Genus: Penstemon
Common Names: beardtongue
Penstemons (also called beardtongues) are the largest genus of flowering plants native to North America and come in various sizes, shapes, and colors. Throughout the 1900s penstemon species from Mexico and the Southwest U.S. were imported to Europe and bred and hybridized specifically for long, showy blooms and adaptability into traditional Western gardens. Many of these hybrids (and their descendants) are still around today and have been a staple of pollinator gardens everywhere. .
