A husband-and-wife team of amateur botanists started this garden that sits on Johnson Creek. The couple have discovered 11 new Northwest plant species. Over the years, they expanded the garden from five to nine sprawling acres. You can peruse the garden at your leisure or take the curator's tour. The manor house, built in the 1930s, now holds nature-study classes for kids. The wedding chapel seats 85 people and can be rented. There is no admission charge, but donations are accepted.
