(syn: Actaea biternata) Finally, a superb cimicifuga that grows and flowers in our heat! In our cimicifuga-deprived climate, we could only indulge our passion for these plants by falling asleep with English garden design books. Now with Cimicifuga japonica, we can have our bugbane and grow them too. Each 1' wide clump of Cimicifuga japonica has glossy basal foliage, like a giant thalictrum, topped in mid-September with clouds of 2.5', narrow, bottlebrush-like white wands. While moist soils are preferred, all but the driest soils have proven satisfactory.
