Habit:
A hardy herbaceous
perennial that develops upright flower stalks emerging from a basal rosette of
leaves. Similar in habit to Smooth Penstemon Penstemon
digitalis but with tubular rose pink to lavender flowers. Flowering last for three weeks in late spring.
Calico penstemon is more adapted to shade
than other penstemons but is less drought tolerant. It prefers moist rich loamy
soils in light to moderate shade but is tolerant of varied soil, moisture and light conditions. Under full sun conditions it
requires moister soils but can still tolerate periods of drought.
This
is a desirable early season perennial for shady conditions. Plants are easy to
grow from seed and it readily naturalizes and spreads by seed. Plants
are pest resistant and unpalatable to deer and other herbivores.
Long tongued bees, butterflies, sphinx moths and hummingbirds
are attracted to the flowers and caterpillars of several moth species feed on
the foliage.
Calico Beardtongue can be found in open rocky woodlands, wet mesic woods, oak savannas, moist meadows, woodland edges and clearings, stream banks, limestone
outcrops, pastures and roadsides.
Penstemon
calycosus occurs in the eastern United
States from Maine to Georgia and west to Minnesota and Missouri in a variety of
habitats.
Rose pink to lavender tubular flowers attract numerous
pollinators.
