While in Seattle last month a bunch of us went to visit the Bloedel Reserve, a most lovely garden / woodland / meadow on Bainbridge Island. What a delight of scenes, reflections in the ponds, a japanese garden, moss garden, textures.
The owner and his wife resided there from 1951 to 1986 and developed this place. Among other things, the house has an extensive library of mostly bird and plant books.
I strongly recommend a visit there if you get a chance.
