How to grow gloriosa

Do it:

Mar, Apr, May

Takes just:

30 minutes

The climbing glory lily, Gloriosa rothschildiana is an ideal choice for growing in a warm conservatory, where it will scramble up support canes or wires to a height of around 1.2m. An exotic summer-flowering plant, the glory lily requires warm growing conditions to encourage the tubers to develop roots. Plant them in pots and keep them in a heated greenhouse or propagator.

Before planting, study each tuber closely to see which end has a shoot growing out from the tip. These shoots are the plant's leaves, so should be facing upwards. If no shoots are visible, plant the tubers horizontally in trays and transplant later when you know which end the shoots are growing from.

You will need

  • Glory lily tubers, Gloriosa rothschildiana
  • Multi-purpose, peat-free compost
  • 20cm diameter pot
  • String
  • Support

Place the tubers in a large, deep pot and fill with compost so the shoot tips lie a few centimetres below the surface. Each tuber produces a single shoot, so plant several in each pot.

Stand the pot in a warm spot, such as in a heated greenhouse or on a heated propagator, and keep the compost moist.

When upright, leafy shoots form, tie them to supports. The leaf tips have hooked ends that will attach to things, but don't rely on these as the only means of support. The shoots will branch out and produce spectacular flowers in midsummer.
