Detailed Information

Flower: Flower shape: 5-petals

[photo of flowers] A single 1-inch flower on a hairy stalk arises from a whorl of leaves at the end of the stem. Flowers have 4 to 9 petal-like sepals, usually 5, with numerous white-tipped stamens surrounding a green center. Flower color is usually white, occasionally pink.

Leaves: Leaf attachment: whorl Leaf type: compound Leaf type: lobed

[photo of leaves] Leaves are compound in groups of 3, though the lateral leaflets may be cleft so it appears to be 4 or 5 leaflets. A single whorl of 3 stalked leaves sits at the top of the stem with the flower stalk arising from the center. Leaflets are up to 1½ inches long, notched, lobed or deeply divided in 2 or 3 parts, coarsely toothed at the tip end, wedge-shaped at the base, and very short-stalked or stalkless. Leaf color ranges from bright green to purplish green to dark purple. A single basal leaf similar to the stem leaves, but nearly round in outline, may also be present. Leaves and stems are covered in fine hairs.

Fruit: Fruit type: seed without plume

[photo of fruit] Fruit is a round head of beaked, oval seeds, each 1/8 to 1/6 inch long, variously hairy and the beak straight or curved.

Notes:

Wood Anemone tends to grow in thick mats, spreading via rhizomes. A single plant may take 5 years or longer to flower, so often only a few flowers are seen among the leaves. When not flowering it can be recognized by the basal leaves, nearly round in outline, with 3 hairy, nearly stalkless leaflets, the lateral leaflets often deeply cleft. There are 2 recognized varieties: var. minima has a limited range in NC, TN, VA, WV; var. quniquefolia ranges from Nova Scotia to southern Manitoba and south to Alabama, and is found in Minnesota.

I have these growing in my yard. Very delightful in Spring. They disappear in summer.

I always thought this was a purple plant. Does anyone know of a similar flower in purple?
