Blue Fumewort Grown for its true-blue flowers in early summer, Corydalis elata is a small herbaceous perennial with an upright habit. The pretty, divided, yellow-green leaves are a brilliant contrast to the dangling flowers, which appear in May and June. These are cobalt blue, tubular, and scented of gardenia, and in moist soils will go on into mid-summer. Taller, later-flowering, easier and altogether a better plant than the better-known Corydalis flexuosa, blue fumewort has the advantage of not going dormant in summer, although it dislikes summer drought. Good for growing under trees with a light canopy, such as fruit trees, and can also be grown in open ground.
