Betonica macrantha, formerly Stachys macrantha, known as big betony, is a species of flowering plant in the mint family Lamiaceae. It is native to the Caucasus, northeastern Turkey, and northwestern Iran.[2][1] Growing to 60 cm (24 in) tall by 30 cm (12 in) broad, it is an erect herbaceous perennial with scalloped cordate leaves. Spikes of hooded purplish-pink flowers are borne throughout summer.[3]
The Latin specific epithet macrantha means "large-flowered".[4]
The cultivars 'Robusta', 'Superba', and 'Violacea' have gained the Royal Horticultural Society's Award of Garden Merit.[5]
