With spring atour doorstep, many of us may be thinking of doing some landscaping at home. Here is a tip from Penn College's Horticulture Club: Think about using native plants. This not only will give the landscape a natural feel, but it may be easier on your pocket and save you some time. Native plants that are already adapted to the local environment will require less care and fewer resources, and will thrive in your landscape while you relax and enjoy. The weekly Green Tip is a cooperative venture of the Energy Conservation Subcommittee (part of Penn College's Governance system) and the School of Natural Resources Management's Horticulture Department. Contacts for the feature are Gail B. Landers, group leader at the Children's Learning Center and a subcommittee member, and Carl J. Bower Jr., horticulture instructor.
