Landscapes with Healing in Mind

Jean M. Larson, Program Manager of the Center for Therapeutic Horticulture at the University of Minnesota Landscape Arboretum
If you are a gardener, or a nature enthusiast at any level, you already know the healing power of plants. Anecdotal evidence, personal experience and common sense support the fact that being around natural environments helps most people feel better. But what does science tell us about the healing power of gardens and landscapes?

Many gardeners that wanted to purchase more seed of quick growing vegetables like lettuce and radishes last fall ended up being disappointed because many suppliers were sold out. The trend for a higher demand for especially vegetable seeds is likely to continue. Getting our seed orders in early and purchasing seeds locally early this year will help ensure we get what we want.
