Lamium album var. barbatum / Odorikosou オドリコソウ

The Japanese name Odorikosou, for Lamium album var. barbatum, links a group of dancing ladies with rush hats. It inhabits semi-shady portions on roadsides, creating a large population. Pale yellow and white types are also rare. Leaves are opposite, 5-10cm long, in the ovate-triangular to broad-ovate shape, with pointed tips, coarse serrations on margins, and prominent reticulate veins on surfaces. Axils on the upper portions have densely set, white to light red-purple, labiate flowers in whorls. Bloom time: March-June.
