Starting notes on Aconitum germination – 2018

,

Yesterday I sowed the first Aconitum seeds of the season! – a good occasion to also publish this post, drafted since late spring.

Aconitum is a large genus with many beautiful species, usually growing in mountainous regions of the Northern Hemisphere, popularly known as wolf’s banes or monkshoods. Many know that they are toxic/medicinal species, but more than that they are highly valued as garden plants.

Like many other species from fam. Ranunculaceae they can prove difficult to germinate from dry stored seeds. Most often it is not possible to moist pack the seeds right away; some collectors are not aware of the requirement or they are unwilling to do it because it is too tedious.

Experienced growers from all over the world will confirm the fact that dry kept seeds of various Aconitum species will generally germinate poorly/germinate in the second year after sowing, or in many cases will never germinate.

My intention is to compile a list for Aconitum species showing their germination pattern when using fresh, moist packed or dry seeds. Knowing which species retain good germination capacity even after their seeds are kept dry for a given amount of time would be very useful.

Generally speaking, we know for sure few facts about Aconitum seeds/germination:
– at the time of seed collecting the embryos are underdeveloped
– the germination can’t occur until the embryos reach a certain size, usually after a period of cold/moist stratification.
– GA3 treatment can promote embryo growth for some species, and thus can be useful in combination with the cold/moist period.

The list below was compiled from my own data and supplied by others on the Scottish Rock Garden Forum, where you can also find a thread open on this subject. Feel free to contribute.

 

And few pictures with various Aconitum species that germinated this spring (2018), in the second year after sowing (dry seeds, GA3 treatment), seedlings, new seeds and the new batch of Aconitum sowings!

Few Aconitum species  will be available late next week!

 

Friday’s Seeds – Callirhoe and the mericarps

, ,

I always strive to make sure the quality of seeds at BotanyCa is top notch. When a few seeds remain available for a given species, it becomes even more an important issue. Such was the case for Callirhoe digitata (Fam. Malvaceae) yesterday.

What we usually call seeds are actually mericarps, parts of a dry fruit called schizocarp; they contain 1 seed each. However, some mericarps can be empty or contain a malformed seed; not too many were left, so a closer look was necessary.

I would like to emphasize that for the purpose of sowing it’s not necessary to extract the seeds from the mericarps.
Reason I did this: to make sure how many good seeds are still available and, to take & show pictures with the actual seeds.

Another similar species, seeds wise, is Iliamna rivularis – Streambank wild hollyhock.
In this case each mericarp contains 2-3(4) seeds, shown below.

Gift cards

,

It is cold and, thanks to Canada Post union, slow going, so I use the occasion to announce the newly posted Gift Cards category – up and running on the shop.

In short: they can be used any time, sent to the purchaser or to the gift recipient or as a pdf file to be downloaded.
The only condition is that the whole value has to be redeemed in one purchase.

Click on the card to read the whole info

Stay tuned for the Friday’s seeds; we will play a ‘seeds game’ to keep us entertained.
The winner’s prize – a 25$ Gift card!

Maybe a consolation prize too; I’m not done yet with the logistics…

 

Friday’s Seeds – the Turtleheads

,

I am pleased to have seeds of two North American turtleheads this year: Chelone glabra and Chelone obliqua.

Both species grow best in moist locations in full sun to part shade and are valuable for their late flowering in August-September; bumblebees can’t have enough of their flowers.

The flowers shape reminds of a turtlehead, reason for their Latin and common name: Chelone = turtle in Greek. Tournefort described Chelone glabra as “Chelone Acadiense, flore albo” (Acadia being the name of Nova Scotia, Canada at the time, around 1700).

I remember reading somewhere that Rafinesque was indignant of the chosen name, arguing that the flowers are not reptiles :) He tried to change it to Chlonanthes but it didn’t work of course. Especially the flower buds do really look like a turtlehead!

But I diverge, here are the seeds. They are very similar, as expected; brown to light tan with a surrounding wing.

Friday’s Seeds – Anemone caroliniana

,

Magic mirror on the wall,
Who is the wooliest one of all?

Anemone caroliniana seeds

Like many other Anemone, this species is easy to grow from seeds and a nice addition for the rock garden/other relatively dry locations.
Those who don’t want/like to grow from seeds can try and visit next year Fuller Natives & Rare Plants in Belleville; many NA ‘native delights’ are awaiting every season for discerning gardeners.

