Highline Botanical Garden, Botanical garden in SeaTac, Washington.

Highline Botanical Garden covers 10.5 acres (4.2 ha) at 13735 24th Avenue South, next to the North SeaTac Community Center. Its core is Elda Behm's Paradise Garden, where a 120-foot stream with a waterfall ends in a 7,000-gallon pond edged with glacial erratic boulders dug out during site grading. Around it lie the Seike Japanese Garden, iris and daylily beds, and the Celebration Rose Garden with its fountain and steel arches.

The garden began as a private property owned by the Behm family that was relocated in 2000 by 200 volunteers to prevent it from being demolished for airport expansion. This remarkable rescue effort allowed the original garden concept to be preserved and made accessible to the public.

The Seike Japanese Garden was built in 1961 as a war memorial to a fallen son and designed by Shintaro Okada of Hiroshima. It was moved to the Highline site in 2006 at a cost of over $350,000, with its bridges, large stones and hand-candled pines relocated. The garden was re-dedicated in June 2006.

The garden sits at 13735 24th Avenue South, one mile north of Seattle-Tacoma International Airport and just south of the North SeaTac Community Center and SeaTac Senior Center. It is open daily from 7 a.m. until dusk, with no admission charge.

A specialized Sensory Garden area features rain gardens and vine tunnels where plants are selected specifically for their fragrance and texture. Visitors can engage their senses and experience an unusual garden interaction here.
