Gloriosa lilies can be grown from tubers or seeds. If growing from seeds it is best to start them off indoors.
The tubers should be planted at a depth of 5 cm (2 inches) and a spacing of 30 cm (12 inches) in mid spring, well after any chance of a frost.
If growing from seed, then first soak overnight in warm water, then sow the seed in peat pots and lightly cover. This should be done in late January or February.
It should take about a month for Gloriosa seeds to germinate at a temperature of 21 to 25 degrees centigrade (70 to 77°F).
Once established, transplant the Gloriosa seedlings outdoors in mid spring.
Plants should be located in a sunny area, and provided with a trellis or similar structure to grow upon. Ideally the soil that they grow in will be humus rich.
Gloriosa species such as climbing lily and Gloriosa lily are climbers, so provide a trellis for support.
They are quite hungry and thirsty, so provide liquid fertilizer and water regularly when they are growing.
Once they have finished blooming, water less frequently.
If you require more Gloriosa plants then propagate by dividing their tubers in mid spring.
