The large-flowered penstemon (Penstemon grandiflorus), a wildflower in the snapdragon family, is found in prairies in the Great Plains and the Upper Midwest—and in Carleton’s Cowling Arboretum and McKnight Prairie. “We use this plant extensively in the Arboretum prairie restorations,” says Nancy Braker ’81, director of the Arb. “It provides a great nectar source for hummingbirds and native bees and is beautiful in early summer, especially around Reunion weekend!”
