Herb
Creeping Pennyroyal
A tier
Creeping pennyroyal describes the prostrate growth habit of Mentha pulegium selections used as aromatic groundcovers between stones—intense mint smell when stepped on, same species chemistry as upright forms. Landscaping use outranks culinary use. If leaves enter a historical recipe, dose at trace levels only. Keep away from pets that chew leaves aggressively; potency is high.
