August, and with good reason, is Jim Gibbs’ favorite month for summer color at the Gardens. Undaunted by the heat, lush annuals and perennials spill over containers and weave together in planting beds, providing a continuous riot of color. It’s almost as if they have been waiting for just the right moment to take center stage. There are combinations that shine for sun and shade.
Summer blooming trees and shrubs like rose-of-Sharon, crape myrtles and roses of various colors are top performers during our Summer Colorfest.
The ponds bloom with over 140 varieties of waterlilies. Both hardy and tropical selections, these exotic flowers glisten like jewels.
A real show stopper is Hydrangea paniculata ‘Vanilla Strawberry’. The large blooms start out creamy white and turn pink, strawberry red and even burgundy, with cooler night temperatures. Like other PeeGee hydrangeas, this selection thrives in full sun.
