An evergreen, carpeting, rhizomatous perennial.
The leaves are heart shaped, mid green and flushed with bronze when young. Pendent sulphur-yellow flowers are borne in spring on panicles that sit just above the foliage and have a drooping, nodding character.
These are superb shade-garden plants, excellent for edging or ground cover. They are frost hardy and will take a couple of years to reach a mature size.
Plants are long-lived and very sturdy.
