The Trial Gardens at the Dallas Arboretum were created for the purpose of expanding our research efforts and providing information to the public. The focus of the trial program is to grow and evaluate many different plants in the drastic climate of the Metroplex and North Central Texas. Information generated from the trials is provided to commercial plant producers, retailers, and home gardeners. Between 3,000 and 5,000 plants are trialed yearly from over 50 plant breeding companies. These gardens represent the cutting edge of horticultural research into heat-tolerant plants.
