Polianthes tuberosa
The tuberose is a plant of the agave family Agavaceae. It appears as a rosette of thin leaves up to 45 cm (18 in) long, and puts out a spike of fragrant tubular white flowers in summer.
The common name is the source of some confusion; it derives from Latin tuberosa, meaning swollen or tuberous in reference to its root system, but it has come to be thought of as derived from "tube + rose".
Members of the closely-related genus Manfreda are often called "tuberoses".
