Hummelo Betony is a hairy semi-evergreen perennial with wrinkled ovated dark green basal foliage that slowly spreads to make a dense ground cover.   Flower spikes packed with small two-lipped vivid purple flowers last throughout the summer.  Deadheading may encourage a second bloom.  Grows best with afternoon shade in southern climates and dry to medium well-drained soils.  Drought tolerant.
