The Flowering Arboretum fills 17.5 acres in the center of the Botanical Garden. In 1982, a section of Crapemyrtle trees was added to the original acreage. Today the arboretum contains 336 different flowering trees. Because it displays a wide variety of fragrant and colorful flowering trees, homeowners and horticultural students look to the Arboretum as an excellent reference.
In 2015, the Flowering Arboretum will take on a new look that will benefit the environment and wildlife. Visitors will notice areas that are not mowed. As the grass grows mowed pathways will be created for increased visitation in the Arboretum. Visitors will expect to see wildflower meadows with increased activity for pollinators and wildlife.