Out in the glowing woods

,

Last weekend it was the perfect time for an outing in the woods; they are basking in the golden glow of the sugar maples these days (Acer saccharum).
Other trees foliage also contribute to a beautiful autumnal display: Fraxinus, Fagus, Carya, Juglans, Amelanchier, Prunus, while on the ground floor Thalictrum dioicum, Smilax, and Aralia nudicaulis foliage reflect the same golden colour.

Acer saccharum – Sugar maple, rock maple

Here and there, attractive ‘candies’ of various species can still be enjoyed:  Viburnum acerifolium,  Maianthemum species, Euonymus obovatus and Smilax herbacea. Others, like those of Amphicarpaea bracteata are not that visible, and you need a sharp eye to find them.

It is also a good time to reflect at the natural associations of these woodland species; we can easily reproduced them in the garden. Amphicarpaea flowering stems were threading over Euonymus obovatus (featured image), Hepatica americana and a nearby Smilax; notice the beautiful clump of Hepatica americana surrounded by the dry foliage of Uvularia grandiflora and the Maianthemum berries shining through Thalictrum dioicum foliage.

Some of these ‘candies’ are already in the shop.
New ones were just added:
Amphicarpaea bracteata
Zizia aurea
Lobelia siphilitica
Lilium michiganense

For the moist packed category in quite small quantities this year: Maianthemum canadense, M. racemosum, M. stellatum and Polygonatum pubescens.

*Native species wise, there will be more seeds to come; the collection goes on until the end of the month. Most species are listed on the Seeds List and will be posted after the seeds are collected and sorted out.

 

WTA!

What the Arisaema! :-)

A couple of years ago I stumbled upon an Arisaema triphyllum population with huge leaves; among them, even a specimen with 3 leaves and two fruits.

Arisaema triphyllum – large form; the seeds are in the shop.

I didn’t carry a measuring tape but the length of the leaflets was much more than 1 ft. (30 cm). I also don’t know the colour of the spathe, anyway I failed to collect the fruits that time.

WTA!

I’ve seen other Arisaema triphyllum with leaves this large but the majority of seeds I collect are from more ‘normal’ (smaller) plants. So, I returned this fall and collected some of the fruits already lying on the woodland floor.

Arisaema triphyllum plants are cross pollinated, so it’s only a matter of luck to obtain an interesting form when growing from seeds.

There is great potential here!

 

A note regarding the germination: all A. triphyllum seeds collections from our region proved to be warm germinators; even older seeds. It will be interesting to see about these ones.

Saturday morning Calochortus

, ,

During a short trip to SE BC this summer I have had the chance to admire my first ever mariposa lily – Calochortus apiculatus, Baker’s mariposa lily – shown here in the featured image. Of course, I’ve seen many pictures of various species, but it’s never the same like experiencing them in the wild.

Next minute, a little voice was screaming in my head – I want to grow a mariposa! Not all Calochortus species are actually named mariposa lilies, but that’s how I call them.
I indulged, and together with a few other Western North American species I brought in, for my little voice and for the shop, 2 Calochortus species.

Not having pictures with the flowers I will introduce them through their seeds.
Calochorthus leichtlinii – the Smokey mariposa, which is found growing at high elevations in Oregon, California and Nevada, would be the one to try in zone 6. It has white to pale blue flowers with yellow/black centers.
With good luck and stellar drainage it may do well. The seeds were collected on Eisenheimer Ridge, Plumas Co. at 2135 m alt.

Calochortus leichtlinii seeds

The very cute Calochortus tolmiei (Tolmie star-tulip, pussy ears) would be best left for those living in a warmer climate, or grown in a pot in the alpine house. The flowers are light purple/lavender and are very hairy – you could grow it as a pet :)
I will test  the germination and who knows, maybe even end up with few plants to grow in a container.

The bundle flower – Desmanthus illinoensis

,

How about a perennial species with mimosa-like foliage for a cold region (zone 5)?
I bet everyone will ask you what’s that species in your garden bed and would want to touch the foliage.

Illinois Bundle flower (or prairie mimosa) is the one.

Desmanthus illinoensis, Illinois bundle flower, prairie mimosa

Unlike the real mimosa plant, the prairie mimosa leaflets will not fold inward when touched, they do it only in the evening and during very hot periods to retain the moisture.
White, globular flowers appear in June/July followed by clusters of pods, which have a beautiful flowery look early on.

