Cascade Penstemon is found in moist low elevations along the coastal regions of Alaska, British Columbia, Washington, and Oregon.

This is a medium to tall penstemon; and true to the name (serrulatus), the thin medium green leaves are serrated along the margins.

Cascade Penstemon will develop into a cold hardy sub-shrub in UDSA zones 5-8.

The trumpet shaped flowers tend to be clustered atop the long stems and are blue to lavender sometimes with a yellow beard.

This penstemon thrives near the waters edge and the moist woodland setting so it will do well in a sunny garden situation that is given water.
