"Blackbeard penstemon grows with dark purple, nearly black foliage and stems and bright purple flowers in early summer. It is a perennial plant of medium height with a narrow habit, making it easy to incorporate in both new and existing gardens. Blackbeard stands apart from other dark-leaved penstemons because it remains upright throughout the season, rather than flopping over; it is rock-solid hardy to USDA Zone 3; and best of all its foliage retains its dark color all summer long, rather than fading to green." -- Horticulture Magazine
Penstemon 'Blackbeard' is easy to grow in average, moist to dry, well-drained soil, in full sun. It is tolerant of heat, humidity, drought, while been also very cold hardy. A hummingbird magnet! The basal foliage will remain evergreen through winter.
Penstemon 'Blackbeard' was introduced by Walters Gardens in 2016, as a cross between Penstemon digitalis and Penstemon calycosus, both native to North America.
