Also called balm-leaved archangel,, this clump forming herbaceous perennial is native to central and eastern Europe. The heart-shaped leaves are up to six inches long, softly hairy and have serrated margins. Whorls of coppery pink to purple flowers are carried on spikes 1.5” long in spring and summer. Each flower is hooded and two lipped, with delicate markings in the throat. The flowers are often somewhat obscured by the leaves but the plant is worth growing for its foliage. It is an excellent ground cover for shady borders or with shrubs and is not invasive.
