Fallopia multiflora
is a perennial climbing herb seen on roadsides, vacant lots, forest
edges, etc., an indigenous-to-China species introduced in Japan
hundreds of years ago. Leaves are oval-shaped with heart-shaped
bases, 3-7.5cm long, and the tips taper off; the petioles have
joints from which leaves tend to leave. Inflorescences are conical,
with both male and female flowers mingling in each of them. Bloom
