  • Broadleaf deciduous shrub, to 5 ft (1.5 m) or more.  Leaves single, alternate, lanceolate to narrow ovate, 8-13 cm long and 2-5 cm wide, entire, dull green, gray-green below with silky hairs when young.  Blooms in winter when leafless.  Flowers in clusters of 35 or more at branch tips, slightly fragrant, each flower is about 1.5 cm long, a 4-lobed silky calyx, white on the outside with a yellow center, lacks petals.  Fruit of Edgeworthia is a dry drupe, apparently not often seen on this species?
  • Full sun or part shade. Little pruning required.
  • Hardy to USDA Zone 7      Native to China, in forests and especially by streams.  Used as a source of high grade paper in Japan.
  • There is some confusion with its nomenclature.  Listed as both a synonym and as distinct from E. papyrifera.  The Royal Hort. Soc. Dictionary of Gardening points out that the 3 species of Edgeworthia are "scarcely distinct".  The remaining species is E. gardneri
