While visitors to the gardens may witness the wondrous metamorphosis of the butterfly, even more important may be their own transformation as they experience a new awareness of nature.

Louise Hallberg By sharing the knowledge of butterflies and providing for their habitat, we seek to promote and inspire the appreciation and conservation of the wonders of nature.

It is my fervent wish to enhance and preserve the Hallberg Butterfly Gardens so that future generations will always have the opportunity to behold the beauty of nature's wonderful miracle - the butterfly.
-Louise Hallberg, 1997

Oldest Garden
The beginnings of what maybe the oldest butterfly garden in the country can be traced to the 1920s when Della Hallberg, an avid gardener, planted a California native vine called Aristolochia californica. These plantings of the Dutchman's Pipe would provide an abundance of larval plant food for the beautiful black and teal Pipevine Swallowtail.

Fortunately, Della Hallberg also planted a love of nature in the hearts of her children. Her daughter Louise lived in the family home until her passing in 2017 and enhanced the original gardens to provide habitat and food for over 40 butterfly species.
