Habit | Plants perennial, forming open mats, glabrous; stolons slender, 0.4–1.3 mm when dried. | Plants perennial, tufted, glabrous proximally, glandular-pubescent distally. |
Stems | extensively stoloniferous, with dense terminal rosettes. |
vertical, branched, glandular, bearing dense terminal rosettes. |
Flowering shoots | erect; simple, 3–14 cm; stem leaves alternate, spatulate-oblong or elliptic-oblong; widest at or below middle, different from rosette leaves. |
recurved when young; simple, 13–30 cm, glandular pubescent; stem leaves oblong-oblanceolate, bases not spurred. |
Leaves | rosette leaves spreading, usually nearly parallel to ground, usually forming flat rosettes, spatulate, narrowing to petioles, 7–19 × 4.5–10 mm, 5 × as wide as thick, green or pruinose and white, bases not spurred, not scarious, sometimes muricate or papillose near margins; tips rounded or truncate; surfaces usually glaucous. |
rosette leaves ascending, oblong-spatulate, laminar, 14–40 × 9–32 mm, green, bases not spurred; tips widely rounded to obtuse or notched; surfaces with papillose-crenulate appendage, glaucous when young; basal leaves much wider than thick; proximal leaves glabrous; distal leaves glandular-hairy. |
Inflorescences | cymes with ~30 flowers, 3-branched; branches forked; bracts oblong-spatulate or linear. |
cymes with 20–30 flowers; (2)3-branched, glandular; branches not forked. |
Flowers | 5-parted; sepals spreading to erect, lanceolate, linear-lanceolate, oblong-ovate or obovate; ~2.5 × 1.5 mm, green to yellow-green; tips acute or obtuse; surface glaucous or pruinose; petals strongly spreading above erect base, linear to oblanceolate, 4.5–9 mm, yellow; tips acute; filaments yellow; anthers yellow. |
5-parted; sepals erect; ovate or lanceolate, 4–8.5 × 3–4.5 mm, 40% as long as petals, green; tips obtuse to acute, glandular-pubescent; petals erect, connate basally, oblong-lanceolate, 12–16 mm, yellow; tips aristate, glandular-pubescent; filaments greenish yellow; anthers yellow. |
Fruits | erect until mature then spreading, fused basally, brown. |
somewhat divergent when mature, fused basally, brown. |

Distribution | ||
Discussion | Rocks, cliffs and road cuts. Flowering Apr–Aug. 0–2400 m. Casc, Col, CR, ECas, Est, Sisk, WV. CA, WA; north to British Columbia. Native. Sedum spathulifolium is highly variable. If subspecies are recognized, most of our plants are S. spathulifolium ssp. spathulifolium. A coastal form with thick, white-pruinose leaves, short, stout stolons, dense inflorescences and thick, crowded stem leaves can be called S. s. ssp. pruinosum (if it is considered a strictly coastal entity). If it is considered to include strongly glaucous or pruinose plants of the Coast Range that are less dense in growth form, the name S. s. var. minus would be applied. Plants with thin, green leaves, numerous long, slender stolons that tend to grow upwards before growing out, paler flowers, and more spreading follicles can be called S. s. ssp. purdyi, a rare form known only from southern Josephine County, and Del Norte and Siskiyou counties in California. |
Steep serpentine slopes and rock outcrops. Flowering May–Jul. 100–300 m. Sisk. Native. Endemic to Oregon. Sedum moranii is distinctive with its usually three-branched inflorescence and densely glandular sepals, petals, and inflorescence. This species is extremely rare, known only from a short stretch of the Rogue River. |
