Calla/Zantedeschia Black Beauty

Zantedeschia, also known as calla lily, is best planted in spring after the risk of hard frost has passed. Start the rhizomes in pots indoors from early spring, then move them outside once the weather is reliably mild.

Yes. Calla lilies are excellent container plants. Use a large pot with drainage holes, a moisture-retentive compost and a sunny or lightly shaded position. Keep the compost evenly moist while the plant is actively growing.

Leaves naturally yellow and die back when the plant enters dormancy after flowering. If yellowing happens while the plant is actively growing, check that it is not sitting in waterlogged compost and that it is receiving regular water and feed.

This depends on the type. Some calla lilies can remain outside in mild areas, while many need lifting or moving under cover before frost. Check the product details and keep tender rhizomes in a cool, frost-free place over winter.

Calla lilies need warmth, bright light and steady moisture to flower well. Poor flowering is often caused by planting too early into cold soil, lack of sun, dry compost or frost damage to new growth.
