Penstemon grandiflorus
Also called Beardtongue, Penstemon, Beardtongues, Beard Tongue, Garden Beardtongues, Garden Penstemons
Penstemon grandiflorus, known by the common names shell-leaved penstemon, shell-leaf beardtongue, or large-flowered penstemon, is a tall and showy plant in the Penstemon genus from the plains of North America. Due to its large flowers it has found a place in gardens, particularly ones aimed at low water usage like xeriscape gardens.
The exact natural range of Penstemon grandiflorus is somewhat uncertain. It is generally agreed that it grows from Texas to Montana and then east to Minnesota, Wisconsin, and Illinois. Outside this triangle on the Great Plains of North America it is uncertain how far the native range extends. All sources but NatureServe list it has growing in New Mexico. Both POWO and NatureServe list it as an introduced species in Indiana, while the other sources either do not list it or do not make that distinction. Only POWO lists it as an introduced species in Massachusetts, Connecticut, Ohio, and Michigan, though most other sources list it as present in those states.
