Penstemon canescensAlso known as:
eastern gray beardtongue,
Penstemon canescens flowers are 1" long, trumpet-shaped,and reminiscent of those of the snapdragon. They are usually pale shades of pink to lavender, but occasionally deep shades of purple and violet. They bloom atop rigid hairy stems, 2' tall or more. Opposing pairs of lance-shaped leaves may grow up to 2" long.
Easily grown in average or even poor soil, in full sun, this clump forming species is an excellent choice for a medium height plant to add a focal point in a rock garden or a dry border. Spent flowers may be cut to prolong bloom time. Plants may be cut back hard after blooming to improve their appearance. Susceptible to root-rot if kept wet. May bloom from May through July. Zones 5-7
Best propagated by division before or after bloom time. May also be propagated from seed.
From the Greek word penta, meaning five, penstemon refers to the five stamens typical to this large genus. The common name beardtongue is a reference to its one, furry, sterile stamen (the other four are fertile).
