Located on idyllic Pearl Harbor on Alaska’s Inside Passage, the Jensen-Olson Arboretum is a gift to the City and Borough of Juneau from Caroline Jensen, a long-time resident and Master Gardener. The Arboretum houses the American Public Gardens Associations Plant Collections Networks nationally-accredited collection for the genus Primula. One of Caroline’s passions, Primula are also known by their common name of primrose. The beds explode with their varied colors in early spring through late summer. Some of the species seen here are rarely grown anywhere else in North America.

“The vision of the Arboretum is to provide the people of Juneau a place that both teaches and inspires learning in horticulture, natural sciences and landscaping – to preserve the beauty of the landscape for pure aesthetic enjoyment – to maintain the historical and cultural context of the place and its people.” — Caroline Jensen

The Jensen-Olson Arboretum is located 23 miles north of downtown Juneau in the area known locally as “Out the Road.”  Watch for the square green mile markers on the shoulder of Glacier Highway. You will pass the Shrine of St. Therese just past Mile 22.  Continue seven-tenths of a mile and look for the Arboretum signs.  The Arboretum will be on the left.  Free parking is available.
