Plants perennial; taproot slender; caudex decumbent, branched, producing tufts of leaves and erect flowering shoots. Stems simple proximal to inflo-rescence, 20-80 cm, glandular-pubescent, often subglabrous near base. Leaves: basal numerous, tufted, petiolate, petiole ciliate, blade oblanceolate, 3-10 cm × 8-18 mm, base spatulate, apex acute to obtuse, glabrous on both surfaces, rarely puberulent; cauline in 2-4 pairs, broadly petiolate to sessile, reduced distally, blade oblanceolate to narrowly elliptic or lanceolate, 1-10(-30) cm × 4-16(-30) mm, margins ciliate, apex acute, shortly acuminate, glabrous. Inflorescences open, with ascending, often elongate branches, (3-)7-11(-20)-flowered, bracteate, glandular-pubescent, often densely so, viscid; bracts leaflike, lanceolate, 4-40 mm. Pedicels erect in flower, sharply deflexed at base in fruit, 2-1 times length of calyx. Flowers: calyx green to purple, 10-veined, tubular to narrowly obconic in flower, 16-22 × 5-6 mm, clavate and swelling to 7-12 mm in fruit, glandular-pubescent, lobes lanceolate to oblong, 3-4 mm, margins usually narrow, membranous, apex acute or obtuse; corolla scarlet, 2 times longer than calyx, clawed, claw ciliate, gradually widening into limb, longer than calyx, limb obtriangular to oblong, deeply 2-lobed with 2 small lateral teeth, 10-14 mm, glabrous or nearly so, appendages 2, tubular, 3 mm; stamens exserted, shorter than petals; styles 3(-4), equaling stamens. Capsules ovoid, equaling calyx, opening by 3 (or 4) teeth that sometimes split into 6 (or 8); carpophore 2-3(-4) mm. Seeds ash gray, reniform, 1.5 mm, with large inflated papillae. 2n = 48. Flowering spring. Deciduous woodlands, bluffs, moist wooded slopes; 200-1300 m; Ala., Ark., Del., Ga., Ill., Ind., Iowa, Kans., Ky., La., Mich., Miss., Mo., N.Y., N.C., Ohio, Okla., Pa., S.C., Tenn., Va., W.Va. Silene virginica is related to the scarlet-flowered species from the southwest, S. laciniata and S. subciliata. It makes a beautiful garden plant in semishaded locations. J. A. Steyermark (1963) recorded the occurrence of a hybrid between S. virginica and S. caroliniana subsp. wherryi in Shannon County, Missouri. Reports of the occurrence of S. virginica in Ontario are based on a collection (CAN, K) made in 1873 from 'islands in the Detroit River' in 'Canada West.'

Perennial herb with a slender taproot 20 cm - 0.8 m tall Stem: unbranched, glandular-hairy, often nearly hairless near base. Inflorescence: an elongate-branched, open cluster of typically seven to eleven flowers, glandular-hairy, sticky, subtended by leaf-like bracts. Flowers: scarlet, twice as long as calyx. Stalk upright. Stamens ten, exserted, shorter than petals. Styles three, as long as stamens. Sepals: fused at the base into a tube (calyx). Calyx tube green to purple, 1.6 - 2.2 cm long, 5 - 6 mm wide, swelling in fruit, tubular to narrowly reverse conic, ten-veined, glandular-hairy, with five short lobes. Lobes 3 - 4 mm long and lance-shaped to oblong with a blunt or pointed tip. Petals: five, scarlet, 1 - 1.4 cm long, blade reverse triangular to oblong, clawed, deeply two-lobed with two small, lateral teeth. Fruit: a dehiscent capsule, opening by three or four (sometimes appearing as six or eight) teeth, equal to calyx, egg-shaped. Seeds ashy gray, about 1.5 mm long, kidney-shaped, roughened. Basal leaves: numerous, stalked, 3 - 10 cm long, 8 - 18 mm wide, reverse lance-shaped to spatula-shaped with a blunt to pointed tip, tufted. Stem leaves: opposite, two to four pairs, stalkless to broadly stalked, 1 - 15 (or more) cm long, 4 mm - 3 cm wide, smaller upward, reverse lance-shaped to lance-shaped with a pointed tip, hairy-fringed.

Occurence in the Chicago region: native

Etymology: Silene probably comes from the Greek word sialon, meaning saliva, referring to the sticky secretion on many of these plants. It may also have come from the word seilenos, referable to Silenus-a foam-covered, drunken character in Greek Mythology. Virginica means "of or from Virginia."
