Calla 'Red Alert' (1 rhizome)
It produces abundant blooms in brilliant colours that energize flower beds and containers. Its decorative foliage enhances its tropical appeal.
Red Alert Calla Lily (Zantedeschia ‘Red Alert’) is a rhizomatous perennial distinguished by its intense red, cup-shaped flowers, sometimes highlighted with warm orange tones. Held on upright stems, the blooms create an elegant, vibrant silhouette above glossy green foliage that is often speckled with white. From June to August, this luminous flowering display brings warmth and energy to summer landscapes, while the decorative foliage enhances the plant’s tropical appearance. Reaching 45 to 60 cm in height, it quickly draws attention in flower beds and containers. Hardy only to Zone 10, it must be protected from frost in Quebec.
Plant the rhizomes in spring after all danger of frost has passed and the soil has warmed sufficiently. Choose a location in full sun or partial sun with rich, fertile, evenly moist, and perfectly drained soil. Lay the rhizomes flat, 8 to 10 cm deep, and space them 30 to 40 cm apart. Water regularly to maintain consistent moisture without allowing the soil to become waterlogged. An annual application of compost and a balanced fertilizer every two weeks encourage abundant flowering. Before the first frost, lift the rhizomes and store them in a cool, dry place.
‘Red Alert’ calla lily is ideal for summer flower beds, borders, patios, large containers, and bouquets. For container growing, choose a pot at least 30 cm in diameter with excellent drainage. Its red flowers pair beautifully with begonias, cannas, caladiums, coleus, and coral bells to create colourful, dynamic tropical displays. Valued for their excellent vase life, the blooms add intensity and elegance to contemporary floral arrangements. They may also attract some pollinators. However, the flowers are grown exclusively for ornamental purposes and are not intended for consumption.
