Penstemon x 'Midnight'
Beard Tongue - From the large dark-colored flowers and healthy deep green foliage this long-lived cultivar is sure to please. It is an evergreen perennial or sub-shrub to 3 feet tall with purple-tinged stems heavily clothed with 4 inch long lance-shaped dark green leaves. Flowers are large trumpet-shaped and bluish-purple in color. The flowers appear in a succession of flowering peaks from late spring until fall and often appear year-round in coastal gardens. The flowers attract hummingbirds and butterflies into the garden. Plant in full sun along the coast and provide some light shade inland. Tolerates and even thrives in poor soils and alkaline conditions, but requires relatively good drainage. Can survive very dry conditions in cooler coastal gardens, but looks better with occasional irrigation and requires it in hotter locations. Pinch plants after the first bloom to promote a quick re-bloom and cut back hard in winter to encourage a new flush of dense growth in spring.
