Tag Archive for: Caulophyllum

The unusual warm weather experienced in SW Ontario for a while has determined many spring beauties to explode into fast growth and flowering. Then, the torrential rains arrived, and now we are heading backwards to the winter…(snow showers outside at the moment).

This is, most years, the early spring time in Ontario!

The earliest spring beauties are in flower: Lindera benzoin, Lonicera canadensis, Claytonia virginica, Caulophyllum, Hepatica americana and H. acutiloba.  Sanguinaria canadensis has almost finished flowering (depending on the region) and yesterday I noticed the first trout lilies blooming, plus Trillium erectum and T. grandiflorum with buds just about to open! The wild ginger is well on its way of carpeting the woodland floor/garden.

In the garden, few Primulas and Helleborus have been flowering for a couple of weeks now alongside Corydalis.  Other spring beauties are appearing almost on a daily basis. *Our native Primula mistassinica is in flower as well but I didn’t take a picture yet.

Young shoots of Caulophyllum thalictroides/giganteum

*Young seedlings have also appeared and some new sowings are starting to germinate.
Especially for those who have sown Caulophyllum in the ground two years ago (and the few lucky ones who received one year-old stratified seeds) –  be careful because the young shoots are dark colored (almost black) for a while and they can be easily stepped upon. Same goes for other directly sown native species in the ground, even if green colored/or sown in pots: Asarum  and Stylophorum diphyllum, Hepatica, should be germinating around this time, or soon.

 

Being seed adventurous doesn’t mean only going into the woods and climbing mountains in search of plant seeds. It also means, trying new species from seeds and looking to improve or find new methods of sowing/germination. Wanting to avoid having to handle too many small pots, last week I sowed in the same container a few species with similar requirements (germination/growing conditions) in rectangular wood-fiber container, which was ‘planted’ in the ground in a shaded location (but it could also be kept like other pots outdoors and planted in an appropriate place only in the spring).

Species with hydrophilic seeds sown together

Container with Trillium sp., Uvularia grandiflora, Clintonia borealis…Anti-squirrel mesh and owl for good luck :)

I planted a second container with Caulophyllum thalictroides in combination with Medeola virginiana. But, one could also use individual biodegradable pots if the mixing of species is not desired.

By the time the plants will be big enough to be moved/spaced out (if necessary), the container will be decomposed. This way the seeds and seedlings will have the advantage of a good water retentive sowing mix; of course, not all of them will survive, but this is how it also goes in a natural setting. This may be turn out to be a very good method for growing those species that need two years (or more) to complete germination and have similar growing requirements, like Trillium, Uvularia, Maianthemum racemosum, Polygonatum…and also for those species that have very tiny seedlings and don’t require transplanting until the second or third year.

And to give one more idea, the featured image shows Caulophyllum thalictroides seeds sowed directed on the woodland garden floor – but this will be a whole story for later…
