This Corydalis has a fern-like appearance and upright, long spikes of small, yellow flowers with a maroon lip, followed by contorted, snake-like seed pods. It will keep an evergreen leaf rosette, which takes a reddish hue. The foliage I would say is its best quality, especially that it doesn’t go dormant in the summer.
It will reseed around so remove the spent flower stems before going to seeds.
Germination: best with seeds sown fresh or if kept moist, sown throughout the summer until fall.
