Calla lilies come in several warm shades, perfect for a fall wedding or a rich color to use in summer or winter. You can choose from a palette of colors including shades of peach, orange, coral, burnt orange and rust. Pale watercolors of yellow to peach, or deep hues from orange to rust.
Finding items to coordinate with your orange calla lily theme is a bit more challenging. Many generic favors and decorations can be dressed up with mini orange calla lilies or simply pick up the color scheme to tie together your reception. Orange and peach are available in tulle favor kits, which are both easy to assemble. This link offers a (white) calla lily tie on and various colors of tulle. Or, accent your tables with your calla lily color using a richly colored favor box. Adorn it with a color coordinating ribbon.
Bouquets and centerpieces are dramatically simple with calla lilies alone. Orange calla lilies also work beautifully with other flowers like roses. For dramatic contrast, consider pale green hydrangea or yellow lilies. For a rich fall look, combine with deep reds.
