Floral Design or floral arts is the art of creating flower arrangements in vases, bowls, baskets or other containers, or making bouquets and compositions from cut flowers, foliages, herbs, ornamental grasses and other botanical materials. Often the terms "floral design" and "floristry" are considered synonymous. Florists are people who work with flowers and plants, generally at the retail level. The term is not to be confused with floristics (the study of distribution and relationships of plant species over geographic areas.). Floristry is also not to be confused with horticulture which more broadly relates to the cultivation of flowers and plants.
