Comfrey

Symphytum officinale

Comfrey is the classic permaculture multi-purpose herb — deep taproot mines subsoil minerals, bell-shaped purple-pink flowers feed bumblebees through summer, and the fast-regrowing leaves chop-and-drop into a potent mulch or compost activator. The 'Bocking 14' cultivar is sterile and won't self-seed.
