The Idaho Botanical Gardens received its first Board of Directors in 1984 through the efforts made by Botanist Christopher Davidson. The board hoped that through the development of an aesthetic landscape filled with educational gardens and elaborate plant collections, they could foster an appreciation of gardening, horticulture, botany, and conservation.

The Garden comprises a total of 33 acres, 15 of which are still under cultivation. It is located on land owned by the State of Idaho and was once a part of the Idaho State Penitentiary. The area is now known as Boise’s Old Penitentiary Historic District. The rolling foothills located behind the Gardens are used for hiking and environmental education.


Gardens: The Idaho Botanical Garden contains numerous specialty gardens each with unique focus and displays. There are also a variety of sculptures, art, and architecture scattered throughout the display gardens.

Water Conservation Landscape: This garden covers one acre of previously undeveloped and weed infested flat ground along Old Penitentiary Road. It now serves as a demonstration garden which features water conserving plants and helps control obnoxious weeds and unfriendly exotic plants. To top it all off, the plants are not only functional but attractive as well.

Vegetable Garden: This garden is seasonal as well as educational. It provides edible summer vegetables, annual flowers, and even the fall harvest pumpkin patch. Visitors can learn how to grow and maintain their own vegetable garden as well as eliminate waste and conserve natural resources.

Summer Succulent Garden: This garden is located on the old concrete foundation of the Old Penitentiary’s poultry barn. The garden is seasonal but differs every summer so visitors will always have new succulents and cacti to look forward to.

Outlaw Field & Labyrinth: During the 1930’s, an all inmate baseball team was formed at the old penitentiary called “The Outlaws”. This field is now used primarily for concerts and special events. The labyrinth was added in 2001 and is modeled after the labyrinth at the Chartres Cathedral in France.

Meditation Garden: This garden lives up to it name by providing visitors with shady paths along flowing waters and beautiful blooming flowers. Visitors can take a break from the hot summer sun in this cool (sometimes up to 20 degrees cooler than other gardens in the collection) garden. This garden also has an inviting canopy area for summer picnics.

It was built to commemorate the bicentennial of the Lewis & Clark Expedition between Great Falls, Montana and The Dalles, Oregon.
