum thalictroides, which has been shown so many times, and the germination discussed at length; the inventory will be replenished next  week.

Also, two species that require first a bit of double checking before becoming available: Houstonia canadensis, Canada summer bluets and Lobelia kalmii, Kalm’s Lobelia.

In late summer we can always admire various native Lobelia species, both in the garden and wild areas. Not only they are colorful and beautiful, they are also invaluable for all pollinators. There is no rush to purchase the seeds tough; they require a moist/cold stratification – i.e. sowing to be done in late fall/early winter.

For plant collectors, the Podophyllum name sparks instantly the ‘rare plants’ lust. Like with the Arisaema species, unfortunately the North American continent wasn’t left with much: only one Podophyllum species, the Mayapple, Podophyllum peltatum. It is a wonderful wildflower with personality which will slowly form a colony in suitable conditions in the forests/ or woodland garden.

Podophyllum peltatum erupting from the ground in early spring

The genus name comes from the Greek ‘anapodophyllum’ meaning a leaf like the foot (podos) of a duck (anas) and peltatum – refers to the specific attachment of the leaf stalk near the center of the leaf blade.

Mayapples can be found in deciduous forests, both in bottomlands and on drier sites. Large colonies usually develop in places with more moisture. Although they can grow in dry places, underneath the trees, in very dry years, they can go dormant in early fall. Some of its companion plants are: Sanguinaria canadensis, Caulophyllum thalictroides, Trillium grandiflorum, Uvularia grandiflora….

Mayapples emerge in early spring with a couple of tightly closed leaves, which expand umbrella-like afterwards and cover one solitary, white, waxy flower somewhere in May; if pollinaton was successful,  ‘green apples’ will form. Unfortunately, the frequency of successful pollination is not high in Mayapple flowers, even if various pollinators visit the flowers.

Therefore, the fruit set rates are often low for individual colonies of plants, and even more, I have noticed that in years with drought most fruits are aborted. The ripe fruits are the only part of the plant that’s not toxic, and are called “hog apples” or “wild lemons”. They become yellow and fragrant when fully ripe, usually in mid to late August (no idea why the ‘mayapple’ name). They are enjoyed by a variety of small animals, which are also the principal seed dispersers (the Eastern box turtle, gray squirrels, opossum, raccoons…).
So yes, Mayapple’s ripe fruits are edible, and you can even find recipes for jellies.

Medicinal importance

Even if the whole plant, except mature fruits, contains toxic substances, the Mayapple has also been a staple medicinal plant in the repertoire of the Indigenous Peoples, being used as: boiled roots (laxative), juice of the fresh rhizome (to improve hearing), powdered root (skin ulcers and sores, purgative), to mention just the well-known uses.
At some point, the Mayapple resin (extracted from the rhizome) was considered one the most powerful laxatives available, and it was even sold commercially (Carter’s Little Liver Pills in early 1900s), but because of the toxicity, this use has been discontinued.

More recently, pharmaceutical research proved that certain chemical constituents of the Podophyllum species can be used as anticancer agents. The substance responsible is called podophyllin and it is a resin contained in the rhizome (see the use of powder root to treat skin ulcers). This resin is composed of several toxic glycosides, the most active being podophyllotoxin. Derivatives of the podophyllotoxin (etoposide and teniposide) were formulated into anticancer drugs used in chemotherapy to inhibit the growth of tumors in various types of cancer.

 Propagation

Actually, all Podophyllum species are very easy to cultivate – all you need is shade…and seeds or rhizomes cuttings. You can read a detailed account for growing Mayapple from seeds here:  Growing Podophyllum from seeds.
It is not difficult if you follow the directions. Mayapple seeds need to be sown fresh, if not moist packed, in order to obtain good germination. Be aware of companies selling dry kept seeds!!!

Podophyllum peltatum first year seedlings with cotyledon leaves in 2018; these are grown up by now and flowering!

Patience is required like with all other rhizomatous species, which are slow to develop in the first years. From seeds they will flower in 5-6 years.

As a side note, the seeds are enclosed in a sticky, mucilaginous mass, and are the most awful seeds to clean out! Ask everyone who has ever done it!

In dry years, the few formed fruits are aborted and offered seeds are quite rare, or available in tiny amounts. So, take advantage of this wet season when more fruits have been produced if you want to grow a few umbrellas in your woodland garden.

 

The Seeds Shop will open for orders next Monday, Aug. 28th – watch for the announcement and please do not order before!

 

 

A short plant portrait for Delphinium exaltatum today. Besides getting familiar with this Eastern North American larkspur, I want to emphasize the fact that for species starting to flower late in July or August, like all fall Gentian for example, seeds MAY become available only in very late fall October or even November.

