This plant is generally and incorrectly known as the Japanese Anemone, A. japonica whose correct botanical name is A. hupehensis var. japonica, a plant that has 20 or more perianth segments. Anemone ×hybrida has 6-11 perianth parts and may reach heights of over 1 m while A. japonica is generally smaller, mostly less than 1 m tall and with sterile pollen. The rarely cultivated A. hupehensis has 5-6 more or less round petals unlike the more numerous and narrower petals of its close relatives. Double-flowered white forms are occasionally offered. The Asian A. vitifolia has leaves that are entire and lobed but never divided into 3 leaflets.
