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.

What’s in Bloom

  • Japanese Anemone

    Anemone × hybrida ′Honorine Jobert′
  • Rough Goldenrod

    Solidago rugosa ′Fireworks′

    Solidago rugosa is a native perennial that forms loose spreading clumps of arching, hairy stems. Growing from creeping rhizomes, the general height of this plant is six feet tall and grows in wet soils, open woodlands, thickets, old fields, bogs, and along roadsides. The conditions best for this plant are full sun with average well drained soil. The golden yellow flower heads are held in loose panicle-like arrays. Its adaptability and the fact that it is not as aggressive as other goldenrods make it a great native plant for perennial borders and gardens. 'Fireworks' was selected for its shorter growth habit and heavier flowering. When in bloom the open flowers resemble fireworks. This cultivar reaches only about three feet in height.

    Aromatic Aster

    Symphyotrichum oblongifolium ′October Skies′

    Symphyotrichum oblongifolium ‘October Skies’ brings clouds of lavender-blue, yellow-centered flowers to the autumn garden. This compact aromatic aster grows 18–24 inches tall, with leaves that release a fragrance when crushed. Its name is said to evoke the blue skies of October. Thriving in full sun and well-drained soil, it tolerates drought and provides late-season food for bees and butterflies. From the Meadow to the Idea Garden, explore the varied colors and forms of our native asters and their cultivars as they brighten the fall landscape.

    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.
