Anemone hupehensis var. japonica, a type of buttercup in the genus Anemone. Anemone hupehensis is commonly called the "Japanese anemone", but it is actually native to China. The flower's petals may be white, purple, or pink in color, with yellow stamens and green foliage. It produces three-parted leaves in clumps about 2 feet (0.61 m) wide. The plant may also be invasive or weedy in some areas, due to its tendency to spread quickly if left alone and the fact that it can survive in all but the hottest and driest conditions.Photo credit: Noodle snacks
