The Q&A Archives: Growing Calla Lilies

Question: Can I grow calla lilies outside in my garden here in Massachusetts?

Answer: Calla lilies (Zantedeschia) are tender plants and will not survive outdoors over the winter in cold regions like yours, so many northern area gardeners keep them as potted plants. They can be set outside for the summer, or can even be planted in the ground in a partially shady location for the summer, but need to be dug and brought inside before frost. Callas also take "a rest" after blooming--they need that rest in order to bloom again. Calla rhizomes should be planted about two inches deep. They like rich soil and plenty of moisture.
