A tall perennial for shade that carries long, white, strongly scented bottlebrush spikes from late summer into mid autumn, when most shade plants have finished. Give it moist, humus-rich soil in part shade: the dark-leaved forms scorch in hot sun and dry ground. It is slow to settle in and needs a few years, but then lives long and prefers to be left undisturbed.
