Plants perennial, clumped and taprooted, or mat-forming and long-creeping rhizomatous. Stems: flowering shoots often decumbent proximally, 5-20(-30) cm, glandular-pubescent distally, pilose-subglabrous, deflexed or spreading proximally; non-flowering shoots present; small tufts of leaves present in axils of proximal leaves. Leaves not marcescent, sessile, ± spatulate proximally; blade linear-lanceolate to lanceolate or narrowly oblong, 4-30 × 0.5-6 mm, apex acute, rarely obtuse, subglabrous to softly pubescent, sometimes glandular. Inflorescences lax, 1-20-flowered cymes, pubescence short, glandular; bracts lanceolate, margins narrow, scarious, glandular-pubescent. Pedicels curved just below calyx, 5-30 mm, 1-6 times as long as sepals, glandular-pubescent. Flowers: sepals narrowly lanceolate to lance-elliptic, 3.5-7 mm, margins narrow, softly pubescent; petals obovate, 7.5-12.5 mm, ca. 2 times as long as sepals, apex 2-fid; stamens 10; anthers 0.8-1.1 mm; styles 5. Capsules cylindric, curved, 7.5-11.5 × 2.5-4 mm, (1-)1.5-2 times as long as sepals; teeth 10, erect, margins convolute.

Rocky, gravelly, or sandy places, especially in calcareous or magnesian soils, often a weed in abandoned fields and meadows; throughout most of the north-temperate and boreal regions. Apr.–Aug. Highly variable, and often segregated into numerous confluent spp. or vars. (C. campestre; C. oreophilum; C. strictum; C. velutinum) An extremely villous phase on serpentine in se. Pa. and ne.
