The average cost of flowers for your wedding mostly depends on the scale of the wedding you want to have. If it is just you and your close ones you will probably only need a bridal and a bridesmaid bouquet, maybe some reception flowers. This probably won’t cost you more than a couple of hundred bucks. However, if you want to go all big and traditional, be prepared to spend a lot of money on flowers. Experts say that people usually spend 10% of their wedding budget on flowers. For most of the couples, this is the amount between $6,000 and $11,000. However, there is no limit to how high up your budget can go.
