- Perennial calla lilies, or Zantedeschia aethiopica (L.) Spreng, grow wild in the warm climates of California, Oregon, Hawaii and Puerto Rico. The U.S. Department of Agriculture classifies the flower as a vascular, flowering plant in the Arum family. Since calla lilies do not exhibit any woody tissue above ground and generate from a tuber or rhizome, the plants are considered forbs or herbs.
- Calla lilies contain two poisonous ingredients: oxalic acid and asparagine protein. The roots of the plant contain the most toxic chemicals. If a human or animal ingests portions of a calla lily plant, expect eye and oral swelling, burning, redness and pain. As an oxalate plant, swelling may cause airway blockage, although rare. Nausea, vomiting and diarrhea may follow. If symptoms of poisoning occur, contact a veterinarian or health care provider immediately. Wipe the affected mouth with a cold, wet cloth to remove as much plant debris as possible, according to Medline Plus.
- Since calla lilies bloom from late spring to early summer, warm-weather brides often select the blooms for their wedding day. With smooth, green stalks measuring 12 to 24 inches in length, calla lilies bundle easily for bouquets and centerpieces. The elegant flat-back, tulip-like shape of the calla lily bloom lies smooth against clothing, making it a preferred flower choice for corsages and boutonnieres.
- Although calla lilies grow in a variety of colors, the white bloom dominates the floral industry. The neutral-colored choice coordinates well with red roses -- or any colorful round, full blooms. Chrysanthemums, zinnias, sunflowers and carnations add texture and shape to a bouquet of calla lilies. For visual appeal, avoid mixing calla lilies with flowers having a similar sized bell-shaped bloom, such as tulips. However, stems of flowers with multiple tiny bell-like blooms, such a lily of the valley or bluebells, complement the shape of the calla lily.
