Extremely aggressive in the garden, here in the northeastern US. This native plant may not be a threat to the environment, but it's difficult to control in the garden.

Numerous citrine-yellow cup shaped flowers bloom on strong upright stems high above the green vine like leaves. As the leaves age, they turn to chocolate-brown. Easy to grow.

Perennial Anemone from the USA. Has mid-green, palmate leaves divided into 3 leaflets which are deeply dissected. Bears small, white, sometimes very pale green tinged, saucer shaped flowers under 1 inch across.

Flowers May - July

Likes moist, well drained, humus rich soil in full sun or partial shade. Isn't phased by neglect and is great in a light woodland setting.

Has fluffy seedheads in early Autumn and can get a little weedy if left to its own devices for too long.
