Plant Common Name

General Description

Native from southern Scandinavia to Italy and Greece, this low herbaceous perennial has dainty leaves and modestly attractive pink or purple flowers in spring. The conical or cylindrical clusters of small, two-lipped, long-spurred flowers are borne atop one or two short stems that arise from a rounded underground tuber in early spring. Leafy flower bracts often partially hide the blooms. Ferny, deeply or shallowly lobed 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, and may hybridize with Corydalis solida.

This perennial is easy to grow if given the right conditions. Partial shade and fertile, humus-rich, well-drained soil are preferred. It differs from many other shade-loving corydalis in favoring neutral to alkaline soil and tolerating some drought. Cold winters are required, so it cannot be grown in frost-free regions. Plant the tubers in fall at a depth 2 to 3 times their width. This plant is good for naturalizing in shady areas.
