Plant Zantedeschia 'Schwarzwalder' Calla Lily in spring, and in midsummer, it blooms in huge, exotic, black-maroon flowers on tall, elegant stalks sheathed in long, dark green leaves speckled with white spots. Highly popular in the floral industry, the chalice-like flowers make superb cuts for bouquets and arrangements.
A Zantedeschia hybrid, commonly called calla lily, 'Schwarzwalder' is a tender, rhizomatous perennial, often grown as an annual. It has an upright habit, and although it makes a gorgeous specimen plant, it is shown to best effect when massed or grouped. Calla lily grows equally well in garden or container, outdoors or indoors. The flowers are sterile and will not seed.
Easy to grow and virtually trouble-free, calla lily grows best in sunny to partly sunny locations with organically rich, consistently moist, well-draining soil, with best flowering in full sun. In hot summer climates, provide full morning sun and filtered afternoon shade. The plants benefit from regular watering and feeding with a liquid fertilizer high in potash.
