When you plant a tree, the hope is that it will remain healthy and strong for decades but the recommendations for what to plant often change faster than the trees themselves, sometimes creating frustration and even controversy. On this Horticulture Day, we talk with Jeff Iles, professor of horticulture at Iowa State University, about how recommended plant and tree lists are created and why they sometimes spark debate.
