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. 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 of 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.
- Therae is some confusion with its nomenclature. Listed as both a synonym and as distinct from E. chysantha. The Royal Hort. Soc. Dictionary of Gardening points out that the 3 species of Edgeworthia are "scarcely distinct". The remaining species is E. gardneri.
