Most gardens have a focus in the types of plants they grow. Examples include: native plants, natural forests, cultivated or wild gardens, woodland gardens, wetlands, and English or Asian gardens, to name a few. Others may offer several different types of these and other gardens within their landscape.

About Garden Tours
Many of the gardens in the following lists encourage free self-guided tours by providing signs, maps, and guides that you can download from their website or pickup at the visitor center or kiosk when you arrive.
Some of these Puget Sound gardens also offer docent-led guided tours. (A docent is someone trained to be a guide. Most, if not all docents at these gardens are volunteers who simply love gardens and want to share knowledge with others.) Some guided tours are free, but donations are gladly accepted.
All gardens appreciate donations to help defray costs.
Following the list of gardens in Seattle, Tacoma, and other cities throughout the Puget Sound region, you’ll find an event calendar of upcoming docent-led tours.
