Rhododendrons and azaleas are spectacular flowering shrubs. Unfortunately, most rhododendrons and azaleas (there are over 900 species and innumerable varieties) cannot be successfully grown in Iowa because of a lack of cold hardiness. A small number, however, can tolerate our harsh winter weather. Selection of cold hardy varieties, correct placement in the landscape, and proper planting are the keys to successfully growing rhododendrons and azaleas in Iowa.
