Double Tube Rose

Commonly called tuberose, Polianthes tuberosa is a perennial species of plant grown for its fragrant, creamy white flowers. One double-flowered cultivar called "The Pearl" has been developed for its larger, longer-lasting flowers and smaller size, which tops out at 2.5 feet compared to the 3-foot-tall single-flowered variety. Gardeners in Sunset's Climate Zones 7 to 9 and 14 to 24 can easily grow the double-flowered tuberose cultivar if the plants are provided with four months of warm, frost-free weather and fertile soil. However, in zones 7 to 9, it is best to lift the rhizomes in autumn and overwinter them indoors to avoid potential frost damage.

Delightfully, sweet-scented flowers make 'The Pearl' one of our favorite plants. The Fragrant Double Tuberose has unique pink and green buds that open into double white flowers during the summer. We recommend planting these behind your shorter bulbs for an added dimension in your garden. 8-10cm bulbs. Fragrant Double Tuberoses bloom July and August.
