The Formal Garden remains virtually as Joseph Jr. designed it — mirror images in two rows of plantings separated by lawn and ending at the cedar of Lebanon. The original beds contained a minimum of plant material — hostas, junipers, hemlocks and rose hybrids that reinforced the strong lines of the overall house. After Howard moved to the property in 1939, he brought both his architectural background and landscape painting talents to bear, expanding the plantings and experimenting with color and form. He added azaleas, rhododendrons, high bush blueberries, bulbs and annuals. Liquidambar styraciflua ‘Slender Silhouette,’ a cultivar of American sweetgum, now forms living columns that extend the architectural lines of the house into the surroundings.
