Penstemon grandiflorus has large lavender or pink flowers that attract hummingbirds. The blue-green leaves are shaped like shells.

Penstemon grandiflorus is one of the hardiest and showiest penstemons. It is relatively easy to grow, tolerating more moisture than most species. Of course, it still needs well-drained soil, and it may require staking in wet weather because the flowering stems are heavy.

Also known as Penstemon grandiflora and Large Flowered Beardtongue. Native to the Great Plains. Hardy perennial in zones 4-9.
