Making Your Own Flower

Flowers have long been used to symbolize life’s important events and emotions. Roses are symbols of love, lilies, the flowers of death and renewal, and carnations a sign of appreciation. We use flowers as wedding decorations, Valentine’s Day presents and Christmas ornaments. No matter what the occasion is, a beautiful flower arrangement is a wonderful way to celebrate life through vibrant colors and rich floral scents. Florists provide customers with a variety of arrangements made specifically for certain occasions and events. However, if you are on a budget, flower arrangements can be fairly pricey. Professional florists charge exorbitant amounts for their expertise, and the flowers themselves can be extremely expensive. Making your own arrangements can be a fun and creative alternative to ordering pieces from a florist. By purchasing flowers individually, you can choose the exact colors and scents you need to say exactly what you want to communicate. When making your own flower arrangement, you should first consider its purpose. If you are making arrangements for a wedding, white is typically the presiding color. You should start with basic white flowers and add a few accents that match the bridesmaids’ dresses. Large leafy green pieces add a nice contrast to delicate buds for table centerpieces, and sometimes simplicity is the best aesthetic tactic. If you are making centerpieces for several tables, you can purchase your flowers in bulk and use one design over and over again, or you can make each piece an individual work of art by: Sintilia Miecevole

Flower and pollination

Each flower has a specific design which best encourages the transfer of its pollen. Cleistogamous flowers are self pollinated, after which, they may or may not open. Many Viola and some Salvia species are known to have these types of flowers.Entomophilous flowers attract and use insects, bats, birds or other animals to transfer pollen from one flower to the next. Flowers commonly have glands called nectaris on their various parts that attract these animals. Some flowers have patterns, called nectar guides, that show pollinators where to look for nectar. Flowers also attract pollinators by scent and color. Still other flowers use mimicry to attract pollinators. Some species of orchids, for example, produce flowers resembling female bees in color, shape, and scent. Flowers are also specialized in shape and have an arrangement of the stamens that ensures that pollen grains are transferred to the bodies of the pollinator when it lands in search of its attractant (such as nectar, pollen, or a mate). In pursuing this attractant from many flowers of the same species, the pollinator transfers pollen to the stigmas—arranged with equally pointed precision—of all of the flowers it visits.Anemophilous flowers use the wind to move pollen from one flower to the next, examples include the grasses, Birch trees, Ragweed and Maples. They have no need to attract pollinators and therefore tend not to be "showy" flowers. Male and female reproductive organs are generally found in separate flowers, the male flowers having a number of long filaments terminating in exposed stamens, and the female flowers having long, feather-like stigmas. Whereas the pollen of entomophilous flowers tends to be large-grained, sticky, and rich in protein (another "reward" for pollinators), anemophilous flower pollen is usually small-grained, very light, and of little nutritional value to insects
