'Rubycunda’ is a new, super cold-hardy beardtongue that is a real breakthrough, offering gardeners the huge flowers previously seen only with tender Zone 7-8 English-style hybrids. Penstemon barbatus blooms in mid-summer on compact plants. Its large, white-throated, bright red flowers are the favorite of hummingbirds and bumblebees. ‘Rubycunda’ is a great beardtongue for gardens throughout Zones 4-9. This lovely plant will reach 16 to 20 inches tall and 15 inches wide. Each plant in a premium 5-inch pot sells for $8.99.
