Plant one tuber in 15cm (6") pots 2.5cm (1") deep during March. Water thoroughly and then sparingly until the leaves appear. Maintain a minimum temperature of 15ºC (60ºF). When in growth keep the plants well watered and apply a liquid fertiliser every two weeks. The plants can be moved outdoors once the danger of frost has passed, grow in a sheltered, moderately fertile, well drained soil, in full sun. The plants will reach a height of 60-90cm (2-3'). Once the foliage starts to die back reduce watering and keep them dry while they are dormant. The tubers are not hardy and should be lifted before the first frosts and stored in sand in a frost free place. The tubers only flower once but during the growing season young tubers will have formed. These can be started into growth in spring and will reach flowering size by the end of the growing season. The new tubers will flower the year after planting.
