Botanical Name

Plant Common Name

General Description

Native to rocky and sandy slopes and clearings over much of Canada and the northern United States, this biennial bears clusters of small bicolored flowers from early summer to fall above rosettes of lacy blue-green leaves. Deployed on erect, calf- to waist-high stems, the spurred, purplish-pink flowers have gaping yellow mouths. The blooms give rise to small pod-like capsules containing round shiny black seeds that are distributed by ants. Plants will self-sow where happy. Plants die at the end of their blooming season.

An ideal subject for the wild garden or informal border, this charming plant prefers sun or light shade and well-drained soil. Plant seed in fall for spring germination.
