Darmera peltata, commonly called umbrella plant, is thick-rhizomed perennial which typically grows 3-5′ tall and is native to mountain stream banks and woodlands from southwestern Oregon to northern California.
Features small pink to white flowers (to 1/2″) in terminal, rounded clusters (corymbs) which appear atop thick hairy stems in early spring before the foliage. Large, rounded, medium green, toothed and lobed leaves (to 18″ across) emerge after bloom to form a foliage mound which remains attractive throughout the growing season as long as consistent moisture is supplied.
This is a substantial plant that needs a large space. Grows well in average garden soil in shaded areas as long as moisture requirements can be met. Also effective in moist woodland areas, native plant gardens, boggy areas or along streams and ponds margins where rhizomes help stabilize the banks.
