Gardens at Heather Farm, Botanical garden in Walnut Creek, United States.

The Gardens at Heather Farm is a 6.5-acre (2.6 ha) botanical garden in Walnut Creek, California, with a view of Mount Diablo. It holds more than twenty themed gardens, including the Native Plant Garden (1983), Cowden Rose Garden (1991) with its gazebo, and the Waterfall Garden (2000) with eleven waterfalls, ponds and two bridges.

In 1967 Walnut Creek park director Ruth Wallis met the presidents of three local garden clubs to propose a gardening association, which then asked the city for part of the planned Heather Farm Park. The Heather Farm Garden Center Association was incorporated in 1971; members Philip and Ruth Bancroft had donated land for the park. Groundbreaking took place on August 12, 1979, and the association's Garden Center building opened in 1983, paid for by plant sales, donations and grants.

The garden functions as a meeting place where visitors learn about sustainable growing and native plant conservation through hands-on programs. Local residents and community members gather here regularly to exchange gardening knowledge and develop their skills.

The gardens sit at 1540 Marchbanks Drive in Heather Farm Park, on the southeast slope of Mount Diablo, and are open every day of the week during daylight hours. Enter from the park side; the garden center building, opened in 1983, stands on the grounds. Plan a loop through the themed plots, which are planted for close viewing rather than long walks.

The site features specialized sections with water gardens, herb collections, and rock formations designed to attract butterflies and support other local wildlife. These nature-focused design elements create distinct habitats within a compact space.
