Corydalis ochotensis [15 Seeds]
Germination Information: I recommend these seeds only for gardeners who are experienced in handling challenging perennial seeds, because they require some care, patience, and experimentation. They seem to need a period of chilling, which is easiest to provide by surface-sowing fresh seeds in a pot as soon as you receive them (October through December is ideal) and leaving them in a protected place outdoors. The seedlings should appear when conditions are right the following spring.
I have tried starting these seeds in warm conditions (indoors, under lights) and have not had luck that way, so I don’t recommend it.
The seedlings are delicate and easily damaged during transplanting, so you may instead decide to sow in prepared soil right in your garden. Or, better yet, spread the seeds out over several pots (I’d suggest three seeds per 3-inch pot) and carefully transplant each grouping of seedlings to the garden when they are an inch or two tall. Once you get this species to flower, it will happily perpetuate itself by seeding around (at least, it does for me!), and the self-sown seedlings tend to be much more vigorous than transplants.
Note that this information will not appear on the seed packet you receive.

Corydalis ochotensis forms rosettes of ferny green leaves the first year, sending up flowering stems with red-marked yellow flowers the following year, from late summer into fall. They look best mixed among other plants, such as tall asters, that the stems can use for support; they can reach to 5 feet or more that way. Unsupported, they form a somewhat loose, sprawly clump to around 2 feet tall. Full sun to partial shade. This uncommon species usually acts like an annual or biennial in my garden. I’m not sure of its hardiness range, but it is but fine here in Zone 6/7. Be aware that it can self-sow freely.
2022-collected seeds are sold out. I hope to collect again in October 2023. At least 15 seeds. Shipping to US addresses only.
