It is a late blooming perennial that does well in evenly moist soil in sun or light shade. Japanese anemones
are hardy in USDA hardiness zones 4 through 8. Japanese anemone looks best planted with other
perennials or ornamental grasses that can help to give it some support since it tends to flop over
when it begins to flower. You can find 'King Henry' Japanese anemone growing in the entrance area
of the National Herb Garden and near the entrance of the National Bonsai & Penjing Museum.
