Scrophulariaceae (Figwort Family)


USDA Symbol: MILE2

USDA Native Status: L48 (N), AK (N), CAN (N)

Broadly lance-shaped, light-green leaves line the 1-3 ft. stems of this perennial. Its showy, penstemon-like flowers are rose-pink, marked with maroon blotches and dark lines in the throat. Showy, deep pink to red bilaterally symmetrical flowers bloom in profusion near the top of this leafy, several-stemmed plant.

This is among the most handsome of mountain wildflowers, its deep pink to red flowers probably attracting hummingbirds during their summer stay in the mountains.
