Jim and Jan Gulley began their dream of building a greenhouse business long before they opened their doors in 1975. Jan graduated from Colorado State University with a degree in horticulture. Jim grew up working at his father’s greenhouse in Denver. The Gulley’s began a small backyard business in 1975, growing Blue Spruce and Rocky Mountain Columbine. Five years later, in 1980, Jim and Jan opened the doors of their present location.

Gulley Greenhouse currently has 120,000 square feet of cold frames, 60,000 square feet of heated greenhouses, and another 17,500 square feet under construction for plug production. The greenhouses currently produce over 1,000 perennial, 200 herb and 650 annual varieties. Gulley Greenhouse produces 200,000 one-gallon size perennials, 15,000 three-gallon size roses, 800,000 2.5-inch perennials and herbs, three million plugs and 10,000 poinsettias at Christmas.
