The appellations “open” and “closed,” however, were not common in American discourse, despite [[Noah Webster|Noah Webster's]] inclusion of such distinctions in his definition. Although these adjectives were not employed to a significant degree, groves fitting these characteristics can be identified. [[Thomas Jefferson]], in his 1807 account of [[Monticello]], described his intention to trim the lower limbs of the trees in his grove, composed of a mixture of hardwoods and evergreens, “so as to give the appearance of open ground,” suggesting an “open” grove [Fig. 2]. [[Eliza Lucas Pinckney]], in 1742, evoked the sense of a “closed” grove when she delineated her collection of trees and flowers. Likewise, in 1776 George Washington suggested a similar type of grove for [[Mount Vernon]], which he described as an arrangement of flowering trees and evergreens underplanted with flowering [[shrub]]s.

Washington’s account of this “closed” grove also provides a significant clue as to the arrangement of plants. In his 1776 letter to Lund Washington, he specified that the trees “be Planted without any order or regularity,” an aesthetic in keeping with the recommendations of Langley, whose treatises were owned by Washington. The texts of Langley and Miller exemplify the gradual shift away from formal or rectilinear arrangements of trees toward more irregular or “[[natural style|natural]]” designs. 17th-century groves might be planted in [[Geometric_style|geometrical]], or otherwise such patterned figures as “the star, the direct Cross, St. Andrew’s Cross,” described by A.-J. Dézallier d’Argenville (1712). By contrast, |Langley insisted that groves be planted with “regular Irregularity; not planting them. . . with their Trees in straight Lines ranging every Way, but in a rural Manner, as if they had receiv’d their Situation from Nature itself.” In contrast to authors of earlier treatises, 19th-century American writers, including Samuel Deane (1790), [[Bernard M’Mahon]] (1806) and the anonymous author of the ''New England Farmer'' (1828), advocated regular arrangements. Few if any signs, however, indicate that Americans made “closed” groves in [[Geometric_style|geometrical]] figures, such as those described in James. [[Pierre Pharoux]]’s unexecuted plans for the new town Sperenza, New York [Fig. 3], and for Baron von Steuben’s estate in Mohawk Valley, New York [Fig. 4], are rare exceptions.
