Betony 'Hummelo' Characteristics
'Hummelo' are easy to grow, clump-forming perennials that can create a thick groundcover if allowed to spread. The soils should be consistently moist, but some drought is tolerable in established plants. Runners spread from the base of the plant and occasionally root where they touch the ground. Cutting spent flower stalks may allow 'Hummelo' a second bloom in one season.
There are few serious disease or insect issues that threaten 'Hummelo'. Snails and slugs may munch on the leaves.
