The lily-like Polianthes, often called Tuberose, is neither a lily nor a rose, however its clusters of large trumpet-shaped white flowers which bloom on tall (up to 90cm or 3ft) stalks, do look a lot like lilies. Polianthes also exudes a glorious fragrance that’s been used in perfume for centuries, which will further enhance beds or borders when it flowers in the second half of summer. The same double gift of fragrance and beauty will be taken to vases when it’s used as a cut flower. Polianthes should be planted in all-day sun as it comes from Mexico’s warm climate, where it was called the Ivory Flower. Enrich soil if it’s poor, and make sure drainage is good before planting Tuberose bulbs.
