Habit | Herbs, biennial, erect, glabrous. | Herbs, annual, tufted, glabrous or scattered glandular-hairy. |
Stems | rootstocks, horizontal, simple, bearing basal rosettes (axillary shoots with subterranean, white stems that detach easily and bear terminal rosettes of colorless leaves). |
erect or ascending, simple or much-branched, (glandular-hairy), not bearing rosettes. |
Flowering shoots | erect, simple, (5–)11(–18) cm; leaf blades ovate or elliptic, base not spurred; offsets not formed. |
spreading or erect, simple, 5–15 cm, (glabrous or with scattered glandular hairs); leaf blades linear to oblong, base not spurred; offsets not formed. |
Leaves | alternate, spreading, outermost ones petiolate (petiole 4–5 mm); blade green or greenish white, not glaucous, oblanceolate, obovate, or narrowly spatulate, laminar, 2–16 × 1.4–3.2 mm, base not spurred, not scarious, apex blunt, (surfaces papillose). |
alternate, ascending, sessile; blade green, sometimes glaucous, linear to oblong, semiterete or ± laminar, 4–20 × 1–2 mm, base not spurred, not scarious, apex obtuse, (surfaces usually glabrous or, rarely, glandular-hairy). |
Inflorescences | cymes, 5–60-flowered, 3–6-branched; branches often strongly recurved, each 1 or 2 times dichotomously forked; bracts similar to leaves, smaller. |
lax to ± dense cymes, 2–8-flowered or flowers solitary, 2–4-branched; branches not recurved, not forked; bracts similar to leaves, smaller. |
Pedicels | to 0.3 mm. |
to 0.5 mm. |
Flowers | (5–)6(–7)-merous; sepals erect, slightly connate basally, green, ovate, equal, 1.5–2 × 0.7–1.1 mm, apex acute; petals spreading, distinct nearly to base, canary yellow, keel green or dark red, lanceolate to oblong, carinate, 4–6 mm, apex subobtuse to acute; filaments yellow; anthers yellow; nectar scales deep yellow, subquadrate. |
5–9-merous; sepals erect, connate basally, green, broadly triangular, equal, ca. 2 × 1 mm, apex acute, (glandular-pubescent); petals spreading, distinct, white with pinkish midvein, lanceolate, not carinate, 4–5(–7) mm, apex narrowly acuminate; filaments white; anthers dark purple; nectar scales white, spatulate-quadrate. |
Carpels | stellately spreading in fruit, connate basally, brown. |
stellate-spreading in fruit, connate basally, white or pale pink. |

Discussion | Variation in the number of floral parts of Sedum leibergii (5–7-merous) is unique in North American sedums. It has tiny rosettes of lax, long-spatulate basal leaves that mostly have shriveled by anthesis. Sedum borschii, which is often confused with S. leibergii, has primary rosettes, prominent at anthesis, that have obovate or elliptic leaves.

Sedum hispanicum has been naturalized in North America since 1880; it is sometimes cultivated. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
