Does anyone know from first hand experience whether this species (formerly Corydalis claviculata) has ephemeral seed.
It reminds me most closely of Adlumia fungosa (which does not have ephemeral seed).
I hate to moist pack the bit of seed I have for my catalogue, and then have it end up germinating---it has happened, and on more than one occasion. Not enough seed to try both ways as an initial test.
