Smooth White Beardtongue (Penstemon digitalis) produces white blossoms in late spring to early summer. Native to eastern North America, Penstemon digitalis is a nectar source for butterflies, and a pollinator magnet in the late spring and early summer. It has special value to bumble bees and native bees, particularly small carpenter, wool carder, digger, sweat, and leafcutter bees. Small and medium sized bees are the most frequent visitors, and certain mason bees and pollen-collecting wasps are specialists.

Penstemon digitalis attracts syrphid flies, a beneficial insect which feeds on aphids. It may also be visited by hummingbirds.

This Foxglove Beardtongue is the most common of the white flowering beardtongue species in eastern North America. It grows in meadows, prairie, and open woods from South Dakota through southern Quebec to Maine and southward into the South. It is sold by a good number of native plant nurseries.

"Penstemon digitalis (penstemon) is a plant in the plantain family, Plantaginaceae. The flowers are white and are borne in summer. It is native to Eastern and Southeastern United States. Its common name is Beardtongue.

Penstemon digitalis is a herbaceous plant with opposite, simple leaves, on slender, purple stems. It is sometimes called beardtongue, as the stamen has small tufts of "hair". It produces tubular white flowers on 2 to 3 foot stems over attractive dark green foliage. The flowers are produced in June, adding color to the prairie garden. The plant grows in any moist soil in full sun."
