General Description

Eurasian in origin, this low herbaceous perennial has dainty leaves and showy pink, purple, red, or white flowers that light up the spring garden. The conical or cylindrical clusters of two-lipped, long-spurred flowers are borne atop one or two short stems that arise from a rounded underground tuber in early spring. Ferny, deeply cleft, compound leaves clothe the lower reaches of the stems. The flowers give rise to elongated capsules filled with small brown seeds that are distributed by ants. Plants go dormant by late spring. They often self-sow.

This perennial is easy to grow if given the right conditions. Partial shade and fertile, humus-rich, well-drained soil are preferred. Cold winters are required, so it cannot be grown in frost-free regions. It dislikes excessive heat and drought. Plant the tubers in fall at a depth 2 to 3 times their width. This plant is ideal for naturalizing in shady areas, or for dotting in perennial borders and rock gardens.
