The exotic looking flowers of the Arum lily (Zantedeschia aethiopica) make it a popular perennial plant for cut flowers. This easy to grow perennial bulb is also a great plant for a border or near a pond. They tolerate a wide range of growing conditions including boggy soils.
Their fleshy, arrow-shaped leaves and flowers can grow up to 3 ft high and the plant is quite fast growing if provided with the right conditions.
Callas come in many varieties and colors. The most common and hardiest one is Zantedeschia aethiopica with its white flowers. You will also find yellow, peach, pink or red varieties. The more compact mini calla lily bulbs ('Little Gem', 'Perle von Stuttgart') are more suitable for smaller flower beds and containers.

Arum lilies like a well drained but moist soil. They tolerate a pH range from 5.5 - 7.5 and like a sunny to semi-shaded position. If you grow calla lilies in a rich, well fertilized soil you will have great results.
Your callas will start flowering during spring until the summer. During this time it is very important that you feed and water the plants regularly! You can use a general purpose organic fertilizer for this. Once the plants have finished flowering stop the feeding and watering. The arum lilies now enter their dormant phase.
If you are growing callas in a container you can repot them during July. Take the root ball out of the pot and shake all the loose soil off the roots. You can also divide the rhizomes during this procedure. Replant the bulbs with fresh potting soil and over-winter them at 50-60 degrees F (10-15 degrees C).
