30cm. Beautiful dark green, shiny foliage, tinted bronze, with pink plumes in late summer. Moist soil or shallow water Clay loving/tolerant.
Astilbes thrive in moist, humus-rich soils in sun or part shade. They tolerate more sun when wetter, and grow in boggy conditions too. The feathery plumes of summer flowers look good for months, flower spikes remaining attractive in winter too, if not cut down.
