You don’t have to choose between pretty and hardy with this Penstemon. Its myriad of small tubular flowers put on a dazzling show, and its prairie heritage lets it shrug off tough winters. ‘Prairie Twilight’s’ dainty flowers have white tips and throats, and the wide, lance-shaped leaves sit on sturdy, erect stems. Heavy bloomer in May through mid-July. A spectacular upright element in the sunny perennial border and in containers. Hardy in Zones 4 to 9. Vigorous plants rise to 22 inches and spread to 26 inches.
