Sonoma County’s Oldest Butterfly Garden

Maintaining local wildlife habitat is one of the best ways we can support our community.

Welcome to Hallberg Butterfly Gardens

Nestled among the apple orchards of Western Sonoma County, our Gardens cover nine acres of overgrown vines, thickets, flowering pathways, and meadows.

We are a wildlife sanctuary and demonstration garden with a focus on Lepidoptera (moths & butterflies) and other pollinators (bees, beetles, wasps, flies). Hallberg Butterfly Gardens is a nonprofit 501(c)(3) organization.

Why Support Butterflies?

Butterflies and moths are insects belonging to a scientific group named Lepidoptera. Understanding butterflies can help us support our local wildlife because Lepidoptera provide critical functions within their ecosystem. Habitat loss greatly threatens native butterfly species and many other animals. To date, more than 54 varieties of butterflies are listed in Hallberg Butterfly Gardens observation records. Please visit our Butterfly Information page to learn more about the butterfly life cycle and their activity in the Gardens.

Garden Services.

The Gardens are open to the public by appointment from April to October (garden workdays continue year-round). We support environmental awareness by offering tours, events, plant sales, workshops, garden workdays, and educational resources! Our hours of operation vary depending on the type of appointment.
