Hillsboro parks are home to hundreds of trees. How many of them can you identify? Whether the answer is none or every single one, you can discover our trees in a whole new way by visiting a Hillsboro Pop-Up Arboretum. 

During the month of April, temporary arboretums will be "popping up" in Century Oaks and Jackson Bottom Uplands:
