Welcome to the site dedicated to all things Penstemon - an exclusive family of flowering plants found only in North America. Their 280 species include some of our most beautiful wildflowers. Penstemons can be found in a wide variety of habitats ranging from the mountains of Guatemala to the tundra of Canada and Alaska. They have also been adapted as wonderful plants for our gardens. In addition to the natural species there are over 800 cultivars and hybrids that have been developed by plant breeders over the last 300+ years. Penstemons range in size from an inch or so to over seven feet in height and the color range of their flowers covers the spectrum.
