Penstemon pseudospectabilis (Canyon Penstemon)

This perennial grows in canyons and washes across the southwestern U.S., at elevations from 2000 to 6000 feet. Tall spikes of rose-purple flowers attract hummingbirds in the spring and summer. The broad, triangular green leaves are fused at the base of the stem, and have serrated margins. Plant in full sun to part shade and provide excellent drainage. It reseeds readily.
