Astilbe rivularis var. myriantha

A striking, very tall species with bold compound foliage making a good mound of large leaflets, giving rise in autumn to 2m high inflorescences of creamy-white flowers in pyramidal, airy, branched heads. A real understated beauty of some size, looking great even in seed when the pods turn deep-red and the foliage starts to turn to deep red tones. For soil that doesn't get too dry in sun or semi-shade. This form originated in Sichuan.
