Arum lily is a species in the family Araceae, native to southern Africa in Lesotho, South Africa, and Swaziland. It grows to 0.6–1 m (2–3 feet) tall, with large clumps of broad, arrow shaped dark green leaves up to 45 cm (18 in) long. The Inflorescences are large, produced in spring, summer and autumn, with a pure white spathe up to 25 cm (10 in) and a yellow spadix up to 90 mm (3½ in) long.
Arum lilies make striking architectural plants with large, glossy foliage which, in late spring and early summer, is joined by large, white, hood-shaped flowers. The plants grow beside water, in shallow pond margins or a bog garden, where they associate well with other water plants.
