(=‘Conalba’) Barrenwort are superb shade-garden plants, excellent for edging or massing. This selection forms a bushy mound of bright-green leaves, bearing sprays of delicate white flowers in mid to late spring. Although it takes a few years to reach a mature size, plants are long-lived and very sturdy. Old leaves should be pruned to the ground in late winter to show the flowers to best effect. Drought tolerant once established. A seedling discovered by Dr. Richard Lighty in his Pennsylvania garden. USPP#20344: unlicensed propagation prohibited.
