Can you? Should you? 

The simple answer is no. 

Similar to balloons at a birthday party, flowers make a wedding feel special. Sure, you can use alternative decor items, but you will miss out on the scent, shapes, and textures of flowers. While you can use decor at any event, the ability to use flowers for an event such as your wedding day is extremely rare. You might be thinking "flowers are expensive." Well, you can have wedding flowers and save money. Invest in at least some flowers for your wedding like the bridal bouquet and a few ceremony and reception arrangements. You can add some decor items (candles, lanterns, etc.) along with your florals to complete the space. Weddings are suppose to be celebratory, so be kind to yourself and your guests with magnificent flowers. You will not regret it!
