Tree Collection

Franklin Park Conservatory sits within an 88-acre green space oasis and is home to 1,593 trees, including 169 species, that provide important ecological benefits such as cleaner and cooler air, bird and pollinator habitats, beautification, and health improvement for neighbors. Urban tree canopies are critical to improving air and water quality, reducing greenhouse gasses and atmospheric warming, beautifying the community, and positively impacting the health and wellness of urban residents. The Conservatory’s horticulture team is committed to the health and maintenance of its current tree collection, not only for the benefit of our visitors but for the entire community living and working in downtown Columbus.

Old Man’s Beard, also known as the American Fringetree, is a native understory tree to shaded forests, organically rich woodlands, and flood plains of Eastern North America, including Ohio. The name, Old Man’s Beard, refers to the long tassels of white flowers that emerge in middle-to-late spring, end of April to mid  May. In Southern wild populations, a rare and unusual, reddish-pink flower may be seen.

 This tree has a wide tolerance of growing conditions from sun to shade. Old Man’s Beard is dioecious, separate male and female trees, and is prized for its wonderful flower display.  This tree can be a beautiful specimen plant in the landscape as both a fruitless male or as a fruiting female tree.  

As a native tree, there are many benefits to wildlife that Old Man’s Beard offers. They serve as a host plant for several species of butterflies and moths, specifically the Rusty Sphinx moth, and the attractive dark blue fruits on female trees feed a variety of wildlife, including Cedar Waxwings and other fruit-eating birds.
