Penstemon is a large genus of North American (and East Asian) plants traditionally placed in the Scrophulariaceae family. Due to new genetic research it has now been placed in the vastly expanded family Plantaginaceae.

with opposing leaves, two-lipped flowers and seed capsules. They are also called beardtongues, after the general appearance of an open mouth with a fuzzy tongue protruding.

Nowadays the one Asiatic species is considered a separate genus. This leaves Penstemon a mostly Nearctic genus, with a few Neotropical specimens. Penstemons are ideal for xeriscape landscaping, as many thrive in desert regions.
