A rhizomatous perennial forming a tall clump, reaching a maximum size of 6 x 5 ( rarely over 4 ) feet, that is a widespread native to southern Africa.
The broad, arrow-shapped, leathery leaves, up to 24 x 10 ( rarely over 18 ) inches, are glossy luxuriant deep green. It is evergreen in comsistently moist mild climates.
It is drought deciduous in mild climates with a distinct dry season.
The pure white flower spaethes, up to 10 inches in length, have a yellow spadix, up to 3.5 inches in length. They are borne early summer to mid-autumn.
Hardy zones 8 to 9 in full sun to partial shade on moist, well drained soil. They can be grown further north in pots and brought in during winter and stored in a cool basement ( another method of growing it in cold climates is to plant in the ground and dig up the tubers during autumn after the foliage naturally dies back and storing them in potting mix or peat moss in a cool frost free garage or basement ).
Plant the rhizomes 2 inches deep however in colder climates it is recommended to plant them deeper on light soil, up to 6 inches in depth, to prevent freeze damage.
The Common Calla Lily will thrive on consistently moist, well drained soil but can also survive in water up to a foot deep.
It is one of the very few species of Callas that tolerate cooler summers as occur in the British Isles and the Pacific Northwest in North America.
