About This District

Originally designed as an arresting backdrop for the Main Fountain Garden, the Chimes Tower District is now a series of standout gardens and water features that warrant more than just a passing glance. The Hillside Garden features an enviable roster of rare and unique plants, thriving harmoniously throughout the sun-dappled slopes. At the crest of the hill, Oak and Conifer Knoll boasts an array of celebrated tree specimens, with some planted during founder Pierre S. du Pont’s time. The Eye of Water, Pear-Shaped Basin, and Waterfall—all originally part of the gravity-fed pump and reservoir system that once serviced the Main Fountain Garden—are three unique, and interconnected destinations for your exploration.

    Aromatic Aster

    Symphyotrichum oblongifolium ′October Skies′

    Symphyotrichum oblongifolium ‘October Skies’ is a compact, aromatic aster cultivar prized for its vibrant fall display. Forming neat mounds about 18–24 inches tall and wide, it features narrow, blue-green leaves with a pleasant fragrance when crushed. From September through October, it bursts into bloom with masses of daisy-like flowers in soft sky-blue to violet-blue, each with a bright yellow center. This low-maintenance perennial thrives in full sun and well-drained soils, tolerating drought and poor conditions, and adds reliable color to autumn gardens. These native perennials come in a variety of sizes and colors, and are one of the last major food sources for bees and other pollinators before the advent of winter. On a side note, asters, means stars in Latin, referring to the spectacular display of blooms at the end of summer!

    Heptacodium

    Heptacodium miconioides

    Seven-son flower is a deciduous, large shrub or small tree native to China, where it was first documented in the early 20th century and later introduced to Western horticulture. It is the sole species in the genus Heptacodium and belongs to the honeysuckle family (Caprifoliaceae). This plant is highly valued for its multi-season ornamental appeal. In late summer to early fall, it produces clusters of fragrant, creamy-white flowers arranged in groups that often appear to consist of seven buds, hence the common name. After flowering, the sepals turn a vivid red to deep pink, extending the visual interest into autumn. The plant also features exfoliating, light brown bark that provides attractive winter texture. Though once considered rare and even endangered in the wild, it has become increasingly popular in gardens and public landscapes due to its resilience, pollinator-friendly blooms, and year-round appeal. Heptacodium miconioides is an excellent choice for gardeners seeking a low-maintenance, high-impact specimen plant.
