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.
Polianthes tuberosa, the tuberose, is a perennial plant related to the agaves, extracts of which are used as a note in perfumery. The common name derives from the Latin tuberose, meaning swollen or tuberous in reference to its root system.
When blooms are spent and foliage is yellowed, bulbs must be dug up and stored for winter protection in northern areas. Tuberose plant info varies as to which gardening zones can leave the bulbs in the ground over the winter. All recommend spring planting, but autumn digging and storage are said by some to be necessary for all but zones 9 and 10.
