I also went to the Seattle Japanese Garden and I will post about that separately. They are distinctly different gardens.
I won't go into too many historic details of the garden's history, but the garden was established by Fujitaro Kubota in 1927. (See www.kubotagarden.org for garden details.) He acquired the land and worked his entire life to clear it and establish this garden. He was 83 when the garden was completed.
Mid-May was the perfect time to see the garden, as the wisteria, rhododendrons and azaleas were blooming.
There isn't any signage on the plants, so I didn't get any names of plants.
