Nursery contributed plant descriptions

Found in open woods, meadows and prairies of the E. U. S., this wildflower produces pretty white-tinted-purple tubular flowers in clusters on 3-4' stems mid-summer; nice in a wild garden or for the back-of-the-border. S/M
Smooth Penstemon ( Penstemon digitalis) is one of the few Penstemons that thrives in clay! The pure white flowers bloom for a month or longer, and look great with the blue flowers of Ohio and Western Spiderworts. Grows in full sun to light shade, and tolerates seasonally damp conditions. Hardy to Zones 3 - 8.
A clumping evergreen or deciduous perennial. Dense clumps of smooth tongue-like leaves. During Summer slender stems of pale mauve-white foxglove-like flowers are produced.Feed well and remove old flower stalks as necessary to promote flowering.Totally different to the erect Penstemons, except for the flowers.
