Established in 1984 on the vacant land of the Old Idaho State Penitentiary, Idaho Botanical Garden is set on the Boise Foothills' base. It was founded initially as a tree nursery but soon became a non-profit botanical paradise. Spread across 50 acres (20.23 hectares), it includes 14 themed gardens and features more than 800 species of indigenous and non-native plants. It is the oldest of its kind in the state and a must visit if you love gardens. Stroll through their various sections like the Water Conservation Landscape, Children’s Adventure Garden, Summer Succulent Garden, Outlaw Field and Labyrinth, Jane Falk Oppenheimer Heirloom Rose Garden and Muriel and Diana Kirk English Garden. Enchanting and informative, the Idaho Botanical Garden is a great spot for a family outing or even with your special someone for a romantic date.
