Say you do, say you do, Cheju-Do! Basal clumps of expanding glossy lobed leaves erupting with multiple 30” spikes of white buds flare to delicate, brushy flowers in late summer/early fall. Interesting and rarely offered, this perennial enjoys bright shade in moist, organic soil. Very at home at woodland’s edge. If happy, clumps will expand into small colonies.  USDA Zone 5-9  3″ pot
