Foxglove Beardtongue (Penstemon digitalis) will thrive despite us.   Growing 3-5’ tall, beardtongue is drought tolerant, tough as nails, and deer resistant. The tubular white flowers in June and July attract and function as a landing platform for long tongued bees, butterflies, sphinx moths and hummingbirds. Do not remove the seed heads later in the season, as they are enjoyed by Northern Cardinals and finches. Caterpillars of several moth species feed on the foliage.
