Plants forming colonies of rosettes, arborescent, to 7 m. Stems 1–3, erect or somewhat declining, simple or sparingly branched. Leaf blade erect, dark green, flattened or slightly concave, thick, 12–40 × 2.5–6 cm, rigid, margins sharply denticulate or entire, rarely filiferous with straight fibers. Inflorescences pendent, paniculate, arising 1/4–1/2 within rosettes, somewhat conical, 4.5–6.1 dm, glabrous or slightly pubescent; peduncle scapelike, to 3 dm. Flowers pendent, to 7 cm; perianth globose; tepals spreading, connate basally for less than 1 mm, creamy white tinged with green or purple near base, lanceolate, 3–4 × 1.2–2.2 cm; filaments ca. 2 cm; anthers 2–3 mm; pistil light green, 3–4 × 0.8–1 cm; ovary stipitate, 2–5 cm; style 5 mm; stigmas distinct. Fruits pendent, baccate, without core, indehiscent, 3.5–5 × 2–2.6 cm, with fleshy, succulent, purple pulp. Seeds dull black, round-ovate, 5–7 mm diam., 2.5 mm thick.

Discussion
Yucca aloifolia has been widely cultivated, and horticultural forms (or varieties, depending upon the source) differ in the striping of yellow and white on the leaves. Results of DNA studies by K. H. Clary (1997) show a close relationship between this species and Y. gloriosa.
