Growing Guide: How to Grow Tuberose (Polianthes)

Tuberose, scientifically known as Polianthes tuberosa, is a fragrant and ornamental flowering plant native to Mexico. It is highly prized for its exquisite and intoxicating fragrance, which is often used in perfumery.

Summertime Fragrance

We typically link the most delightful floral scents with springtime, but the summer season can also bring its own fragrant charm. One of the finest plants to achieve this aromatic beauty is the majestic Polianthes, commonly known as the Tuberose. It's important not to confuse it with the Polyanthus Primula, as despite the similar names, their growth patterns and blossoms differ greatly. The Tuberose stands tall, an elegant bulbous plant adorned with pink or white blooms. Its fragrance evokes memories of Gardenias, and in the past, it served as a prominent ingredient in perfumes. However, its connection with humanity spans back through history.

Cultivating Tuberoses in Pots

Opting to cultivate your Polianthes in containers is an excellent strategy for maximising their delightful fragrance! By situating these pots on your patio, you can enjoy the enchanting scent without it having to disperse throughout your entire garden before reaching you. To embark on this endeavour, your initial step is to locate the appropriate containers.

How to Plant:

  • Plant tuberose bulbs in spring after the threat of frost has passed.
  • Place the rhizomes 2 to 4 inches (5-10 cm.) deep and 6 to 8 inches (15-20 cm.) apart in well-draining soil in a sunny location.
  • Ensure the soil remains consistently moist, especially during the late summer blooming period.
  • Improve poor soil quality by adding compost and organic amendments to enhance drainage and texture for better tuberose flower growth.

Caring for your Tuberose

  • Once the tuberose blooms have faded, and the foliage turns yellow, it's time to dig up the bulbs for winter protection.
  • Tuberose care guidelines may differ regarding whether you can leave the bulbs in the ground during the winter.
  • To store Tuberose bulbs during winter, maintain a temperature range of 21-24 C as suggested by most tuberose care advice. Alternatively, you can air dry the bulbs for seven to ten days and then keep them in a cool place at 10 C for replanting the following spring.
