Arum Lilies (zantedeschia) are flowering, herbaceous plants that are native to South Africa. Although they are not true lilies, these hardy, exotic perennials have lush green leaves and large, cream-colored flowers. Arum can grow up to a height of 3 feet and 18 inch spread and come in a large array of colors. They grow hardly in USDA Zones 8-10 and will make beautiful addition as a border or container plant.

Arum lily are grown from rhizomes (tubers) and prefer partial shade in warmer climates but will tolerate full sun in cooler climates. They thrive in loose, well-draining soil that is consistently moist. They should be planted outdoors in late spring after the soil has warmed. They grow exceptional well in containers (indoors or outside) and are virtually maintenance free if given the right conditions (mulching is recommended to retain moisture). They will benefit from a monthly application of fertilizer.  After flowering has ended, their watering should be stopped to allow the plant to die back (in ground). If grown in container, after flowering is over, stop watering for several months and move the container to a shady spot.

If you are growing Arum Lilies in cold climates, the rhizomes should be lifted and dried or a couple of days then brought indoors to store in a cool, dry and dark space overwinter.
