Polianthes Tuberosa The Pearl - Tuberose is a night-blooming plant that is native to Mexico. It blossoms with deliciously scented, double white-pink flowers from August through to November. These late flowering bulbs reach a height of about 80 cm and are a genuinely delightful eye-catcher in the garden when most other bulbs have finished flowering. In the winter, store the bulbs well at 15°C until the time comes for planting them in the spring.
