Front Range Tree Recommendation List ©

The Front Range Tree Recommendation List was developed through the collaborative efforts of 12 individuals, three from each of the four participating professional groups: the American Society of Landscape Architects (ASLA), the Colorado Nursery & Greenhouse Association (CNGA), municipal arborists representing the Colorado Tree Coalition (CTC), and the Colorado State University (CSU) Extension. Based on the committee’s collective education, knowledge, and experience more than 250 trees or varieties were evaluated and rated, resulting in a single reference list for professionals to use and share with their customers or residents.

Colorado State University Trial Gardens Top Performers

Each year the CSU Trial Gardens are used to evaluate the performance of annuals and herbaceous perennial plant species and cultivars under the demanding climate of the Rocky Mountain region. Growing conditions are characterized by high altitude, intense solar radiation, drying winds, severe hailstorms, large fluctuations between day and night temperatures, and a season-long need for irrigation. Plants are evaluated for plant vigor, uniformity, floriferousness, and tolerance to environmental and biotic stresses. Top performers are selected by a committee and published annually.
