Calla 'Summer Sun' (1 rhizome)

Summer Sun Calla Lily (Zantedeschia ‘Summer Sun’) is a rhizomatous perennial distinguished by its luminous orange, cup-shaped flowers warmed with delicate golden tones. Held on upright stems, the blooms create an elegant silhouette above glossy green foliage that is often marked with small pale spots. From June to August, this brilliant flowering display brings warmth, energy, and exotic appeal to summer landscapes. Reaching 45 to 60 cm in height, the plant maintains a refined appearance in both flower beds and containers. Hardy only to Zone 10, it must be protected from frost under Quebec conditions.

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. Keep the soil consistently moist during active growth without allowing it 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.

‘Summer Sun’ 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 golden-orange flowers pair beautifully with begonias, cannas, caladiums, coleus, and coral bells to create luminous tropical displays. Valued for their excellent vase life, the blooms add warmth and brilliance to summer floral arrangements. They may also attract some pollinators. However, the flowers are grown exclusively for ornamental purposes and are not intended for consumption.
