One of the most readily available flowers out there is Alstroemeria. This species is a hit with homeowners because of its longevity; it can last up to 14 days in vessels and vases. It's important to keep Alstroemeria far away from produce since most fruits and vegetables emit ethylene, a gas which can considerably decreases the Alstroemeria's vase life.
Daffodils: Vibrant and Tricky
Although daffodils are one of the springiest, most vibrant flowers out there, they're also one of the trickiest to work with and shouldn't come into contact with any other species. When using cut daffodils in vases or vessels, it's important not to mix them with any other types of flowers. Daffodils release a stem-clogging sap which will cause other flowers to wilt.
Tulips: Whimsical and Elegant
While many species of cut flowers fare better in vases when floral food is added to their water, tulips are fine without it. Within one bunch, you may find certain tulip stems turning, twisting and bending up, down, left and right. To keep them from harming one another or wrapping around another stem too tightly, try to periodically adjust how the tulips are situated within a vase. By following these tips, cut tulips can last up to eight days.
Mums: A Little High-Maintenance
Mums, while easy to take care of once cut, drink a lot of water. Once you've got fresh-cut mums placed in a vase or a vessel, be sure to rigorously check the water line. While it's okay for many cut flowers to sit in a vase with a water line which sits near the halfway mark, it's best to keep those with mums filled almost to the top.
Pare Down Arrangements
Believe it or not, some of the most beautiful arrangements out there are simply pared-down versions of supermarket bouquets. In order to update a basic supermarket bouquet into something more designer-grade, remove filler such as baby's breath, and consider cutting down each flower's length dramatically. This will result in turning a lackluster bouquet into a neat arrangement.
Make Use of Fallen Flower Heads
Many times while rearranging supermarket bouquets, a flower head may break from its stem. Have no fear, it can still be put to good use. Consider floating the detached head inside of a small bowl. Multiples can be used to create a lively, graphic centerpiece, or the heads can be used singularly to add life to a windowsill or countertop.
