Persicaria sagittata var. sibirica  / Akinounagitsukami アキノウナギツカミ

Persicaria sagittata var. sibirica: A 0.6-1m tall annual occurs on water's edges and stems crawling on the ground. Leaves are oval-like lanceolate to long lanceolate-shaped, with bases sagittate and expand as if embracing the stems. Ochreas are 0.7-1cm-long tubular, with tips that look like they obliquely cut themselves. Flowers, ten or more, with no peduncles, set themselves gathering together on branch tips. Perianths cut themselves into five; the upper parts are light red, and the lower white. Bloom time: June-September.
