Brilliant violet of the most unbelievable purity. I rate Corydalis in my top 10 for garden value. Bunches of spurred tubular flowers above finely filigreed leaf mounds of maidenhair like lace. Very long blooming with flushes of flowers late winter, spring, summer and autumn. Low care – an annual haircut is all they ask. Shade or ½ shade. Frost hardy. Respond lushly to mulch.
