Pollinator Garden Leavenworth Fish Hatchery
A showcase for gardening techniques
Experience sustainable gardening firsthand in this outdoor classroom garden. Learn about attracting pollinators in our engaging classes.
More Information
The Pollinator Garden at the Leavenworth Fish Hatchery was established in 2016 to create a safe pollinator and monarch butterfly habitat for educating students and the public. All the plants within the garden were chosen to provide nectar to pollinators, including over 200 milkweed plants and numerous plants native to Washington state.
Our Chelan-Douglas County Master Gardener Program has a partnership with the fish hatchery to help maintain the garden and interpretation. You can usually find Master Gardeners working here Tuesday mornings during the gardening season. Stop by to talk to them about pollinators and the plants that attract them, such as those listed below. Visit the garden in front of the main hatchery building at 12790 Fish Hatchery Road in Leavenworth, WA.
