You can't go wrong with flowers. On Valentine's Day, it's the gift everyone really wants. But let's not kid ourselves. For some women, Valentine's Day is an annual contest of who will receive the best flowers. Cubicle-dwellers and others wait for their bouquets to be delivered around the holiday so they can compare vibrant colors and creative arrangements. The largest and most dazzling are declared the winners.

To ensure your gift comes out on top, avoid supermarket flowers or any other limp, unimaginative bouquets. Order a special arrangement with a diversity of colors and flowers online early to make sure your gift is delivered on time. Look for vibrant green foliage and feminine arrangements. Consider the size and color of the vase. Save money by choosing seasonal flowers or flowers in colors other than red, which tend to be more expensive around Valentine's Day. Consider the recipient's personality. Is she lively and stylish? Then her bouquet should be, too.

To preserve flowers for as long as possible, always re-cut stems at an angle before putting them into water. Change the water every few days, always giving the stems a fresh cut at the ends. Keep the bouquet away from direct heat, including sunlight.
