The University of Georgia's "Classic City Awards" program helps gardeners select from the best of the best. In this program, over 2000 plants are rated throughout the summer. Every two weeks an evaluator rates the plants using a scale of 1 (nearly dead) to 5 (exceptional). At the end of summer, these scores are averaged. Evaluations are based on number of flowers, the uniformity and habit of the flowers, leaf color, insect and disease resistance, and overall appearance. The "Classic City Award" winners are the ones that perform best in the UGA trial garden throughout the summer season.

From these trials, the highest performers are sent to retail outlets across the country for distribution to the public. Consequently, UGA is one of the professional entities upon which we gardeners depend. According to UGA, this award is the Oscar and the Tony of the plant world, so gardeners throughout the South and in many other parts of the country can have confidence that the Classic City Award winners will perform well in their gardens.

Here are six of the Classic City Award winners for 2011. Included are the scientific name, the cultivar name, the score, the common name, cultural requirements, and tolerances. The other ten winners will be discussed in a future article. As you study your catalogs this winter, plan your gardens for next summer and visit nurseries this spring, keep this list of high-performing plants handy.

This is not the only program of the University of Georgia that helps gardeners choose great plants for their gardens. In UGA's "Athens Select" program, outstanding plant varieties are chosen and distributed to retail outlets across the country for sale to gardeners just like us. Some members of this group are in the Southern Living Garden Collection that was begun in 2008 to introduce gardeners to worthy new plants. With help like this, selecting plants for our gardens is no longer the hit-and-miss proposition it once was. Listening to experts like UGA can save us money and increase our chances of selecting plants that will excel in our gardens.