The early fall Seeds List is taking shape and it may ready at the end of next week, fingers crossed; if not, by 1st of September. It will be announced.

Delphinium exaltatum, Tall larkspur

Delphinium exaltatum, shown here cultivated in the garden, is a native species with a rather limited distribution in a few Eastern US states. My plant was grown from seeds that were offered a few years ago in the shop, so other people should also have it in their gardens.

 It goes by the common name of Tall larkspur and the epithet ‘exaltatum’ also alludes to its height.
The leaves are palmate-lobed with narrow lobes, and the flowering stems can reach 1.6+ m, also depending on the growing conditions.

The lavender-blue flowers open gradually on loose, branched inflorescences in late summer, reason why it has a very long blooming period. They become the center of attention for various pollinators; particularly butterflies and the hummingbirds are in love with it.

It is said to dislike hot and humid conditions. For this reason in regions with hot summers (like SW Ontario) it does better in a part-shaded location with extra moisture. Otherwise a full sun location can be used. It may need staking, although I prefer to let mine to sway in the breeze.

Among other noticeable plants flowering in late summer, besides all the Echinacea, Rudbeckia and Eupatoriums, are various Gentians: Gentiana septemfida towards the end of flowering, Gentiana paradoxa just starting, Iris dichotoma,  Platycodon, Lomelosia olgae, Ziziphora clinopodioides…

As previously announced, starting tomorrow we won’t accept new orders – until further notice (late Aug./September), depending on how the collecting of seeds goes. Many thanks to all who placed orders for those species that need an early summer sowing.

On and off rainy days are making difficult the collection of seeds. Taking pictures is also not an easy task, but after two years of drought it is a relief to see the lush vegetation both in the wild habitats and also in the garden.

Lilium michiganense is in flower, both in the woods and in my garden. Probably one of the easiest lily to grow from seeds, so do not hesitate to give it a try. Few other native species flowering now or about to do so in the garden: Deschampsia cespitosa, Symphyotrichum laeve, Zigadenus elegans ssp. glaucus, Asclepias tuberosa (in part-shade), Campanula rotundifolia, Campanulastrum americanum, Eupatorium perfoliatum, Clinopodium arkansanum; Lobelia siphilitica and Lobelia cardinalis clumps are promising an exceptional late summer flower show.

All, except Deschampsia (tufted hairgrass) were grown from seeds. It is possible to introduce quite a large numbers of native species in your garden to flower from spring until late fall, without breaking the bank. Problem is in fact, that many are not readily available from garden centers.
Try to grow them from seeds. BotanyCa will strive to provide :-)

Enjoy the rest of the summer, hike often in the woods, be observant of the plants and all other species, and try to learn more about them. I’ll post updates once in a while about collected seeds – in the featured image: recently collected fruits of Aralia nudicaulis (wild sarsaparilla).

* Canada Post enjoys an extended Canada Day holiday; all orders received will be prepared and ready for shipping on and after July 4th.

Sanguinaria canadensis (bloodroot), first seeds of 2023

It is already mid-June, wow! This is the time when various spring flowering species start to mature their seeds; soon there will be a wave of native species seeds one after another starting with Sanguinaria canadensis, Asarum canadense, Stylophorum diphyllum, and Jeffersonia diphylla…to mention just a few.

Various other species mature their fruits gradually, and also the collecting is done in the same way. For most Viola species, Silene pusilla, Saxifraga cuneifolia, Capnoides sempervirens…this involves seeds collecting every day now. Plus, Helleborus caucasicus seeds are being captured by organza bags, and others will follow shortly.

As soon as there is a larger batch of species collected, there will be another call for seeds, probably in late June – stay tuned.

The regulars of June garden are in flower now: Dictamnus albus, Baptisia australis, Clematis integrifolia, various Dianthus, Salvia, Aconitum moldavicum, with Asphodeline lutea in top bloom. While we all rejoiced in few rainy days, it was not very inducing for taking many new pictures. There are also new garden friends this year, like Glaucium aurantiacum and Gladiolus tenuis.

This is also a good time for planting 2 years-old seedlings of various bulbous species in the ground, as they enter their summer rest period.

Erythronium sibiricum 2 years-old tubers before planting in the ground

Species like Corydalis solida and allies, Erythronium, Fritillaria, Adonis, Crocus species, Galanthus…you can plant them in the ground after the second year of growth. They can also be grown further in pots, but honestly, I have obtained better results for  such species with this method then by growing them longer in pots. The Canadian plant trade is lacking diversity for these species, so what can we do?

We grow from seeds!
