Trees, shrubs, and perennials are also part of the garden, providing an attractive backdrop to the changing display of showy annuals, and extending the beauty of the garden through winter.

A living kaleidoscope of seasonal color begins with the earliest and brightest of spring bulbs coupled with their cool-season companions and ends in a spectacular October finale, with towers of mums enhancing the hot-season annual plants.

Named for its circular boundary, this garden features a central dancing fountain with two intimate secret gardens off to each side. A central promenade invites strolling and close-up views of the cutting-edge plant combinations.
