Anemone hupehensis

Anemone hupehensis, Anemone hupehensis var. japonica, and Anemone × hybrida (commonly known as the Chinese anemone or Japanese anemone, thimbleweed, or windflower) are species of flowering herbaceous perennials in the Ranunculaceae family.

Anemone × hybrida Paxton is a hybrid of Anemone hupehensis var. japonica and Anemone vitifolia. It should not be confused with Anemone hybrida Miq. ex Pritz., a synonym of Aanemone halleri All.

These plants thrive best in shady areas and under protection of larger plants, and in all but the hottest and the driest conditions in the United States. They are especially sensitive to drought or overwatering. They can be invasive or weedy in some areas, throwing out suckers from the fibrous rootstock, to rapidly colonise an area. Once established they can be extremely difficult to eradicate. On the other hand, they can take some time to become established.
