Hummingbird Trumpet appreciates regular watering the first year or two, particularly during dry winters, to help get it well established.

The tubular, 1.5 inch (3.8 cm) long flowers have 4, notched lobes. The dark green leaves are linear to ovate and may have toothed edges. This native shrub grows in rocky canyons and blooms from summer to late fall. The flowers attract hummingbirds.
