Asarum hartwegii (Sierra Wild Winger) is an evergreen rhizomatous perennial boasting heart-shaped, glossy green leaves, 2-4 in. wide (5-10 cm), with conspicuous silver veining. In late spring to early summer, fascinating pitcher-shaped, dark chocolate flowers with tail-like lobes are produced beneath the foliage. Sierra Wild Winger spreads slowly by creeping rhizomes to create a lush aromatic carpet in moist shady areas. A terrific groundcover but excellent drainage is a must.
