The Carl S. English, Jr., Botanical Garden (7 acres) are botanical gardens located on the grounds of the Hiram M. Chittenden Locks at 3015 NW 54th Street, Seattle, Washington. They are open daily 7 a.m. to 9 p.m. without charge.
After the locks were built in 1911, landscape architect Carl English of the United States Army Corps of Engineers transformed the construction site into garden in an English landscape style. All told, he spent 43 years planting and tending the gardens. Today they contain more than 500 species and 1,500 varieties of plants from around the World, including fan palms, oaks, Mexican pines, rhododendrons, and a fine display of roses.
