Zantedeschia aethiopica

Zantedeschia aethiopica, more commonly known as the Arum lily, is an elegant perennial rhizome native to Africa.  Arum lilies are very popular as cut flowers, and are often incorporated into bridal bouquets on account of their enchanting trumpet-shaped flowers that come in a range of vibrant colors.  Unlike most flowers, arum lilies do not drop their petals when they die; instead they roll into a tube and turn green.  Deadheading is recommended for arum lilies, as it can encourage the growth of more blooms.  Arum lilies are a unique type of plant called a rhizome, which gets its name from the rhizome stem that grows underground.  This differentiates the arum lily from true lilies, which grow from a bulb, and allows them to be more resilient to being cut down.  As a result, the arum lily is very difficult to completely remove and has become invasive in many places like Australia and California.  

In exceptionally warm climates, plant arum lilies in a partially shaded area; otherwise, they prefer a spot with lots of direct sunlight.  Loose, well-draining soil rich in organic matter is ideal for arum lilies.  Maintaining moist soil is important when growing arum lilies, so experiment with watering frequency to find a regular cycle that works for you.  Arum lilies should be fertilized monthly during the growing season to encourage larger and more abundant blooms.  After flowering has ceased, the arum lily will require a period of dormancy. While dormant, it is recommended to limit watering and allow the plant to die back.  If the plant is potted, then move it into a cool, dark space after the foliage has died, and store it there for 2-3 months.  In warmer climates, arum lilies can be left in the ground year-round, but they benefit from being dug up and stored in a cool area.  In particularly cold climates, dig up the rhizome in the fall and gently remove any soil.  Give the rhizomes a few days to dry out and then store them in peat moss in a dark, dry, cool place until spring warmth returns.
