Spring and fall

,

Quite a few species that flowered in the spring are opening (or will do it shortly) their fruits to release the seeds.
The fall blooming Crocus species does the same thing. Interesting, isn’t it?

Many of these species are in the category I once called ‘notorious seeds defectors’ :-)
Hepatica, Corydalis & Pseudofumaria spp., Stylophorum spp., Helleborus, Asarum spp. (gingers), Saruma, Viola ssp., Epimediums, the recently added Dirca palustris and so on… (hover over pictures for the names)

It’s Corydalis time!

To say I like Corydalis very much would be an understatement. The delicate, ferny foliage and early, colourful flowering of many species, make them wonderful spring harbingers.
Quite a few tuberous species are easy to grow in the garden in our cold climate (I usually don’t fuss around with pots, except for seedlings): C. solida especially, but also C. caucasica, C. packozy, C. cava, C. bracteata and probably few others.

The same applies for rhizomatous species like C. nobilis, the Pseudofumaria group (formerly C. lutea and C. alba), C. ophiocarpa, C. incisa; also the North American Capnoides sempervirens.

Corydalis incisa and C. ophiocarpa which were grown under lights are already advanced.

I agree it is much easier to buy plants (if available), but for a fast increase of the personal collection, growing from seeds is the better option, not to mention cheaper. They germinate very well if sown fresh or after moist storage. Sowing asap and keeping the pots outdoors (i.e., a warm/cold treatment) is the best option (by asap I don’t mean next day, the seeds sown up to about a month after collecting are OK even if not kept moist).
All you have to do is sow, cover the pots/trays with a mesh and keep them in a partly shaded area; water once in a while. For the winter, place in an area that usually gets covered in snow (or where it is easy to pile snow on top) or a cold garage. By spring they will start to germinate.

For the more adventurous there is also the option on sowing the seeds directly in the garden, reproducing their natural way of multiplying; the seeds are dispersed and buried by ants which feed on the elaiosomes, for which reason, in time they will show up in various places around the garden.

Same applies for Claytonia or any of the other spring flowering species that are best sown fresh: Dicentra, Hepatica, Erythronium, Anemone quinquefolia, Sanguinaria and so on – more about all these soon…

Hot Corydalis

,

It was hot today (felt like 38C!) and I noticed the delicate Rock harlequin (Capnoides sempervirens) flowering. I must say, the colours are just perfect to describe such a fiery day!

It was sown successively from late winter to spring and older seedlings are the first to start flowering now; a few are still growing up. The key to success with this biennial Corydalis (and also some of the perennials) is to plant it in different spots of the garden and, fingers crossed it will reseed and take care of itself afterwards.

If someone noticed, I call it first Corydalis and then I wrote it as Capnoides. Corydalis spp. used to bear the same name. And then, as it happens, few names have changed. I always hesitate: should I write the older name or the ‘new’ one. Many people will always call them Corydalis (and so do I, privately ;)

To resolve the situation, I made a new category for the seeds shop – Corydalis & all, where they can live happily together…
