Depending on which flower delivery service you order from, the arrangement may come in a vase, box, or simply be wrapped in paper, plastic, or recyclable material. Vases vary in material, height, width, color, and opacity. If your order does not come with a vase, experts recommend finding a container that adequately supports the types of flowers in your bouquet. For instance, tulips tend to look their best in a straight-sided vase.
