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.
