University of Illinois Extension connects people and their local horticulture and environmental concerns with the tools they need to pursue meaningful change. Whether it’s landscape aesthetics, sustainable practices, food production, pollinators, or a myriad of other topics, Illinois Extension has the resources people need.

Our unit is served by Martha Smith horticulture educator. She shares her 28 years of experience through a wide range of horticulture education, programs, training and research to benefit the environmental health and sustainability of our state’s ecosystems.

Martha shares information on some of her favorite plants, trees, flowers, perennials and more in her video series "Martha's Shed Talks" which you can view on our unit's You Tube Channel which you can view at

She is part of the Illinois Extension state horticulture team which also produces gardening websites, seasonal webinars and a YouTube channel to make horticultural information easily accessible to everyone.


From educational curriculum units to websites devoted to deeply exploring a single topic area, our resource collection represents best practices based on both proven and emerging research and the work of our professional education staff.

Green Screens, Fences, and Borders | May 11

The home landscape can be thought of as an extension of our living space and much like the rooms in our homes we can use plants as structural elements in the landscape. If you’ve visited an arboretum or botanical garden you’ve likely seen walls created with different plant species such as evergreens and perennial shrubs. Explore these design elements, some good species for creating screening, and design considerations for creating a green fence or screen successfully.
