Smooth Penstemon, Foxglove Beardtongue

Smooth Penstemon, Foxglove Beardtongue

Penstemon digitalis

Full to part sun, medium to slightly dry moisture level, adapted to a wide range of soils including clay, moderately acid to neutral pH.  3-5 ft. height, blooms late spring to early summer, white flowers, spreads by re-seeding and by short rhizomes in the root system.

Germination Code:  C(30), D, G

Native Region:  Scattered statewide in isolated counties

This is a good, sturdy flower for quick coverage.  Blooms for a month or longer. One of the few Penstemons that do well in clay soil. Even though seeds are quite small, it spreads rapidly by re-seeding.  Striking plant en masse.  Will tolerate dry shade.  Root rot will occur in wet, poorly drained soils. Attracts birds, bees, and butterflies.
