I remember seeing the movie, 'You've Got Mail' and thinking, 'Wow, what a pretty garden! ...I wonder if they forced some of those plants to shoot this scene?' during the ending.
In case you too were momentarily distracted from the romantic tribulations of attractive, professional, and unimpeachably nice New Yorkers due to the cinematic horticulture, you may like to know this is the 91st Street Garden in Riverside Park.
As you can see, it's still a lovely garden, and I bet in May it looks just as colorful as it did in the film.
