Information on Calla Lilies

Overview

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.

Identification

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.

Geography

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

Function

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

Warning

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

Caution

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.
