16-20" tall x 15" wide. This new, super cold hardy beardtongue is a real breakthrough, offering gardeners the huge flowers previously seen only with tender Zone 7 or 8 English-style hybrids. Blooming in mid-summer on compact plants, 'Rubycunda's large white-throated, bright red flowers are the favorite of hummingbirds and bumblebees. This is a great beardtongue for more civilized garden conditions. Compost enriched garden loam.
