August 1, 2018
Summer is at its peak, and you will find many popular flowers in bloom now that would have been familiar to European and Asian settlers, such as daylilies, hostas, lilies, rose-of-Sharon and waterlilies. But it’s also the season for our native American species to shine. The yellow daisy flowers of compass plants in the prairie tower over wild bergamot, mountain mint, Culver’s root and nodding onions. Other native perennials that stand tall include sunflowers, Joe pye weed, big bluestem, compass plant and tall coreopsis. In garden displays look for “nativars”, cultivated selections of native wildflowers. 'Annabelle' and the newer Incrediball® types of hydrangeas are derived from the wild hydrangea of eastern North America. We have many nativars of purple coneflower, black-eyed Susans, rose mallow, phlox, sunflowers and obedient plant on display. Enjoy a colorful summer walk at the Chicago Botanic Garden.
