Calla Lily 'Schwarzwalder' is a deep maroon-black variety with a velvety texture, creating a dramatic contrast against its dark green, speckled foliage. The chalice-shaped blooms are highly sought after in floral arrangements for their bold, exotic appeal. Blooming in midsummer, this variety thrives in full sun to part shade with organically rich, consistently moist, well-drained soil. Hardy in USDA zones 9 to 11, it is often grown as an annual in cooler climates, with bulbs lifted and stored for winter. 'Schwarzwalder' is deer-resistant and performs well in containers, borders, and cut flower displays.
