The obedient plant grows to 4' tall and tends to form large clumps. Pink in the late-summer garden is rather rare. Obedient plant's abundant pink flowers that resemble snapdragons on 12" to 18" spikes grace the garden in late summer and fall. The interesting florets are attached to the square stems with wiry little stems (pedicels) that can be pushed into different directions, where they obediently stay put. Good pink perennial for late-summer gardening
