About
What was once a farm and nursery for the Idaho State Penitentiary is now the Idaho Botanical Garden.
The 15-acre area reflects nature's beauty and operates as a nonprofit organization, emphasizing its commitment to environmental stewardship and community engagement. Unlike many botanical gardens, Idaho Botanical Garden is entirely self-funded, reliant on donations, grants, and the support of its visitors.
After the prison's closure, the land remained untouched for over a decade. It wasn't until 1984 that the Idaho Botanical Garden bloomed into existence. Crafted from the vision of local botanist Dr. Christopher Davidson and a dedicated board of directors, it transformed from a dormant land into a flourishing sanctuary.
Open from 9:00 am to 5:00 pm, the Idaho Botanical Garden invites visitors to immerse themselves in this lush oasis. Whether a tranquil stroll through the diverse plant ecosystems or participating in one of the many educational programs, the Idaho Botanical Garden offers a unique and enriching experience for all who visit.
Fun Facts & Cool Features
A standout feature of Idaho Botanical Garden is the enchanting English Garden, which opened in 1998. Designed by the famous English landscape architect John Brookes, this haven harmoniously blends over 1,300 perennial plants against the historical backdrop of the Old Idaho State Penitentiary's wall. It's a highlight to any Garden Valley getaway.
The Summer House was built from Table Rock sandstone with a black slate roof salvaged from the Veterans Home and a ceiling crafted from Boise's former J.C. Penneys store. The Summer House houses a magnificent wrought iron and copper weathervane made by local master blacksmith Nahum Hersom. This garden also honors Princess Diana with the dedicated Princess Diana Fountain.
Another intriguing aspect is the Children's Adventure Garden. This dynamic space ignites the imagination of young visitors, featuring play structures made from large hollow logs and other natural materials. It includes a carnivorous plant display, a treehouse overlooking the koi pond and Meditation Garden, and a unique musical trail.
Idaho Botanical Garden also hosts educational programs, encouraging hands-on learning and exploration.
