Noteworthy Characteristics

False rue anemone is a tuberous-rooted, native Missouri wildflower which typically grows 5-8" tall and occurs on open wooded slopes, river flood plains, rich woods and thickets. It is often seen growing in large colonies. Features white, anemone-like flowers (1/2" diameter) with 5 petal-like sepals and showy yellow center stamens. Flowers appear in early spring atop slender stems mostly arising from the leaf axils. Commonly called false rue anemone because the flower is almost indistinguishable from the native Missouri rue anemone (Anemonella thalictroides. Compound, basal leaves are divided into 3-lobed leaflets, usually 2 times ternately divided (specific epithet of biternatum is Latin for twice ternate). Deeper leaflet lobes help distinguish this plant from Anemonella.

Problems

No serious insect or disease problems.

Garden Uses

Best for woodland, wildflower or native plant gardens. May be used in shaded areas of the rock garden for early spring bloom.
