BotanyCa early fall Seeds List

The Seeds Shop is open for orders!

The early fall Seeds List has been updated as much as possible, with an emphasis on the moist packed seeds. Other species that may be available later have been marked; but the success of fruits/seeds collecting cannot be a sure thing!
Please read the notes with various announcements from the top of the List before ordering; as well the Shipping & Delivery page, otherwise you may not be able to place orders.
Everyone will notice that the Shipping and Handling rates have remained the same. I gave up on the idea of this ever becoming a profitable endeavour, but we must continue to grow plants from seeds!

Available Helleborus species; Hydrastis canadensis – moist packed seeds; Hydrophyllum canadense – may become available later.

I will continue with plant portraits and seeds announcements throughout the fall. Sowing-wise we should concentrate on those species that require sowing right away like:

ALL Moist Packed seeds! – written in green (they cannot be shipped in the winter); please remain aware of dubious on-line offers in this regard.
Paeonia and Helleborus species
Lilium species
the newly offered Streptopus species
Actaea, Aralia, Hydrophyllum, Ilex , Cornus

We remain committed to only collecting a small quantity of seeds from the wild areas, and only from well-established populations. Therefore, we have to be less wasteful and learn how to make due with less. I am sure that sometimes packets with seeds remain forgotten in some drawer… Like in the previous years, species with limited seeds in the stock can only be ordered as 1 pck./person. All the other species, at least for the beginning of the season, can be purchased in max. 2 pck. /person.

Many thanks, as always, to those few friends who generously contribute with seeds, enriching our Shop offerings.

Without further ado – To the seeds and sowing! Thank you all!
It is a continuous learning and rewarding experience like no other.

 

 

Native woodland garden recipe

,

Select a large container (preferably a rectangular one), add a good potting soil mixture, press firmly and add:
 1/2 tbs Trillium grandiflorum seeds (+/- 50 s)
1 tbs Uvularia grandiflora seeds (+30 s)
1/2 tbs Clintonia borealis seeds (or other Trillium species)
1 tbs Caulophyllum thalictroides seeds (+/- 14 s)

Cover with 2+ cm of the same mixture and press well
Water slowly
Simmer for at least 2 years in a shaded location
For best results, dug the container in the ground, cover with a mesh; dry leaves in the fall
You may need to top up with fresh soil in the spring
Continue simmering, check regularly the water status
Ready to consume after 3-4 years (ie. to transplant the seedlings)

Clintonia borealis seeds

Optional, for more flavor sprinkle with:
Streptopus amplexifolius
Actaea spp.
Mitchella repens

Depending on the necessity, you can reduce the recipe in half, replace some of the species, or use individual pots grouped together in a flat or holding container.
*Those adventurous can also sow all these species ‘in situ’ (double up the recipe in that case).

Joke aside, from my own experience it is much easier to handle plant species with similar requirements for germination/growing conditions when grouped together.

Freshly cleaned Caulophyllum thalictroides seeds are back in stock!
Also more Podophyllum peltatum seeds!

Don’t forget to sow the moist packed seeds as soon as possible!
Thank you – Merci- Good luck!

Jeffersonia and Trillium anyone?

,

With many thanks to the owner of the well known by now Aspen Grove Garden (Guelph, ON), who collected and successfully tried a new method for storing hydrophilic seeds, we can continue to indulge in Jeffersonia diphylla seeds.

This lovely (and rather rare in Canada) North American native species doesn’t fit the profile for mass propagation. So, here is the chance to grow it for yourself from moist kept seeds, and give it a home in your garden. True that it takes 3-4 years until reaching flowering age but what a joy to see it starting to grow and flowering every spring afterwards.  I will make it a big event when my first seedlings will flower (next year I hope :)

Not too many seeds available this season; for many spring flowering species the pollination has been affected in our region by the very cold weather. Do not wait too long!

Also, we can relax a bit about Trillium grandiflorum. I managed to collect not too many seeds and luckily now there are more.
Do not relax for too long though because, as I showed every year, most of these seeds will start to germinate (little tuber/root) somewhere in September and after that shipping is not possible anymore.

Trillium grandiflorum fresh seeds 2019; most of these seeds will start to germinate (tuber/root only) somewhere in September/early October! like shown in the picture below

Trillium grandiflorum germinated seeds after a first warm cycle; the first leaves will grow after a cold cycle (ie. winter); part of the seeds will only germinate in the second year after sowing

There is plenty to read on this website about growing Jeffersonia and Trillium from seeds, I’ll leave you to the readings :)

We’ll talk later about how to easily keep hydrophilic seeds in good condition for a few months without bothering with Ziploc bags and moist vermiculite.

PS. Caulophyllum thalictroides mix seeds also in stock!

Out in the woods – Trillium grandiflorum

,

The time has come to admire again the Large white-flowered Trillium in all its forms and also few other woodland companions.

Although Trillium grandiflorum takes center stage at this time, it doesn’t grow by itself and I will show just a few species that were growing beside it in one particular area: Caulophyllum, Podophyllum peltatum (May apple), Maianthemum racemosum (False Solomon’s Seal), Uvularia grandiflora, Asarum canadense, Viola rostrata, Viola sororia. Others not shown here which associate in the wild/woodland gardens: Actaea species, Polygonatum pubescens, Thalictrum dioicum, Hepatica americana/acutiloba, Sanguinaria, Arisaema triphyllum, Viola pubescens and of course Trillium erectum.
Seeds of all are usually offered in the Seeds Shop by fall.

No-DOD’s

,

(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)
