Obedient Plant is an erect, deciduous perennial best in perennial borders in moist, full-sun locations. It produces grayish-green leaves with white margins and magenta pink flowers. Its flowers remain in the position in which they are placed. It is a showy plant that spreads rapidly if its moisture requirements are met. Plant it in the rear of the perennial border where it has room to spread. If it is shady, the stems will be lax.
