Siskiyou penstemon is native to southern Oregon and northern California, including its namesake Siskiyou Mountains. It has distinctive, large, glossy green basal leaves, and oppositely arranged, smaller, clasping leaves along the stem. Siskiyou penstemon grows .5′-3′ tall and has cheerful, showy tubular flower clusters that range from light blue, violet, to purple. The glandular flowers bloom June-August. Unlike many penstemons that are sun-loving, Siskiyou penstemon prefers part-shade in coniferous forests at mid to high elevation. It can be found in small openings in the forest canopy, in open meadows, and in disturbed areas, such as post-fire habitat. Easy to grow in the garden environment in part-shade with well-drained soil. Will benefit from occasional summer irrigation at low elevations. Attractive to many species of native bees, moths and hummingbirds.
