Ever-reliable and hardy, penstemons are long flowering, easy-care perennials that are invaluable in the garden. With rich burgundy tubular flowers that hang elegantly from its stems, ‘Blackbird’ makes a striking combination with grey foliaged plants in a border garden.
Tolerant of dry periods once established, penstemons are easy-care perennials for most conditions, preferring full sun, free-draining position. Water regularly during dry periods for improved flowering and performance. Prune back to a low mound after flowering to maintain a compact habit. Water regularly to promote vigorous flowering.
