This week-long loop carries you from Portland’s elegant gardens to the Swan Island Dahlia Festival in Canby, through orchard country in Hood River, and up to Seattle’s serene arboretums.

Behind The Garden Wall - The Portland Japanese Garden

The Portland Japanese Garden, set in the hills overlooking the city, provides a peaceful refuge for those seeking rest in an atmosphere of tranquility.  Follow me to see what grows behind the garden wall.

To heal the wounds of war.

After the horrors of World War II, a number of Japanese gardens were planned in the United States as a way to heal the wounds of war, provide citizens with beautiful gardens, and promote cultural understanding. Portland Japanese Garden was one of those. Planning began about twelve years after the end of the Pacific War. It was hoped that “needing no translation, an American could experience firsthand Japanese ideals and values, communicated simply through nature.” Perhaps the irony was not lost on Allied veterans.

The idea was conceived by Mayor Terry Schrunk and other citizens of Portland. The chosen site was the original Washington Park Zoo. A few remnants of the old zoo remain. For example, the present-day koi pond was formerly the zoo’s original bear pit. In fact, the zoo began as a bear pit where unwanted bears were captured in the interest of public safety, and penned for public amusement. (Mayor Schrunk, once accused of perjury related to labor-racketeering, managed to avoid being penned.)

According to the garden’s literature, “The site was dedicated in 1961, and Professor Takuma Tono of Tokyo Agricultural University was retained to design the Garden. Professor Tono’s plan included five different garden styles laid out on 5.5 acres. This was quite a departure from gardens in Japan which typically follow one singular style. His intention was to represent different historical developments in Japanese garden architecture and through that communicate Japanese culture to create a cultural exchange.” Professor Tono was one of the most revered landscape architects of his time in Japan.

The garden was finally opened to the public in 1967, though some portions were not completed until May 18, 1980. The completion was celebrated with some fanfare, but Mount St. Helens overshadowed the event with a big bang of its own.

A great deal has been written about Portland’s Japanese Garden, so there’s no point in reiterating much, but to say that the garden now consists of eight different Japanese garden styles on 12 acres. Some are pictured below.

I must remark that the staff people were very pleasant, and the docent who guided our tour was exceptionally knowledgeable and agreeable. She was, of course, an avid gardener with a great deal of personal experience to draw upon.

Here are some of my photographs, with a few comments. Click on the images to enlarge them.

Trees such as this Japanese Maple (Acer palmatum) are carefully pruned to create negative space. Negative space becomes as much a feature of interest as the tree itself.

The Sand and Stone Garden, seen from above. Zen gardens make use of sand, gravel and larger rocks to recreate natural scenes. Swirling patterns in sand suggest motion of water. Larger rocks suggest islands and mountains.

This lovely vista from the Strolling Pond Garden is probably one of the most photographed in the garden. When the docent said so, everyone snapped a picture, which further established its status.

May is an ideal time to visit the Portland Japanese Garden when azaleas and rhododendrons are in bloom.

If planning to visit Oregon, the Portland Japanese Garden should be included in your itinerary. For visitors and residents of the city, the garden affords a unique opportunity to escape the insanity below.
