Near black this is the deepest coloured Calla Lily available. Zantedeschia Black Star boasts dramatic deep maroon spathes standing on dark tube like stems, surrounded by bright green wavy foliage speckled with white. Native to the hot and humid climates of South Africa, the Calla Lily is mostly found by lakes in moist soils, therefore prefers well-drained soil in a full or half sun location. Calla Lilies are dramatic additions to outdoor gardens with their distinctive funnel-shaped blossoms, but also make excellent cut flowers.
