Seeds collecting in February?

,

Yes, it is possible especially if you don’t pay good attention in late fall.

Somehow I didn’t notice the first fruit produced by Calycanthus until last Saturday! It flowered beautifully last spring and then a few green fruits were aborted during late summer. I thought that was it and didn’t pay attention afterwards.
A nice surprise; I received the young plant three years ago from a friend and it was very satisfying for both of us to see it fruitful :)

Calycanthus floridus (Carolina allspice) is an excellent native shrub which can be grown in many situations from sun to shade; fast growing with beautiful shiny foliage, it is rarely affected by any pests. Did I forget to mention the sweetly fragrant, burgundy flowers?
The fruit is an interesting large, brown capsule, which can be mistaken with a fallen leaf/small branch, and holds few large seeds. They are very easy to germinate (read about nicking) and show up with convoluted cotyledon leaves (a rare case).


Speaking NA natives, I put together a short list of other species which flower around the same time in mid April-May, and are suitable for cold climates. They all grow in the same bed with the Calycanthus. If only I would have more space….
T. cuneatum, T. luteum, Uvularia grandiflora, Mitella diphylla, Asarum canadense, Hepatica acutiloba, Trautvetteria caroliniensis

Notes on germination: Erythronium I

Notes on Erythronium germination I (February 9, 2019)

Just a note for those who purchased Erythronium americanum seeds last year (that was a nice crop) – the seeds kept in moist storage at cold (fridge) are germinating! Luckily that I had to look for other moist packed seeds for an order.
Depending where you are, temperature wise, this may be happening in your pot right now! Exciting :)

Erythronium americanum germinating seeds Feb.9 2019

E. grandiflorum seeds are looking OK but no signs of germination yet, after all they were collected much later than E. americanum. I’ll keep you posted.
More sowing to do….

Belated Fridays Seeds: Paeonia brownii

, ,

I forgot about the Fridays Seeds :o
In my defense, I was trying to finish the first batch of winter sowings, before other/new seeds arrive. Being end of the month I also had to check all the remaining moist packed seeds, kept at cold or warm.

A leisurely Saturday is a good occasion to show the seeds of Paeonia brownii.
I didn’t show them before because all seeds that arrived were presold and none of them made it to the online shop inventory. With more requests left unsatisfied I didn’t want to aggravate the situation.

Paeonia brownii is one of the only two North American peony species and it has different seeds than the ones we are more used seeing. I would call it the Cinderella of the peonies (seeds wise) because they are nothing but attractive, especially when dry: brownish and large with an irregular shape.

In the rush of the moment I even missed to take pictures of the dry seeds; the ones shown here are already in moist packing since late October (kept at warm).

Paeonia brownii seeds: kept in moist storage since late October. Moist seeds should not be left to dry out at any moment, hence only a quick picture with the seeds on moist towel ;)

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.

Callirhoe digitata (Fringed poppy mallow, standing wine cup) – mericarps and 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.

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 ;)
