In his domestic establishment the planter sought to reproduce as nearly as he conveniently could the residence of the English gentry with its gardens, lawns, and parks. Plans of English homes and gardens, which intelligent workmen or even a layman might adapt, were accessible in the handbooks of architecture and gardening found in many of the planters' libraries. In some instances the striking similarity of detail leaves little doubt that the plans for a planter's residence derived directly from plates in these books. All the forms common to the English country architecture of the period were employed in the plantation residences. Sometimes English master builders and gardeners were imported to supervise the construction of the residences and the planting of the grounds. The vogue for formality in English architecture and landscaping was mirrored in the arrangement of the Virginia estates. The mansions were generally placed according to carefully preconceived plans in a formal setting which nonetheless managed to achieve an air of ease and naturalness. Balance and symmetry were observed everywhere, with the buildings, gardens, and extensive lawns forming component parts of one composition. Walks of brick or oyster shell crossed the grounds in geometric pattern. If a bowling green or formal garden flanked one side of the mansion, an orangery or perhaps a park stocked with deer flanked the other. English box and other ornamental plants were used with fine effect. Terraces, elaborate parterres, sunken panels, canals, and dramatic vistas gave variety to the scene. "Falling gardens" were popular at the residences situated on high eminences overlooking the great rivers and marshes.[14] Not infrequently, as at "Blandfield," a ha-ha provided a note of pleasant surprise for one walking on the lawns.[15] Graceful garden houses, dovecots, and other miniature structures, carefully placed, sometimes imparted a fanciful atmosphere to the whole. Every estate had its orchard, the fruit of which surpassed the choicest specimens of the homeland. Wildernesses or preserves of transplanted trees might be found at some distance from the residence, and sometimes serpentine drives and walks invited one to explore hidden retreats. [14] A "falling garden" consisted of a series of very broad terraces, usually connected by ramps covered with turf, oyster shell or other surface material to prevent erosion. In some instances the successive levels were planted in elaborate patterns. In others the whole was covered with turf. The "falling garden" at "Sabine Hall" retains its eighteenth-century design intact.
