The original design was by the old landscape architecture firm of Hare and Hare. They proposed formal gardens in the central area and treating most of the site as a landscape. There is an Azalea Garden, a Hosta Glade and a number of gardens designed by well-known landscape architects. Koichi Kawana designed a Japanese Garden and there is work by John Simonds, Michael Van Valkenburgh and Jim Hagstrom. It is an enlightened policy for getting both quality and variety in the designed landscape.
