Dichroa febrifuga (blue evergreen hydrangea, Chinese quinine) is an evergreen shrub in the Hydrangeaceae family, growing 1-2 m tall in warm-temperate to subtropical forests of southern China, the Himalayas, and Southeast Asia. The opposite, elliptic-lanceolate to oblong, finely serrate leaves are 12-25 cm long, dark green and glabrous above, paler beneath, with a long acuminate tip. Small star-shaped flowers, white to blue or violet-blue depending on soil chemistry, are borne in flat-topped terminal or axillary corymbose cymes; each flower has 4-6 spreading petals and prominent stamens. The fruit is a bright metallic blue, fleshy, globose berry about 5 mm across containing many small seeds. The roots are stout, branching, yellowish-brown, and bitter (POWO; Wikipedia).
