A native perennial, Betony is found on heaths, woods, and grasslands in England and Wales, but it is rare in Scotland and Ireland. A medicinal herb, Betony was used for a large number of complaints, and was also used to protect against witchcraft. It is also one of those confusing examples where there are two scientific names in modern books. Stachys officinalis is the front runner because it is in the BSBI database.
