Clumps of stiff erect stems, which are more rounded than other species, of toothed and boldly veined mid to dark green leaves and in late summer, heads of curiously-shaped deep purplish-pink flowers, each appearing to have a gaping mouth reminiscent of its common name, with small yellow beards.

Deep, fertile, moist or even very wet soil. Will thrive in heavy clay. Partial shade or sun.

By division in spring. Also from seed or soft tip cuttings.

Can be grown in a bog garden or a border that does not get too dry. Useful for late summer colour.
