What's in Bloom
Set on twenty-five acres adjacent to Rock Creek Park, Hillwood’s Gardens contain a diverse and fascinating array of plants. Summer is a great time to enjoy the color in the cut flower garden!
Summer is here!
Hybrid Bigleaf Hydrangea (Hydrangea macrophylla) This is the classic hydrangea, with globe-shaped mophead flower in shades of blue or pink and huge, dark green serrated leaves. Great for the shade garden and in garden borders. Depending upon the cultivar, the size is usually three to six feet high and wide.
Hummingbird Summersweet (Clethra alnifolia ‘Hummingbird’)
Clethra is one of those great late summer plants you can’t miss because of its strong fragrance and pure white flower spikes. Summersweet comes in many cultivars, with white or pink flowers. ‘Hummingbird’ is just 2.5-3 feet tall and wide and spreads nicely with age.
‘Annabelle’ Smooth Hydrangea (Hydrangea arborescens ‘Annabelle’) One of the most popular hydrangeas, known for its pure white, massive, globe-shaped flower heads and its ability to light up a shady border. In recent years, growers have also developed cultivars with light pink blooms
Showy Jasmine (Jasminum floridum) is a mounding arching shrub producing clusters of deep yellow flowers that do not open all at once, instead they open over a much longer period providing color from spring through summer. It differs from some jasmine in that it has alternate leaves.
Oakleaf Hydrangea (Hydrangea quercifolia) This plant is distinctive for its large, oak-like leaves that turn a beautiful reddish-purple color in fall, and for the large, pyramidal-shaped pure white flower panicles that eventually fade to a rosy pink hue. With time, the exfoliating bark adds a spark of winter interest.
