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.
