Botanic Garden: Prospect or Crown Heights?

Which neighborhood does Washington Ave. across from the Botanic, down from the Museum fall into? Prospect or Crown Heights?

I liken this to the Flatbush divide of Prospect Heights and Park Slope - west side is the end of Prospect Heights, East side is the beginning of Crown Heights.

North of Prospect Lefferts Gardens? (NoProLef?)

Subject: "Botanic Garden"

When I posted this topic I didn't realize there was a previous and extensive thread on the neighborhood naming thing.
Allow me to declare that part of Washington Ave adjacent to the Botanic (South of Eastern Parkway/Brooklyn Museum and North of Empire Boulevard) "Botanic Garden"

Crown Heights down to Empire.
