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 species usually acts like a 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.
Collected in late September and early October 2020. At least 15 seeds.
