Late Summer Bloomers (Updated Aug. 22) -  There are some BIG standouts in the gardens at this time of year, such as the Dinner Plate Hibiscus which can be seen in the Slade Perennial Garden and the MacMillan Terrace Garden, both behind the Snyder Building. Late bloomers such as the prolific Flowering Spurge and Helium Autumnale (Autumn Sneezeweed) will go on until frost. Stalks with giant white blooms of the Plantain Lily can be found in the Hosta Glade. Waterlillies are a delightful sight in the Perennail Garden Fountain, and will continue to bloom as long as the water temperature is above 60 degrees. Showy varieties of Hydrangea can also be found throughout the grounds. The hop-on, hop-off Bee Line Shuttles (Thursday through Sunday, 11:30-4:30) make it easy to spend the day and see everything the Arboretum has to offer in the summertime.
