Who can resist a beautiful Beaux-arts library building located where Daffodil Valley meets Tulip Tree Allée?
If you live in NYC (or plants are your life) you don't have to; visit the New York Botanical Garden. "One of the world's largest and most comprehensive botanical library in the world" is in New York and on line!
Beware, the quality, depth and breath of the collections' texts and images could blow your roots off.