Desmanthus illinoensis cluster of pods

It is definitely an interesting plant to mix in a flower bed not to mention that like all Fabaceae it is a nitrogen fixing plant and will naturally enrich the garden soil.

For those interested in the ethnobotanical aspects,  the root bark has been found to contain various substances similar to those used in mix preparation of hallucinogenic drinks (like other species from the mimosa family).

I’ll say let’s keep it for the garden ;)

Single delights – Moneses uniflora

,

“Ever tried. Ever failed. No matter. Try again. Fail again. Fail better.”
Some may argue that this famous Samuel Beckett’s quote is not an inspiration for trying and grow very difficult species, but I differ. With every failure we will, at least, learn something a bit more about them.

This long overdue post is about mycorrhizal species, included in the Orchids & other mycorrhizals shop category and especially about Moneses uniflora – the single delight. It always keeps one to want more ;)

Some people are more adventurous than others when it comes to growing from seeds – this is the reason I collect and offer, when possible, a few almost impossible to germinate/grow species. The cost of seeds is really insignificant; it’s all about the quest and desire to go beyond what’s easy.
In other words, for those loving to grow plants from seeds – it’s also fun!

Moneses uniflora is a little, evergreen species growing in shady, cool places, and not often encountered. Managing to grow it in the garden, it would be nothing short of a miracle but nothing is impossible.
Like all species from the above mentioned category, it requires a specific mycorrhizal fungus at least for germination and maybe even later for growth.

This one single delight was spotted growing on top of decaying, exposed roots covered in moss in the Lizard Mts., BC. In my opinion, this may offer a hint about the way one could go about when trying to germinate it.

Moneses uniflora, single delight (red arrow pointing)

This is my advice for sowing Moneses uniflora (Pyrola and Chimaphila as well):

Collect a piece of decomposed wood together with some moss from the woods; place them in the garden, half buried in the ground to stay moist in a shady location; sprinkle the very fine seeds on top and water well to washed them in the moss. Keep the spot moist at all the time and….fingers crossed.

Few years ago I tried sowing in the same way Pyrola elliptica (same category) with the decomposed wood/moss placed in a pot. I noticed tiny, green sprouts in late spring but then it slipped my attention and got dry at some point, so I cannot draw a real conclusion; must repeat it in the ground in a good shaded place where I water regularly (under a Chinese Epimedium, for example).

Try again :)

As fresh as they get

,

Few species that have been uploaded yesterday on the shop are seeds of opportunity.
Collected by chance during a short trip to the BC mountains, they are maybe one – time offerings. Who knows if I’ll stumble upon glacier lilies in seed (and in flower) some other time?

Seeds of Erythronium grandiflorum, Anemone occidentalis, A. parviflora and even Streptopus amplexifolius are best sown as soon as possible. Otherwise they may germinate in the second spring after sowing.
I can only advise ;)

Erythronium grandiflorum, glacier lily flowering at the snow melt line; the seeds were ready at lower elevation

Anemone occidentalis, early spring flowering (meaning July at high altitude :)

Anemone parviflora

Streptopus amplexifolius

*Since there are quite a few Erythronium seeds, part of them are kept dry and offered at a lower price – Erythronium grandiflorum dry seeds; sown right away they should still germinate in the spring; sown later they will need two seasons for germination.

Not your tiny violet – Viola canadensis

Beautiful and underused in gardens, as it often happens, Canada violet can grow to 1 ft. tall with a round, bushy look habit. Vey floriferous, it looks great in combination with other shade perennials. It prefers a moist location and a few hours of sun will make it remain compact; can be sheared after flowering.

Although listed as growing throughout Canada and most of the U.S, it is rather scarce in the wild and even listed as an endangered species in the Illinois (US).
There are 3 varieties of V. canadensis listed in Flora of North America – those interested can read more:
http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=250100903

Viola canadensis in cultivation

After a good flowering period, the capsules are starting to mature and I’ve collected the first seeds.
Viola spp. capsules display an explosive behavior, reason why collecting the seeds can be a frustrating endeavor, especially from the wild.
In the figures below you can see the way capsules signal the near (1-2 days) release of seeds.

The next stage that follows:

A bit too late ;)

Other Viola species can be monitored for seeds collecting in the same way.
