About

Achyranthes japonica, commonly known as Oriental chaff flower or Japanese chaff flower, is a perennial member of the genus Achyranthes in the family Amaranthaceae. It can be discovered on the roadside and its main distribution is in Korea and Japan.

Where it grows

A. japonica is a perennial plant growing to 50–150 cm (20–59 in) in height with thickened roots. Stems are quadrangular, branched, and glabrous or slightly pubescent. Stem nodes are dilated. The petiolate leaves are opposite, elliptic or oblong, and slightly pubescent, 10–20 cm (3.9–7.9 in) long and 4–10 cm (1.6–3.9 in) wide. Leaf veins show an arced pattern similar to that of dogwoods. Tiny green flowers bloom from August to September, with "bottle-brush" inflorescence spikes in axils and at terminals of the stem. Each flower has five fused stamens and a single pistil.
