Dependable germinators

and the Rock harlequin

Usually mid-month I check on the moist stored seeds. No surprise this time; Trillium grandiflorum had a wave of germination in October, as per usual. No reason to panic; knowing it will happen I collect more seeds than would sell. The remaining of the seeds will germinate only after a cold period. In the case of T. erectum only very few seeds will germinate in the fall (without a cold period).

What I would like is to be able to tell which ones will germinate right away; unfortunately, these little skotomorphogenetics like to keep a bit of a mystery about themselves…


Trillium grandiflorum – many seeds will germinate (small tuber and root) at room temperature by November when stored moist after collecting.

What else? Asarum canadense is also one dependable germinator, and so is Allium tricoccum.


Asarum canadense (wild ginger) – the seeds will grow a small root after a warm period and the leaves will emerge in the spring after a cold period/winter.

Then there is the ‘grand mischief’ – Capnoides sempervirens (formerly a Corydalis).  It will germinate when it likes (from summer to late fall) and where it likes (that is, almost everywhere :) Later the seedlings are easily moved to a desired location or potted up).

I noticed the seedling in the image below since it was very tiny and I enjoyed seeing it grow. To be honest, who else besides the Rock harlequin, would like to call home the tiny space between the garden rock and a cement slab?

Centaurea species seeds don’t need moist keeping but are also dependable germinators, and one result: C. triumfettii ssp. stricta was looking so magnificent yesterday that I couldn’t abstain taking one more picture. Snow will arrive soon and every little flower must be enjoyed!
