Corydalis 2023
We shouldn’t let the spring go by without admiring and talking about Corydalis species.
Last year’s drought coupled with an April brief surge of temperature resulted in a not so great display of Corydalis solida. Few other species, like Corydalis malkensis (in the featured image with Helleborus caucasicus) and Corydalis paczozkii weren’t bothered as much. Corydalis nobilis is just starting to flower now, as usual.
Every year has its lows and highs in term of flowers display. Even so, the colorful masses of spring Corydalis can hardly be equaled by other ephemeral species. There are a lot of pictures already uploaded on this website (scroll to the bottom of this writing for related posts) so just a few for this spring.
Those new to this website and to the ephemeral Corydalis species can read about Growing Corydalis solida & allies from seeds by clicking on the link.
There is always looking forward to growing more Corydalis species, and early spring is a good time to also boast about our seedlings, thanks to attentive friends :) These were all grown from fresh seeds following the same sowing recipe as described above.
The following article about Corydalis ambigua, also remarks the similarity in the germination pattern between various bulbous Corydalis species of temperate climate regions (link) – Ecophysiology of seeds dormancy and germination in the mesic woodland herbaceous perennial Corydalis ambigua in Japan: Tetsuya Kondo, Nori Okubo, Taku Miura, Carol Baskin.
Even more, Corydalis nobilis, albeit not bulbous, also germinates in the same way. Remnant seeds in the fridge have their seedcoats split and would germinate if/when moved outside of the cold storage.
Regarding Corydalis offerings for this spring
I will try my best to collect some seeds, but because the flowering hasn’t been too great, at least for C. solida, the seeds set will also be reduced. The same can be said about our native Hepatica species; the persistent drought of past years was reflected in poor flowering.
We can only know what and how many such seeds will be available towards the end of May.
