Harvard educated, this true Renaissance man created extensive gardens embellished with his sculptures and beloved tree peonies at this extensive Pavilion estate in Genesee County, in upstate New York. A friend and assistant to Professor Saunders, Gratwick inherited many of his best tree peony hybrids and continued the breeding program. In addition to importing Paeonia suffruticosa seed from Japan, he selected only the finest flowering forms. Several of his finest introductions, for example 'Guardian of the Monastery' and 'Companion of Serenity' are the standards by which other tree peony varieties are judged. In addition to establishing a tree peony nursery, he breed historic breeds of sheep and show horses, on the estate and authored several privately published books.
