Started by Bob and Denise Van Wingerden in 1985 with nothing more than one acre of greenhouse, CMG has continued to grow rapidly. Now with 15 acres of under-glass greenhouse and 15 acres of outdoor growing space, CMG went from solely supplying other greenhouses, to being a grower for Garden Centers, Landscapers, Grocery Stores, Big-box retailers, and anyone with a need of outstanding product.
