Succulents are still popular for bridal bouquets and boutonnieres, and I love them. What is kind of neat about using succulents in your wedding is that after the wedding you can carefully remove the succulent from the boutonniere or bouquet and shove it in some soil. It will take root after a couple weeks and you will have a living keepsake from your wedding day!
Top boutonniere - succulent, anemone, clematis buds
Bottom boutonniere - hellebore and sword fern
