Hummelo Betony | Stachys officinalis
Plants form a bushy mound of crinkly green leaves, with showy upright spikes of purple-pink flowers in summer. Beautiful in the border, or beside a stream. Good for cutting. Also worth trying in tubs or mixed containers. Plants may be easily divided in early spring. Seems to require a rich, moist soil. Remove faded flowers regularly to encourage more buds to form. Clip back hard immediately after flowering, to tidy plants up for the rest of the season.
