Description

Commonly called Tuberose, the rhizomatous bulb produces a basal clump of thin leaves that lay flat on the ground and an upright straight stem with a spike of fully double, very fragrant tube shaped white flowers that open like a star. The heady and heavily scented blooms are produced in late summer and are as versatile and long lasting in the garden and container as they are when cut for the vase. They are mildly frost tolerant and will grow best outdoors in sub-tropical to warm temperate climates, but will also perform well in a warmed greenhouse in colder climates.


Cultivation

Tuberoses are warm climate plants, but will tolerate light frosts in the garden and should be grown in full sun in moist, well drained soil. In cooler areas, the bulbs can be grown in containers that can be given shelter over winter. Prepare the growing site by digging over the soil and adding a good handful of blood and bone or rich compost prior to planting out. Plant the bulbs 8 to 10cm deep and 15 to 20cm apart and water in well. Plants will respond well to regular applications of liquid fertiliser and watering throughout the growing season. No particular pests or diseases but protect them from snails and slugs.
