Which area of horticulture produces the most jobs in the United States?

• A. Floral design industry
• B. Olericulture services industry
• C. Greenhouse and nursery industry
• D. Horticulture services industry

Answer: (C)

The size of employment comes from the scale and scope of plant production for landscapes, garden centers, and retail nurseries. The greenhouse and nursery sector covers growing and supplying ornamental plants, shrubs, and trees year-round, plus tasks like propagation, pruning, pest management, irrigation, and distribution. That broad, continuous demand across many regions creates a large, steady workforce, including seasonal labor, making it the area with the most jobs. Other sectors, such as floral design, olericulture (vegetable) services, or general horticulture services, are important but smaller in overall employment due to their narrower focus or seasonal patterns.
