Peristrophe japonica / Hagurosou ハグロソウ

Peristrophe japonica is a perennial herb bearing unusual flowers in the shady, moist places at the skirts of mountainous regions. The stems sparsely branch to reach 20-50cm in height. Dark green leaves are of opposite phyllotaxis, with 2-10mm pedicles, blades with ovate-oblong or lanceolate, 2-10cm and 1-2.5cm wide, and entire margins. Branch tips or upper parts' axils emerge peduncles and set on the tips two foliate, enveloped with ovate-oblong bracts, red-purple flowers. The corollas are bilabiate, the lower ones are broader, and the stamens are two. The lavender labium is conspicuous, significantly contrasting its leaves and the other green leaves. The lips reportedly attract pollinators and serve as a landing platform. The fruit (capsule) measures 9-12mm long. Bloom time: September-October.
