Sedum glaucophyllum

Herbs, perennial, cespitose, glabrous. Stems creeping, much-branched, forming terminal rosettes on branches (primary rosettes usually 1–2.7 cm diam.). Leaves alternate, spreading to ascending, petiolate; blade pale green or blue-green, usually glaucous, oblanceolate to spatulate, laminar, (6–)10–18 × 1–4.5 mm, base petiolelike, with simple, short spur, not scarious, apex obtuse, (surfaces papillose). Flowering shoots erect, simple, 3.5–17.5 cm; leaf blades narrowly oblong to linear, base short-spurred; offsets not formed. Inflorescences cymes, 5–30-flowered, 3-branched; branches erect or only slightly recurved, sometimes forked; bracts similar to leaves, smaller. Pedicels absent. Flowers 4-merous; sepals divergent, distinct, green, linear-lanceolate, unequal, 3.6–6.3 × 0.9–1.6 mm, apex obtuse, (papillose); petals spreading, distinct, white, lanceolate, minutely hooded, 4–9 mm, apex acuminate; filaments white; anthers dark red to almost purple; nectar scales white, subquadrate. Carpels widely divergent in fruit, slightly connate basally, brown. 2n = 28, 44, 45–49.

Phenology: Flowering late spring-mid summer.
Habitat: Usually shaded cliffs, crest of cliffs, rocky slopes, on limestone, shale, sandstone, granite, hornblende gabbro, schist, and gneiss rocks

Discussion

Sedum glaucophyllum is known only from the central and southern Appalachian Mountains. According to A. S. Weakley (2007), reports from Georgia are based on confusion with S. nevii.
