About
Corydalis omeiana is a perennial that thrives in partially shaded woodland areas. It features light green foliage composed of two to three ovate, lobed leaflets, creating a dense mat reminiscent of ferns. The plant produces tubular blue-purple flowers arranged in compact racemes, blooming from late spring until late summer, after which it may enter a dormant phase.
