Noted for its incredibly dark blue flowers, Corydalis curviflora subsp. rosthornii ‘Blue Heron’ (Fumewort) is a showy, erect perennial forming an attractive mound of lacy, highly divided, blue-green leaves. From late spring to mid-summer, large, very fragrant, sapphire blue flowers are produced atop stunning red stems above the foliage, creating a remarkable contrast.
