Choosing or asking for the right kind of cut flowers is not always as simple as it seems. While most flowers look good when you buy them, you’ll get more bang for your buck if they last a long time, sometimes three or more weeks. After asking for and buying your cut flowers, recut the stems at a 45-degree angle and arrange your flowers as soon as possible to ensure an even longer lasting display of flowers.
Decide what kind of flowers to ask for. Some flowers, such as carnations and gladiolas, last longer than other flowers like irises. Other flowers, such as roses, hyacinth and lavender, are more fragrant. If you're interested in bold, vibrant colors, flowers such as gerbera daisies and cosmos may be the best choice for you.
Request flowers with open and closed buds, especially when buying perennials and flowers that bloom in clusters. Or, choose a mixture of different types of flowers, some with open buds and some without. Then, enjoy the longer display of flowers as the closed buds open up after the original flowers fade.
Ask for at least two floral preservative packets with your flowers. Add one when you first arrange your flowers. Then, when the water goes sour, wash the vase, change the water and add the other preservative packet.
Buy potted flowers, such as orchids, instead of cut flowers. If you want to transplant them to the garden, ask for flowers that are hardy in your USDA Plant Hardiness Zone and require the amount of sunlight that your landscape provides.
