Easy, long-lasting betony blooms
If you have a spot with full sun and well-drained soil, let the eye-catching blooms of ‘Hummelo’ betony (Stachys officinalis) be the star of your summer garden.
Betony is a tidy plant that you can count on to produce plenty of flowers year after year. Its scalloped, glossy dark green leaves look fresh from spring through fall. By midsummer, stems stretch and bottlebrushlike flowers open at the top, holding on for several weeks. ‘Hummelo’ flowers are denser and more purple than the species. And butterflies, bees and hummingbirds flock to the blooms, but deer and rabbits pass on by.
Clumps of betony spread over time, slowly creeping by stolons, creating an attractive stand, like you see at left. Dividing is easy if you want to reduce its size or have more plants.
