My own striking hybrid with intense bright blue scented flowers on reddish stems to 75cm, from late spring over a very long season. Repeats in autumn if very happy. Easy, very perennial and bulks up vigorously, in fact this is the most vigorous of all Corydalis in the National Collection! Named as such because it's a true-blue and tends to go on a bit... (flowering that is). Half sun or shade, not too dry.
