I don’t think I need to write too much about the lord of the Corydalis. Wonderful foliage, cold hardy, reliable, handsome, floriferous, fragrant….so we allow him a few ‘minuses’ like going dormant in the summer and not setting too many seeds.
In time it will, and then we’ll complain about being weedy ;) Not happening too fast though.
It will flower starting in the third year when started from seeds; I recommend to be grown with a fair good amount of sun; too much shade will make for leggy specimens.
Germination: best with seeds sown fresh or if kept moist.
Update: shown in the gallery – images of moist stored seeds with split seed coats and germination start in February to mid March.
