Large-flowered Beardtongue, Penstemon grandiflorus


Large-flowered beardtongue is one of five species of penstemons native to Minnesota. Of those species, it is one of three found within our growing region alongside white beardtongue (Penstemon albidus) and slender beardtongue (Penstemon gracilis). Like white and slender beardtongue, large-flowered beardtongue prefers relatively dry, well draining sites. It has the most robust stature of our native penstemons, its leaves almost look like large succulent leaves. This appearance leads to it sometimes being called “shell-leaf penstemon.” Other names include: showy beardtongue, pink beardtongue, Canterbury bells, and wild foxglove.

Large-flowered beardtongue is rare to find in the wild and is even threatened in some states. Its stunning large tubular flowers readily attract bumblebees and humming birds. I is a very drought tolerant plant once established, and will thrive on a gravely site where few others can persist.
