Asyneuma japonicum / Shideshajin シデシャジン

Asyneuma japonicum, a perennial herb growing to 0.5-1m in height, inhabits forests in mountainous regions. Alternately arranged, the leaves are small, without petioles, on the upper parts of the plant. In contrast, the lower parts have larger leaves with short petioles, oval-oblong in shape, with pointed tips and uneven serrations along the margins. Flowers set themselves in racemes borne on stem tips and axils on upper parts; peduncles are short, 1-3mm long. Corollas are blue-purple, deeply divided into five lobes from the base, and the lobes are linear, 1-2mm long, open flat, and bend backward; thus, the flowers are seemingly schizopetalous. Bloom time: June-August.
