This is a clump-forming perennial, which is mainly grown for the rose-lavender flowers which appear in summer. These flowers are held on upright spikes above the rosettes of dark green leaves and act as a magnet for bees. It provides great groundcover which is ideal for filling gaps at the front of the border.
How to care for Betonica officinalis Hummelo:
Plant into a well-prepared border with plenty of organic matter (well-rotted compost). Removing the spent flowers will encourage more to form and a light trim after flowering will help keep the plant tidy. Lift and divide large clumps in early spring.
