Plant Common Name

Blue Fumewort

General Description

An equally beautiful but less fussy relative of Corydalis flexuosa, this hardy herbaceous perennial comes from high altitudes in western Sichuan. Growing from a network of short scaly rhizomes, it forms clumps of ferny-leaved, knee-high stems topped by conical clusters of 10 to 30 blue to purple-blue flowers. The two-lipped, long-tailed, coconut-scented flowers appear from late spring through much of summer. Plants may go semi-dormant in summer and push up new leaves in fall. If happy, they spread to form large clumps. Self-sowing may occur if two or more plants are present.

This perennial prefers light to partial shade and moist, well-drained, fertile soil. Protect it from hot sun. It works well in perennial borders, woodland edges, and patio plantings.
