In wetlands, Stachys aspera, a perennial herb, height
40-70cm, propagates by extending long white rhizomes with stems with
ridges and downward prickles. The phyllotaxis is alternate; leaves
are 4-8cm long and lanceolate-shaped, with wrinkles on the upper
surfaces and spines on the backside mid-ribs, which feel sandy. Stem
tips bear short spikes and set a few rows of light red labiate
flowers; corollas are about 1.5cm long, and the lower lips cleft
themselves in three, with red spots. Bloom time: July-August. |
