Since opening in 2004, Cornerstone's Gardens has drawn international acclaim from publications such as The New York Times, The Wall Street Journal, and Garden Design magazine. Newsweek states, "Cornerstone showcases the best in cutting-edge international landscape design," and the site is featured in "1001 Gardens to See Before you Die" as well as being named one of Sunset magazine's Top 10 Western Gardens for 2009.
