Freesia is one of the most fragrant flowers known to man. Native to South Africa, it's named for Friedrich Freese, a German botanist and physician. They're relatively easy to care for, and will last between five and 10 days, sometimes longer depending on the variety.
Fill a vase about halfway with cool water and add the accompanying flower food. Use a sharp knife or pair of scissors to diagonally cut about an inch off the stems. Remove any foliage that reaches beneath the water line. Leaves and flowers trapped under water can rot and cause bacteria to grow, which will harm your bouquet. To keep your arrangement looking its best, cut the stems and change the water about every two or three days. If you notice the water start to discolor, clean the vase immediately. Once you run out of floral food, you can use 1 teaspoon of sugar and two drops of bleach mixed in a gallon of water; this mixture will provide your flowers with important nutrients. If they begin to wilt, remove the drooping blooms.
Like a number of other flowers, freesias are sensitive to ethylene gas which causes them to deteriorate; they should be kept away from ripening produce as well as wilting plants. Place your bouquet in a comfortable area without cool drafts, heating vents or direct sun.
Freesias serve as a symbol of faithfulness and trust, which is why they're used to celebrate the seventh wedding anniversary. It's a popular wedding bloom, signaling the purity of the bride and the trusted bond between the couple. The freesia also symbolizes positive energy, making it a great gift for someone who's been feeling down lately. Freesias represent thoughtfulness, friendship and trust, and are appropriate bouquets for friends and colleagues.
