Just like fruit, vegetables make for amazing arrangement alternatives to flowers because of their color, shape and texture. Try a mix of cauliflower, artichokes, mushrooms and rosemary sprigs. To arrange them expertly, first add a floral foam brick inside of the vessel after soaking it in water. Then secure each vegetable in place by pressing it to the floral brick. Once they’re in place, fill the gaps between them with rosemary sprigs.
