A wonderful perennial for fall colour, Chelone Iyonii (Pink Turtlehead) is an upright, clump-forming perennial with abundant terminal spikes of fascinating, two-lipped, pink to rose-purple flowers from late summer into fall. The hooded flowers are shaped like turtle heads just emerging from the shell, hence the common name of 'Turtlehead'. They rise above a lustrous foliage of broadly, lance-shaped, dark green leaves that are arranged in pairs along the stiff, square stems and remains attractive during the growing season.
