Calla lily wedding invitations are a popular form of a flower wedding invitation. It's rather ironic, however, that the calla lily itself is neither a lily nor an actual flower. The trumpet shaped blossom is actually made up of modified leaves and is recognized worldwide as a timeless symbol of purity, exuding an air of sophistication in every setting. The calla lily has long been a favorite of artists, connoisseurs and brides. You may recognize the image of a calla lily from its use in many paintings, specifically works of art from Diego Rivera, for example, The Flower Vendor. Calla lilies grow in warm tropical climates and while being somewhat expensive, they make an impressive visual, worthy of your respect. They are also noted for having a long vase life making them very popular for use in elegant, sophisticated wedding arrangements. The calla lily is widely cultivated for ornamentals and cut flowers. You will often find calla lilies used in bridal bouquets or table centerpieces at weddings. The flower is noticeable for its showy white, yellow, pink and purple spathes.
