Penstemon digitalis is naturally found in eastern and south-eastern North America growing in woodlands in well-drained moderately fertile moist soils. It prefers a open sunny position and is drought tender but heavy frost resistant.

This vigorous perennial is grown for its flowers and is planted in large rockeries or in raised garden beds as a low filler or specimen plant. It may also be grown in pots and tubs establishing in 1 to 2 years from cuttings but may be short lived. It is suitable for mountain or coastal regions and requires ample water during summer. In very cold climates the stems may be deciduous. ID 1585
