We grew our own wedding flowers for two reasons: 1) It was a hugely generous and sentimental gift from D's parents, who grew hundreds of Irises on their property for the wedding. 2) We had a $5,000 budget that could have easily been spent on flowers alone. In the end, we spent $100 on two small bouquets and three boutonnieres, using our home grown Irises for the rest.
In hindsight, I am always on the look out for flower and centerpiece alternatives. Not just for money-saving reasons, but also for the sheer creativity of shirking tradition and finding ways to uniquely express oneself.
