Bill Swineford, owner of Swineford Florist, said brides should count on having one or two flower arrangements in the church and more at the reception depending on the size of the wedding. One way to cut down on costs is to use the flowers from the church at the reception. This could be a wedding consultant or one of the ushers. It doesn't really matter, just be sure to designate someone in advance. The groom pays for the bridal bouquet, but the bride will want to make sure that her bridesmaids have bouquets, the groomsmen have corsages and that the parents, grandparents and reader have flowers as well.
Silk flowers is another option.
In addition to being affordable, a silk bouquet can be made for the bride to have in her portrait as well as on her wedding day. She can also hand down her bouquet as an heirloom like her wedding gown, and she doesn't have to worry about paying a premium for flowers that are not in season. Silk isn't as fragile either. If you're going to trade with one of the larger commercial florists you might want to be sure you're talking to the person who will actually have their hands on your wedding. That way you'll know your ideas are getting through and your tastes are compatible.
