I went the brooklyn botanical garden 2 weeks ago. It was GORGEOUS! I've gone every year since I was a freshman at Pratt (it's free for us and our guests so I take full advantage of that!) The walk there alone is really diverse and at points can be quite gorgeous, even the peeled paint on the side of the building is quite nice just because of the character.
Here are some photos I took from the Garden:
(I love that they put the name of the plants)
