Zantedeschia albomaculata (Spotted Calla Lily)

Native from Nigeria to Tanzania and southern Africa, this herbaceous perennial grows in clumps from underground tubers. Its arrow-shaped leaves are often marked with pale spots. What appears to be a large flower is a modified leaf called a spathe, surrounding a spike of tiny flowers called a spadix. Spathes range from white and cream to pale yellow or pink. It can be propagated by seeds or division. Calcium oxalate crystals can cause burning and swelling if the plant is eaten. Photographed in Colombia.
