Spring is in the air, and what better time than now to visit some of the most breathtaking botanical gardens in the United States? Proper botanic gardens, according to Botanic Gardens Conservation International, meet specific criteria distinct from those for public parks or pleasure gardens. Botanic gardens, by definition, must exhibit proper documentation of the living collections, have underlying scientific basis for research, and be open to the public for the purposes of display and education.

The BGCI has a database on more than 2,500 botanical gardens from around the world. North American is home to more than 350 of them. We’ve handpicked 11 botanical gardens from across the United States, from the Santa Barbara Botanical Garden from the California coast to the United States Botanical Garden in the east.
