Idaho Botanical Garden

2355 Old Penitentiary Rd, Boise, ID 83712 - United States





Located in Boise’s Old Penitentiary Historic District, the Idaho Botanical Garden is dedicated to enhancing our community’s quality of life through fostering a love of nature and developing intellectual curiosity in people of all ages. Originally the site of the tree nursery and grounds of the State Penitentiary, the Garden is a living museum.


The Idaho Botanical Garden is a special place in the Boise Community. The tranquil grounds are home to diverse plant collections, bubbling fountains, wildlife, quiet walkways, and distant vistas. The garden is also a unique outdoor gallery of art, and is honored to host multiple sculptures created by the late Dr. Max Kaslo CDR USNR.
