In the garden
Zantedeschia aethiopica 'Crowborough' is a perennial from southern Africa (Lesotho, South Africa, Eswatini) grown for its white spathes that appear from June to September. It typically reaches around 1.0 m and is treated as a summer-flowering clump in temperate gardens. The cultivar sits in the Araceae family and is valued where sustained moisture is available. Plant in a sunny spot where the soil remains wet; acceptable soils include sandy, loamy or clay types so long as they do not dry out. The UK hardiness H4 (average) indicates it will tolerate typical UK winters in most gardens with some protection in exposed sites; it is also suitable for USDA zones 8–10. Positioning at the edge of a pond, in a boggy border or in a container with a consistently moist compost will help it reach the stated height and flower reliably through the summer months. Handle with care: Zantedeschia aethiopica 'Crowborough' is harmful if eaten and a skin and eye irritant, so wear gloves and other protective equipment when planting, dividing or moving clumps. Keep pets away from foliage or cut material and consult the HTA guide to potentially harmful plants for further contact information.
