Horticulture at Clackamas Community College

Love the idea of working outside in a growing, hands-on field? If you are looking for a career that combines art and science, as well as a balance between physical and intellectual work, CCC offers four areas of plant study that can get you out of the office and in contact with nature. CCC's horticulture department includes arboriculture, horticulture, landscape and organic farming programs.

For additional information, please contact Loretta Mills at 503-594-3292 or lorettam@clackamas.edu.
