How to grow

Cultivation

Use as summer bedding, planting in a moist, humus-rich, but well-drained soil in full sun. Lift and store overwinter in trays of peat-free compost in a cool, frost-free garage or shed and plant out tubers in spring after risk of frost has passed. Alternatively, grow in containers of peat-free, loam-based John Innes No2 potting compost and overwinter in a greenhouse or conservatory. See Zantedeschia cultivation

Propagation

Propagate by division in spring or propagate by seed, at 21-27°C (70-81°F) when ripe but flowers may not appear for 2 or 3 years.
