The tuberose (Polianthes tuberosa) is a perennial plant related to the agaves, extracts of which are used as a note in perfumery.
The tuberose is a night-blooming plant native to Mexico, as is every other known species of Polianthes. It grows in elongated spikes up to 45 cm (18 in) long that produce clusters of fragrant waxy white flowers that bloom from the bottom towards the top of the spike. It has long, bright green leaves clustered at the base of the plant and smaller, clasping leaves along the stem. Epiphyllous adhesion of stamens is seen in the flower.
