Thank you for visiting Portland Japanese Garden’s Iris Tracker! As summer approaches, the Garden uses this space to keep its community up-to-date on the status of the irises that bloom next to our Zig-Zag Bridge and koi. Now, at the beginning of June, we’re seeing many buds begin to swell among the leaves — soon we’ll start to see glimpses of purple emerging throughout the green.

We want to remind you that the best way to experience our irises is by becoming a member of Portland Japanese Garden, so you can enjoy exclusive hours Wednesday through Monday, when the grounds are quieter and are easier to photograph.

Irises at Portland Japanese Garden

Native to Japan, Iris ensata is commonly known as “Japanese iris” outside of Japan. In Japan, 花菖蒲 (hanashobu) have been cultivated for over 500 years. Oregon and Washington are home to three of the nine specialty nurseries specializing in Japanese irises in the United States. Spuria, according to the American Iris Society’s encyclopedia, “are tall (2 to 5 feet in height) and elegant, and have very attractive foliage.”

As Portland Japanese Garden transforms into a picturesque and verdant haven, the irises provide a pop of color as the harbinger of summer. The buds typically open in late June to reveal flowers nearly six inches across in shades of purple and white. Symbolizing purity and innocence, the narrow iris leaf resembles the shape of a samurai sword blade.
