Stachys monieri 'Hummelo'

Common Name: Alpine Betony

Although Alpine Betony (Stachys monieri 'Hummelo') is related to the familiar lamb's ear (S. byzantina), it doesn't have any of the unruly characteristics of its woolly cousin. Alpine betony has a tidy, non-spreading, mounding form, with medium green, long, narrow, and slightly velvety leaves.

Beautiful, nectar-rich, reddish-purple flowers are borne upright on sturdy stems and are bee and butterfly magnets. (They are also ideal for use as cut flowers!) The blooming period lasts several weeks, from early through midsummer. Alpine betony may be used as a focal point, or in mixed beds or borders. Plant it in drifts for a showstopping effect.

This is one perennial in your garden that won't need much care. Staking isn't necessary and the plants rarely become unkempt, so there is little need to prune. Alpine betony should be divided every three to four years or sooner if the centre turns woody and bare. Very few problems are associated with alpine betony. Aphids and caterpillars may be issues in some years. Alpine betony is an attractive complement to catmint (Nepeta), coneflower (Echinacea), and sea holly (Eryngium).
