Source-derived summary

Yucca gloriosa, also known as Spanish dagger, mound lily yucca and other common names, is a species of flowering plant in the asparagus family, native to the southeastern United States. Growing to 2.5 m (8 ft), it is an evergreen shrub. It is widely cultivated as an ornamental for its architectural qualities, and has reportedly become established in warmer climates in the wild in various parts of the world.

Description

Yucca gloriosa is caulescent, usually with several stems arising from the base, the base thickening in adult specimens. The long narrow leaves are straight and very stiff, growing to 30–50 cm (12–20 in) long and 2–3.5 cm (3⁄4–1+1⁄2 in) wide. They are dark green with entire margins, smooth, rarely finely denticulate, acuminate, with a sharp brown terminal spine. The inflorescence is a panicle up to 2.5 m (8 ft) long, of bell-shaped white flowers, sometimes tinged purple or red. The fruit is a leathery, elongate berry up to 8 cm (3 in) long.

Taxonomy

Yucca gloriosa was first described by Carl Linnaeus in 1753. Genetic evidence has shown that the species originated via multiple hybridizations between Yucca aloifolia and Yucca filamentosa.

Editorial summary

Begin with the source’s own compact description: “Yucca gloriosa” is species of plant. The dossier treats that line as a proposition to test through Yucca, gloriosa and species, not as a finished interpretation.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current lead gives the account dated anchors—1753—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Yucca, gloriosa and species is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of plant” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Mar 31, 2026. The linked authority identifier is Q164135. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1753.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
