Spring and summer blue-purple to pink tubular flowers broadcast their beauty in clustered semi-whorls. Long stems are clasped by serrated, arrow-shaped leaves. This Penstemon doesn't mind moist soil and is even a bit clay-tolerant. 2' T, clumping; native from the coast to 6,000 feet.

Minimum temperature: -10° F
