Longwood garden in PA,USA is 2 - 3 hours away from New York city. It is a beautiful flower garden. It has indoor, outdoor flowers, lake, tree, fountain show, outdoor concert, and fireworks. Beautiful and clean, very big, I toured 5 hours only toured 3/4 of it.
Nice place to visit and take picture all year round. Size of the garden maybe 20 - 30 football field size.
