Which crops are included in horticulture?

Horticulture is the branch of plant agriculture focused on the intensive cultivation of garden crops, which are generally categorized into food plants and ornamental plants.1

Food Crops

• Pomology: This field covers fruit and nut crops.1
• Olericulture: This involves herbaceous kitchen crops, including edible roots (e.g., carrots), stems (e.g., asparagus), leaves (e.g., lettuce), flower buds (e.g., cauliflower), fruits (e.g., tomatoes), and seeds (e.g., peas).1

Ornamental Crops

• Floriculture: This includes the production of cut flowers, pot plants, and greenery.1
• Landscape Horticulture: This broad category encompasses plants used for landscaping, such as lawn turf and nursery crops like shrubs, trees, and vines. The nursery industry also includes ornamental bulb crops—such as corms, tubers, rhizomes, and true bulbs—as well as certain perennial vegetables like rhubarb.12
