Here is an idea keep a piece of your bouquet or boutonniere living on well beyond your wedding day. I love succulents for a bridal bouquet, wedding reception centerpieces and boutonnieres. Did you know you can take some of these succulents and re-pot them? It takes some work and not all will survive. It will also depend on the construction of the bouquet. I see many designers use hot glue on some succulents to keep it in there.
One of the many succulents from the groom's boutonniere transplanted and growing.
The designer used a lot of hot glue, so only one succulent from the bouquet survived. These can be cut and transplanted as it grows.
