Information on Calla Lilies


The calla lily is also called the garden calla and the florist's calla. Propagation of this popular lily is done by removing offsets from the rhizomes.


Calla lilies are perennial plants that grow long leaves and develop cup-shaped flowers in the summer. They can grow to a height of 30 inches.


Calla lilies originated in South Africa, where they fill fields with their blossoms. They enjoy growing in wet marshy places.


Calla lilies are used as houseplants or interiorscapes. They are also found in ornamental landscapes and are used as cut flowers.


Calla lilies are susceptible to soft rot, which is a bacterium that enters into the rhizomes through any wounds during wet conditions.


Calla lilies are highly toxic if eaten. They cause severe burning and swelling of the lips, tongue and throat. Stomach pains and diarrhea can also occur.
