Zantedeschia 'Red Alert' elevates the traditional calla lily to new heights with its dramatic, funnel-shaped, deep orange-red spathes that emerge above unusually large, glossy leaves peppered with white spots and occasional splashes of red.

This clump-forming beauty bears sculptural flowers making bold statements in both garden designs and cut flower arrangements. Perfect for adding tropical drama to sheltered gardens or large containers, this tuberous perennial brings exotic flair to contemporary plantings, though it demands sharp drainage and winter protection to perform at its spectacular best.


  • Garden care:
    Plant the tubers 7-10cm (3-4in) deep and 30cm (12in) apart into reliably moist, rich soil or good-quality potting compost. Water sparingly until new shoots start to emerge and then start to water more regularly. Best grown as a tender, summer interest plant, this calla lily can be protected from cold in a sheltered, frost-free spot during the winter.
    • Humans/Pets: Harmful if eaten; skin/eye irritant
