Polianthes tuberosa
species of plant
Polianthes tuberosa, the tuberose, is a perennial plant in the family Asparagaceae, subfamily Agavoideae, extracts of which are used as a note in perfumery. Now widely grown as an ornamental plant, the species is native to Mexico.
Etymology
The common name derives from the Latin tuberosa through French tubéreuse, meaning swollen or tuberous in reference to its root system.
Description
The tuberose is herbaceous, growing from underground tubers or tuberous roots. It produces offsets. The leaves are a dull green and about 1–1.5 ft (30–50 cm) long and up to 0.5 in (13 mm) wide at the base. They are slightly succulent. The inflorescence is a spike, reaching up to 3 ft (1 m) high, with pure white waxy flowers. The flowers are tubular, with a tube up to 2.5 in (6 cm) long, separating into six flaring segments (tepals) at the end, and are strongly fragrant. There are six stamens, inserted into the tube of the flower, and a three-part stigma.

Why this record matters
“Polianthes tuberosa” is worth following because a concise public description often conceals a longer documentary argument. Here, Polianthes, tuberosa and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q17270998. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
