description Penstemon Overview
Penstemon is a large genus of flowering plants found chiefly in North America, with species adapted to habitats ranging from dry mountain slopes to moist meadows. The plants produce tubular, two-lipped flowers in colors that include blue, purple, pink, red, and white. Their flower shape is suited to pollination by bees, hummingbirds, and other animals, depending on the species. Penstemons are grown as ornamental perennials and are especially useful in native, rock, prairie, and drought-tolerant gardens.

What does a penstemon flower look like?
Penstemon flowers are usually tubular and two-lipped, with colors ranging from blue and purple to pink, red, and white. Penstemon digitalis and Penstemon barbatus are two familiar examples.

Are penstemons native to North America?
Penstemon is found chiefly in North America, with species adapted to habitats from dry desert edges to moist mountain meadows. That range explains why one cultivar may tolerate drought while another needs regular moisture.

The tubular flowers of many Penstemon species suit hummingbirds, especially red-flowered forms such as Penstemon barbatus. Bees and other insects also visit species with shorter or wider flower tubes.
