Floristry is the production, commerce, and trade in flowers. It encompasses flower care and handling, floral design and arrangement, merchandising, production, display and flower delivery. Wholesale florists sell bulk flowers and related supplies to professionals in the trade. Retail florists offer fresh flowers and related products and services to consumers. The first flower shop in the United States opened prior to 1851. Floristry concerns the cultivation of flowers as well as their arrangement and sale. Much of the raw material supplied for the floristry trade comes from the cut flowers industry. Florist shops, along with online stores, are the main flower-only outlets, but supermarkets, garden supply stores, and filling stations also sell flowers.
