The Horticulture category focuses on businesses engaged in the cultivation of fruits, vegetables, flowers, turf grass, and ornamental plants. Generally production involves relatively small acreage and more intensive methods as compared to that of field crops, although this distinction is not always precise. Businesses in this sector may be described as:

• Nurseries, including trees, shrubs, exotics, perennials, bedding plants, and bulbs,
• Market Gardeners or Produce Growers,
• Greenhouses,
• Orchards,
• Christmas tree farms,
• Seed companies,
• Turf farms, or
• Floral companies.

Companies offering materials and supplies specifically designed for horticultural producers are also found here, as well as sites related to the import and export of horticultural products.

Industries included are those who typically supply wholesalers, retailers, landscapers, other growers, supermarkets, and occasionally home consumers.

Sites not listed in this category include:

• Sites providing information about home or hobby aspects of horticulture are listed under Home: Gardening.
• Industries involved primarily in the processing, packing, and delivery of produce to retailers or end users are listed under Business: Food and Related Products: Produce.
• Field Crops are found under Business: Agriculture and Forestry: Field Crops.
• Sites related to scientific, research and technical aspects are found under Science: Agriculture: Horticulture.
