Plant Description

Stachys Hummelo, or betony, is the 2019 Plant of the Year for the Perennial Plant Association. The bright lavender-pink flowers of Hummelo appear in mid to late summer on 1-2' tall, leafless stalks, above spreading mounds that eventually make a solid ground cover. It is very easy in full sun or light shade and average soil.  Deer detest it, but pollinators love it and so will you. It's easy, and long lived, plus lovely.

"Selected and introduced by famed German grower Ernst Pagels in the late 1990’s, this perennial further gained popularity as it was used by renowned designer and plantsman Piet Oudolf in some of his signature works. ‘Hummel’ means ‘bumblebee’ in German. Appropriate, as Ernst observed many pollinators visiting the flowers. The cultivar name also honored Ernst’s close connection to Piet and his nursery and home at Hummelo, The Netherlands.” Greenhouse Management, Nov. 2018.
