Colorado State University’s Flower Trial Gardens were established to evaluate the performance of flower cultivars in the unique environmental conditions of the Rocky Mountain region. The gardens consists of more than 1,000 varieties of annual plants and 300+ perennial varieties. Each year these plants are evaluated by industry personnel based on vigor, uniformity, floriferousness and tolerance to the environmental conditions. The results of this research are available to people throughout the state and can help with selection of the best plants for use in Colorado.  Learn more at http://flowertrials.colostate.edu.
