'Blackbird' has gorgeous large, dark purple bell-flowers throughout the summer. Narrow, lance-shaped green foliage covers the tall upright stems beneath the racemes of flowers. It is a stunning semi-evergreen bushy, upright, easy to grow perennial.
This Penstemon performs best in either sun or partial shade providing the soil is reasonably fertile, moisture retentive and free-draining. Perfect for growing in coastal locations, pots, containers and your borders. To maintain the vigour of this perennial, deadhead as the flowers fade. Do not be tempted to cut this perennial down before the winter, leave the top growth to protect it. In spring, after the last frosts have passed, cut the plant back hard.
