The stems are topped with stalked clusters of tubular white flowers, which turn dark brown after bloom to form numerous oval seed capsules filled with seeds.

Penstemon is a large genus of flowering plants with approximately 280 different species that are native to only North and Central America. Most penstemons have a durable woody stem, opposite leaves, and tubular shaped flowers. Its most distinctive feature is a prominent hairy staminode visible in the mouth of the corolla, which gives the general appearance of an open mouth with a fuzzy tongue, hence the common name "beardtongue." Penstemons are quite hardy, and are often used in xeriscape landscaping, as many species are native to desert or alpine regions.
