Polianthes: Greenhouse Plants

W – warm, minimum of 13°C (55°F) / T – tropical, minimum of 18°C (65°F)

Family: Amaryllidaceae


The first and only time I grew Polianthes tuberosa, commonly called the Tuberose, I had to throw them all away just as they came into flower because they had very bad virus which manifested itself in distortions and yellow lines in the stems and leaves. However, I would not hesitate to try again because they have such beautifully scented white flowers. The bulbs can be potted at any time of year as soon as they are obtained. Most popularly grown is P. ‘The Pearl’ which has many double flowers to a stem. Plant the bulbs 2.5 cm (1 in) deep. If you have several bulbs, try potting them singly and placing them in different temperatures from cool to tropical to get staggered flowering. Bring pots into the warmth as you require them. Make sure the compost they are planted in is well moistened as it is best not to water them again until they begin to grow (obviously one must if they become too dry). They make exquisite and unusual buttonhole flowers.
