Arbor Day Celebration and Pop-up Plant Clinic at Daley Plaza

On Arbor Day, April 29, 2016, the Arboretum was once again downtown Chicago, this time in Daley Plaza for its second Arbor Day Pop-Up Celebration. More than 2,300 people joined us on that day to vote for their favorite trees. In the end, the magnolia tree took the top spot, but was followed closely by the oak and other species. Visitors to our pop-up also had the opportunity to talk with Arboretum experts and staff. Our Plant Clinic answered a wide range of tree and plant questions and handed out helpful materials.  Thank you to all who joined in this fun Arbor Day event.
