During July and August, over 500 crape myrtle trees bloom throughout Gibbs Gardens. Near the entrance of the gardens, looking down into the valley, are 100 white 'Natchez' crape myrtle trees sweeping the eye to a view of the North Georgia mountains. Another 40 'Natchez' crape myrtle trees with peeling cinnamon colored bark form a serpentine walk from the Grandchildren's Sculpture Garden to the Japanese Garden. Above the Rose Gardens an allée of 100 'Natchez' crape myrtle trees descend a gentle slope to a level viewing area, then ascend a gentle slope to the Daylily Garden. The Daylily Garden has an allee of 70 red Crape Myrtle trees providing shade for viewing.

More crape myrtle trees, in several shades of pink, mauve, lavender, and red, are sprinkled throughout the landscape.
