After marrying in 1925, Peterson devoted most of her time to painting floral subjects. The artist painted in her beautiful gardens at her estate in Ipswich, New York. In 1946, she wrote a how-to book on painting flowers---“Flower Painting”.... She considered part of her success was due to her chosen status as a single woman. For nearly 3 decades she had been able to focus solely on her art. Finally, at 49, Peterson married a wealthy widower, M. Bernard Philipp. For the next 5 years, until his death in 1929, the couple spent winters in New York City and summers at his Rocky Hill estate in Ipswich. Unable to travel and paint in exotic places as was her habit, Peterson began to paint flowers instead. Every summer for the next 25 years, the artist planted, cultivated, and then painted zinnias, peonies, and petunias at Rocky Hill. By the time she died in 1965, ane Peterson had come to be known more for her Ipswich flower paintings than for her views of Paris, Constantinople, Turkey or any of the other exotic locales she had visited in her younger days.
