'Overdam' has variegated foliage that starts out with bright creamy-white margins which then fade to white with a pink flush. The upright clump of foliage will remain under 2' tall. In late spring, strikingly erect, feathery plumes with sand-colored seed heads appear, reaching up to 5' tall. 'Overdam' is an ideal backdrop for low-growing, flowering perennials all through the year.
