Persicaria muricata / Yanonegusa ヤノネグサ

Persicaria muricata is a perennial that reaches approximately 50cm in height. Its stems have small, downward-pointing prickles and crawl along the ground at the lower parts. Leaves are of alternate phyllotaxis, each 3-8cm in length, oval or broadly lanceolate, the tip pointed, with truncate or heart-shaped bases. Approximately ten flowers come on the branch tops: the peduncles have glandular hair, and the perianths are deeply cleft into five upper parts, red, and the lower ones are white. Bloom time: September-October.
