Lilly gardeners and horticulturists is our Secretary germplasm, our li fe blood. I will devote the St. Paul, Minnesota next few commentaries to your concerns. I Mr. Gerald T. Halpin hope you take some time to respond. Treasurer Alexandria, Virginia We begin with the definition of horticul ture as an art and the need both to evaluate and to teach it as an art form. Webster traces "art" back to the Latin noun BOARD OF DIRECTORS "skill" and the Greek verb "fit" and defines art as "skill in performance Mrs. Suzanne Bales Bronxville, New York acquired by experience, study, or observation." Note its similarity to the Dr. Sherran Blair definition of science: "knowledge attained through study or practice." Columbus, Ohio Horticu'lture fares beautifully in Webster: "the science and art of growing Mrs. Mary Katherine Blount Montgomery, Alabama fruits, vegetables, flowers, and ornamental plants." Note the emphasis on Mr. William F. Brinton both art and science. The Society will focus its resources on these two areas Mount Vernon, Maine in the next three years. We will promote and develop professional and Mrs. Beverley White Dunn Birmingham, Alabama amateur education and wi ll concentrate in our publications, lectures, and Dr. John Alex Floyd Jr. symposia on the art, design, and philosophy of horticulture. Birmingham, Alabama Of the contemporary arts, sculpture is most like gardening. It is subjec Mrs. Julia Hobart tive and physically demanding. A great sculpture inspires and then moves Troy, Ohio Dr. Richard L. Lower the spirit; it is a wellspring of emotion and energy. A great garden performs Madison, Wisconsin the same function. The ultimate expression of the art of gardening is the Mr. Elvin McDonald Japanese garden. Several thousand years have resulted in the suggestion of Houston, Texas Mr. William G. Panni II a universe within a small space. Western gardens may be more expressive Martinsville, Virginia of a particular philosophy of life or of the power and mystery of the natural Mr. Lawrence V. Power world, but no western garden expresses so directly the relationship between New York, New York human nature and the greater universe as does a Japanese garden. We Dr. Julia Rappaport Santa Ana, California burden our gardens with outmoded philosophies and "meaning." The Mrs. Flavia Redelmeier Japanese free their gardens of meaning, allowing the spirit of human nature Richmond Hill, Ontario, Canada to mingle with the genius loci-the spirit of the place. Mrs. Jane N. Scarff New Carlisle, Ohio A recent lecturer at River Farm, Klaus Jurgen-Evert, spoke to us of the Mrs. Josephine Shanks new greenbelt recently completed in Stuttgart, Germany. He showed slides Houston, Texas of impressive new garden displays by American designers Michael Singer Mrs. Billie Trump Alexandria, Virginia and Dan Graham that break from patterns of tradition and reach beyond Mr. Andre Viette European models. Their gardens demand an experience of nature and Fishersv ille, Virginia plants unencumbered by conceptual baggage such as mankind's domina Mrs. Helen Fulcher Walutes tion of nature. These innovations are a good sign for the western horticul Mount Vernon, Virginia Ms. Katy Moss Warner tural tradition. We hope that eastern-inspired creativity continues to Lake Buena Vista, Florida liberate our gardens, enabling them to evolve in a greater and more universal context. Only in this way will horticulture become an important part of people's lives. -George C.
