Etymology: The plant is named for its roots, not its blooms. Its Latin name comes from "tuber," meaning a swelling or lump, and the adjective "tuberosus" describes something knobbly or bulbous. Botanists applied the feminine form "tuberosa" to the plant because it grows from fleshy underground tubers, and the Latin name was later adopted in the scientific naming of the species. English took the name as "tuberose," but the spelling was reshaped by association with "rose," which the plant is not. The flower is in the agave family, closer to the agave and the asparagus than to any rose. Its name thus reflects a change in form rather than a change in meaning. The plant itself is native to Mexico, where it was cultivated long before European botanists gave it a Latin name. The scented white flowers have been prized in perfumery for centuries.
