I know! Brilliant! Why not a bouquet of leaves? Like flowers they are colorful and seasonal. Unlike most floral centerpieces available in the cooler months, they are FREE! I love free. Free is good. And just like my beloved gourds, they have an extended shelf life. I know! Why had I not thought of this earlier?
Mix different variety of leaves or collect ones in one color. Use a jar instead of a vase or tie the stems with ribbon and place small bouquets of them around the table. But most importantly, I suggest collecting leaves from branches that are within reach. Because, when it comes to putting leaves on your tabletop, you want pristine ones.
