Teucrium japonicum / Nigakusa ニガクサ

Teucrium japonicum, a perennial of 30-70cm in height, occurs in semi-shady damp locations, with slender runners underground. 5-10cm long and 2-3.5cm wide, leaves are of opposite phyllotaxis, in an oval-like oblong or broad lanceolate, with sharp tips and margins with uneven serrations. Veins on upper surfaces significantly dent themselves, which is conspicuous. Branch tips emerge 3-10ccm long inflorescences that set small light red flowers. Corollas measure 1-1.2cm in length. Bloom time: July-September.
