Edgeworthia chrysantha

Edgeworthia chrysantha, also known as Edgeworthia papyrifera, Mitsumata, Paperbush, or Oriental PaperBush, belongs to the Thymelaeaceae family of plants. It is native to China and holds historical and cultural significance in various regions. The plant was named in honor of Michael Pakenham Edgeworth, an esteemed Irish botanist of the 19th century. The specific epithet “chrysantha” stems from the Greek words “chrysos” meaning “golden” and “anthos” meaning “flowers,” alluding to the plant’s beautiful golden blooms.

The Japanese name “Mitsumata” refers to the traditional paper made from the plant’s bark. Edgeworthia chrysantha is a deciduous shrub that offers unique ornamental features. It exhibits a fascinating flowering pattern, as it blooms in early spring, even before its leaves emerge. The flowers of Edgeworthia chrysantha form rounded clusters composed of numerous small, yellow flowers that emerge from hairy buds. This gives the plant an intriguing textural quality. The foliage of Edgeworthia chrysantha is dark green, with lanceolate-shaped leaves arranged alternately along the branches.
