perennial herb occurring in the shade of a tree, with stems
measuring 8-20cm in height, and as flowering ends, it bears runners
at the bases to spread out. Leaves are of alternate phyllotaxis,
each with petioles; 2-5cm long blades are cordate, with coarse, wavy
serrations on the margins. Light purple and labiate flowers come
from the leaf axils on the upper parts. Corollas measure
approximately 2.5cm, and the tube portion is slender. Bloom time:
April-May. |
