Green Glen has been family owned and operated for more than 35 years. We strive to provide our customers with everything they need to beautify their corner of the world. With five hundred acres of nursery stock, knowledgeable staff, and personalized service, Green Glen offers much more than "big-box" home improvement stores.
 We carry a huge selection of garden supplies including annuals, perennials, trees, shrubs, and hard goods at competitive prices. Green Glen stocks gardeners' favorites and new trends in plants and supplies.
 Don't see what you're looking for?
We're happy to locate and order what you need.
 Because Green Glen is a garden center, not a home improvement super store, the plants we bring you are of the highest quality and have been cared for by garden professionals. In fact, we grow many varieties of annuals and perennials in our on-site greenhouses and grow hundreds of varieties of trees and shrubs on our farms. Ninety percent of Green Glen plant materials have been locally grown and all are grown in the United States. We care about our plants as much as you do.
 Many Green Glen employees have more than 20 years of experience growing, maintaining, and installing plant materials - our service is unparalleled.
  Let us help select the best plants, trees, and shrubs for your conditions and provide important care information.
"Green Glen is a third-generation family-owned garden center and we're proud to continue a tradition of offering the best supplies and service in Illinois. Bring your gardening family to meet ours!"
