Time Out says
America’s oldest living botanical garden is a 45-acre landmark that offers visitors the opportunity to browse a selection of native plants, pore through the archives in the library, or take a luxurious walk through the eight-acre garden. While there is an opportunity to purchase guided tour tickets, admission to the grounds is always free of charge.
