Penstemon Blackbeard
Penstemon Blackbeard


Blackbeard was a famous English pirate known for his black facial hair. The name of this hardy perennial is a play on words from the common name for Penstemon, Beardtongue. This plant features dark purple flower stems holding its lilac purple flowers with their white flaring tubes high above the low mound of deep eggplant purple leaves. Attractive dark burgundy seed pods follow the flowersfor extended seasonal interest. ‘Blackbeard’ stays strictly upright all season long.
Like all of our Penstemons, this one takes the heat and humidity in stride but is also very cold hardy. It continues to provide terrific color in the landscape all season long.

Growing and Maintenance Tips

Penstemon 'Blackbeard' is easy to grow in full sun in rich, well drained soil. Avoid wet or poorly drained soils and soils with low fertility. After flowering you can cut the spent blooms back and enjoy the lovely foliage colour. We do not cut this plant back because we find the stems and seed heads very attractive. A mulch will help to retain soil moisture and keep the leaves clean.
