Friends of Jensen-Olson Arboretum is a non-profit organization dedicated to supporting the projects and programs of the Jensen-Olson Arboretum, Southeast Alaska’s outstanding public garden and national primrose collection.

Caroline Jensen donated the historical arboretum property at 23-mile Glacier Highway to the City and Borough of Juneau. The Arboretum was opened to the public in 2007 and has evolved into a garden destination and a living laboratory featuring over  1200 native and cultivated species. 

The Arboretum embodies Caroline’s vision of a garden that inspires learning in horticulture, natural sciences, and landscaping while preserving its beauty for aesthetic enjoyment and maintaining the historical and cultural context. Caroline's garden is protected by a conservation easement held by the Southeast Alaska Land Trust so that her garden will remain for future generations to enjoy its beauty.

Caring for Caroline's Garden
Friends of Jensen-Olson Arboretum supports the projects and programs of the Arboretum through fundraising, public outreach, education, and organizing volunteer service at the Arboretum.

Fundraising activities include the annual sale of arboretum plants at the Super Plant Sale, the Saturday before Mothers Day. Sale of  Baseball caps with the arboretum logo and commemorative bricks are offered all year round (support page).

Special projects in 2018 were construction of an entry arch (thank you Bill Ehlers), a new parking lot, new access trail (thank you Trail Mix), and entry information panel. In 2019 we raised funds for the Lovely Loo, improved toilet facilities, which were given high priority in a survey of arboretum visitors. Our project focus in 2020 will be to improve interpretive signage.
