I had no idea about this hummingbird garden in New Jersey. Thanks to onlyinyourstate.com, the only breed of hummingbird in New Jersey is the ruby-throated hummingbird. Perth Amboy is where the hummingbird garden is located. New Jersey Never Stops Surprising MeThis magnificent hummingbird garden is located at the intersections of High Street and Sadowski Parkway. I never knew about this fantastic little spot with the hummingbird garden and a butterfly garden so close.
