I always get asked by brides if I only work with succulents because of the name of my business.  While I love succulents, I wouldn't be a great floral designer if I only worked with one flower/plant.  I did have one bride who only wanted succulents with minimal flowers in her bouquet.  She wanted something sustainable that she could keep after her big day.  Sure enough, after her wedding she sent me a picture of the succulents in bouquet that were not neatly and beautifully placed in a terrarium.  Love me a good succulent bouquet!
