More than two decades were spent in writing and producing Hortus Third. It is the outgrowth of a program of research in the systematics of cultivated plants, initiated in the late nineteenth century by Liberty Hyde Bailey and continuing today within the framework of his philosophy that knowledge in basic science should be made available to society as a whole. Hortus Third is for advanced horticulturists and others interested in cultivated plants, including horticultural and garden writers, gardeners, nurserymen, landscape architects, botanists, and professional scientists in universities, botanical gardens, extension services, and government.

Hortus Third was written by the staff of the Liberty Hyde Bailey Hortorium of Cornell University with the collaboration of a long list of distinguished contributors. The final editing and revisions were the responsibility of the professional staff of the Hortorium, David M. Bates, John W. Incram, Jr., and Harold E. Moore, Jr.
