This native perennial wildflower is 4-8" tall. A non-flowering plant produces a whorl of trifoliate basal leaves on slender stems; each basal leaf typically has 3 leaflets on a long slender petiole. The basal stems are light green to reddish purple, unbranched, terete, and hairless; the stems of flowering plants are similar. Individual leaflets are up to 1½" long and 1" across; they are obovate or broadly oblong in shape. The outer margin of each leaflet has 3 blunt lobes, otherwise the margins are usually smooth. Sometimes there are 1-2 blunt teeth along the outer margin of a leaflet. The upper surface of each leaflet is medium green to purplish green and hairless, while the lower surface is pale green and hairless. A reticulate network of veins is conspicuous on the lower surface. At the base of each leaflet, there is a [Three Flowers] slender stalk (petiolule) about ¼" long. Toward the middle of its stem, a flowering plant sometimes produces a whorl of cauline leaves that resembles the whorled basal leaves. At its apex, this stem terminates in a whorl of trifoliate leaves or simple leaflets (sometimes including a combination of the two). These terminal leaves and leaflets resemble the leaves and leaflets of the basal and cauline leaves. Immediately above the terminal leaves or leaflets is a loose umbel of 1-5 flowers. The slender pedicels of the flowers are up to 1½" long. The diurnal flowers are ½–1" across; the central flower is usually a little larger in size than any lateral flowers. Each flower has 5-10 petal-like sepals, a dense cluster of small green pistils in the center, and a ring of conspicuous stamens. The petal-like sepals are white or pinkish white, while the stamens have white filaments and yellow anthers. There are no true petals. The blooming period occurs from mid- to late spring for about 3 weeks. Each flower is replaced by a cluster of 4-15 achenes. Each achene is about 1/3" in length, terminating in a slightly hooked beak. Inside each achene, there is a single seed. The root system consists of fibrous roots; the upper roots near the base of a plant are somewhat fleshy and swollen. This wildflower spreads by reseeding itself.
Habitats include mesic to dry deciduous woodlands, wooded slopes, and thinly wooded bluffs. This native wildflower is usually found in above-average to high quality woodlands where the original ground flora is largely intact. This one was photographed at the Savannah River Bluffs Heritage Area in North Augusta (Aiken County), SC.
Rue Anemone is one of many showy wildflowers that develop in deciduous woodlands during the spring. Both the flowers and foliage are quite attractive. Because the flowers move around easily in the wind, it is sometimes called 'Windflower.'
