Here is a favorite for many brides... the Mini Calla Lily Bouquet. They come in some amazing colors and two favorites are the dark, eggplant purple and the "orange" rust or mango (seen here) which can be a lighter yellow orange, or a darker redish orange.
Year round you can always get all white mini calla lilies.
Mini calla lilies are always going to be expensive. Growers say it's all about supply and demand. Brides love these flowers and growers can't grow enough of them.
Other colors they come in are a bright yellow, pinks and peaches, purples and lavendars.
A lot of times you may see that they come in red, but be cautious about a red mini calla lily. they are not the "classy" red of a rose, but more of a purple red.
One last thing I wanted to point out was the ivy and looped bear grass. Both of these are fun and different ways to add green to your bouquet and give it a little texture with out being overwhelming. this look is great in all rose, gerber daisy, or tulip bouquets as well.
