Aerial shoots 30-100(-110) cm, from caudices, rarely with ascending rhizomes, caudices ascending to vertical. Basal leaves 1-5, ternate; petiole 5-35 cm; terminal leaflet sessile or nearly so, oblanceolate to obovate, 2-9(-12) × 2-5(-7) cm, base cuneate to broadly cuneate, margins coarsely serrate and incised on distal 1/2, apex acuminate to narrowly acute, surfaces pilose, more so abaxially; lateral leaflets usually 1-2×-lobed or -parted, occasionally unlobed; ultimate lobes 10-30(-40) mm wide. Inflorescences (1-)3-9-flowered cymes; peduncle villous; primary involucral bracts 3(-5), secondary involucral bracts 2(-3), (1-)2-tiered, ternate, ±similar to basal leaves, bases distinct; terminal leaflet ±sessile, elliptic to oblanceolate, 2-10(-12) cm (2 cm in secondary involucre) × 2-5(-7) cm, bases cuneate, margins coarsely serrate and incised on distal 1/2, apex acuminate to narrowly acute, surfaces pilose, more so abaxially; lateral leaflets unlobed or 1×-lobed or -parted; ultimate lobes 8-25(-35)mm wide. Flowers: sepals usually 5, green, yellow, or red (rarely white or abaxially green to green-yellow and adaxially green or yellow and tinged red), oblong, ovate, or obovate, 6.5-20 × 2.5-10mm, abaxially hairy, adaxially glabrous or nearly so; stamens 50-70. Heads of achenes oblong-ellipsoid, rarely obconic; pedicel 13-25(-30) cm. Achenes: body obovoid, 2-3.7 × 1.5-2mm, not winged, densely woolly; beak curved, 1-1.5mm, puberulous, not plumose. See C. S. Keener et al. (1995) for an analysis of infraspecific variation within Anemone virginiana from which the current treatment has been adopted. Varieties of Anemone virginiana used medicinally by native Americans were not specified; the species was used as an antidiarrheal, an aid for whooping cough, a stimulant, an emetic, a love potion, a remedy for tuberculosis, and a protection against witchcraft medicine (D. E. Moerman 1986).

Much like A. cylindrica, averaging coarser and more loosely hairy; primary lf-segments rhombic-ovate, with the margins toothed or incised to below the middle and ±convex toward the base; involucral lvs 3; peduncles mostly 1-3, some of them often with a 2-lvd secondary involucre; sep greenish-white or less often pure white; seldom red, 7-13(16) mm; fruiting head ovoid, 1.5-3 cm; achenes densely woolly; style 1-1.5 mm, short-hairy, often ±spreading; 2n=16. Dry or open woods; e. Que. to N.D., s. to Ga., Ala., and Ark. June-Aug. Some plants from the n. part of the range diverge toward A. cylindrica in their somewhat narrower heads and in having the lf-segments more cuneate below. These have been segregated as var. alba A. W. Wood or A. riparia Fernald, but they do not appear to be sharply separable from A. virginiana.

From Flora of Indiana (1940) by Charles C. Deam
Infrequent to frequent throughout the state. This is a woodland species and is rarely found in the open along roads and railroads. It generally grows in dry soil on wooded slopes and has a decided preference for slopes along streams. The species varies considerably in the length of its stamens and in the size, shape, texture, and color of its sepals. Some of the variations have been given names but after a careful study of my 77 specimens from all parts of the state I have decided that the characters are too variable to be of taxonomic value.

Indiana Coefficient of Conservatism: C = 4

Wetland Indicator Status: FACU

Diagnostic Traits: SImilar to A. cylindrica, but leaf-like cauline bracts 2-3 and fruiting head to 1.7 cm thick, ovoid to thick-cylindric, up to 2.5 times as long as thick.

Current treatments recognize two varieties in Indiana. Var. alba has anthers 0.7-1.1 mm long, smaller heads (to 1.1 cm thick), and ascending styles. Var. virginiana anthers are 1.2-1.6 mm, the heads to 1.7 cm thick, and horizontally divergent styles.
