Alley is used in the American setting to describe various forms of walks bordered by plantings on either side, and often appears alongside avenue and walk in treatises and descriptions (see Avenue and Walk). General dictionaries, such as those by Thomas Sheridan and Noah Webster, even define walks and alleys to be synonymous. Despite their similar meanings, however, the term "walk" was more broadly defined in specialist literature; walks occur in a variety of settings outside the garden (for example, rope walks). Alley, despite its frequent use denoting a narrow passage in a town, has a more particular association with the designed landscape than either avenue or walk, having been derived from the French verb aller (to go), which was often associated in British and American gardening treatises with French formal gardens.
The repeated use of the phrase "walks and alleys" in American garden writing suggests that there was a distinction between the two terms, although that nuance of meaning is neither clear nor consistent. In the late seventeenth century, French treatise author Jean de La Quintinie often used the terms "alley" and "walk" interchangeably, and distinguished alleys as more narrow than avenues (view citation). Other treatise writers find the main criteria of an alley to be a walkway formed between two rows of plantings, defined by either low borders, such as in Lewis Beebe's description of flowers lining alleys in a Mr. Pratt's garden (view citation), or by tall, mature shade trees forming an enclosing canopy. This latter definition was exemplified at New Haven Burying Ground (as described by Timothy Dwight in 1796) (view citation), André Parmentier's horticultural and botanical garden [Fig. 1], with its alleys of nectarine, peach, pear, apple, plum, and cherry trees, and Thomas Jefferson's plantation, Monticello [Fig. 2]. In contrast to the treatises, usage examples suggest that alley referred to walkways of all sizes planted on either side, from the pedestrian paths of Gray's Garden in Philadelphia and Jefferson's six-foot-wide "allies" between grass plots at Monticello to the alley wide enough for two carriages to pass at the New Haven Burying Ground. The "Tenpin Alley" in the pleasure grounds of the Pennsylvania Hospital for the Insane [Fig. 3] is an example of the use of the term to describe a site for bowling that looks completely different from the more common garden element, the bowling green (see Bowling green).
Alleys also varied in their configuration. Like walks, they included straight, curved, and zig-zagged designs. An avenue was often planted on either side and was generally straight. An alley, on the other hand, was associated both with the geometric regularity of the ancient style and, as in André Parmentier's usage, with descriptions of winding or serpentine walks in a "modern," more naturalistic garden (compare with Ancient style). It is in this latter context that the Rev. Manasseh Cutler's description of the State House Yard, Philadelphia cites Hogarth's "Line of Beauty," an allusion to mid-eighteenth-century aesthetic theory (view citation) (see Landscape gardening and Picturesque).
In any configuration, alleys functioned much like their counterparts, avenues and walks, in directing views in the landscape and in controlling circulation patterns. Like avenues, straight alleys were used to create an impressive approach to the main house's front entrance and to direct a viewer's gaze toward a focal point or vista. As G. Gregory (1816) advised (), the illusion of depth could be further enhanced by making the alley wider at the entrance than at the termination. Like serpentine walks, a curvilinear alley led garden visitors gradually through the landscape, with each turn revealing a new view or perspective, as conveyed by Cutler's 1787 description (view citation) of Gray's Tavern in Philadelphia.
Treatises describe alleys as usually laid with grass or gravel. The surfaces of American alleys are most commonly described and depicted as gravel, or rolled dirt, although an 1867 description of the garden of Charles Norris in Philadelphia mentions "graveled and grass walks and alleys" (view citation). In many parts of America, the climate was less suited to growing turf than in England, and the surface material was likely selected for its durability, drainage, ease of maintenance, availability, and cost, as well as aesthetic concerns. Archaeological examples suggest packed dirt (as at Arthur Allen's Virginia home, Bacon's Castle), shell, and gravel were used, although none of the walkways at these sites has been associated with the term "alley." Based on extensive excavations at Williamsburg, Va., the quintessential image of the colonial revival garden, the brick walk, does not appear to have been used there (see Walk).

- Anonymous, May 22, 1749, describing Charleston, S.C. (South Carolina Gazette)
- "a garden, genteelly laid out in walks and alleys, with flower-knots, &c. laid round with bricks."
- Cutler, Rev. Manasseh, July 13, 1787, describing State House Yard, Philadelphia, Pa. (1888: 1:263),  back up to history
- "The numerous walks are well graveled and rolled hard; they are all in a serpentine direction, which heightens the beauty, and affords constant variety. That painful sameness, commonly to be met with in garden-alleys, and others works of this kind, is happily avoided here, for there are no two parts of the Mall that are alike. Hogarth's 'Line of Beauty' is here completely verified."
- Cutler, Rev. Manasseh, July 14, 1787, describing Gray's Tavern, Philadelphia, Pa. (1888: 1:275),  back up to history
- "We then rambled over the Gardens, which are large—seemed to be in a number of detached areas, all different in size and form. The alleys were none of them straight, nor were there any two alike. At every end, side, and corner, there were summer-houses, arbors covered with vines or flowers, or shady bowers encircled with trees and flowering shrubs, each of which was formed in a different taste."
- Brissot de Warville, J. P., 1788, describing the State House Yard, Philadelphia, Pa. (1792: 316) 
- "Behind the State-house is a public garden; it is the only one that exists in Philadelphia. It is not large; but it is agreeable, and one may breathe in it. It is composed of a number of verdant squares, intersected by alleys."
- Dwight, Timothy, 1796, describing New Haven Burying Ground, New Haven, Conn. (1821: 1:191–92),  back up to history
- "The field was then divided into parallelograms, handsomely railed, and separated by alleys of sufficient breadth to permit carriages to pass each other. The whole field . . . was distributed into family burying places. . . . Each family burying-ground is thirty-two feet in length, and eighteen in breadth: and against each an opening is made to admit a funeral procession. At the divisions between the lots trees are set out in the alleys: and the name of each proprietor is marked on the railing."
- Beebe, Lewis, 1800, describing a Mr. Pratt's garden (exact location undetermined) (Historical Society of Pennsylvania, Journal of Lewis Beebe, 1799–1801, vol. 3),  back up to history
- "Mr. Pratts garden for beauty and elegance exceeds all that I ever saw—The main alley, 13 feet wide, and 20 rods long is upon each side graced with flowers of every kind and colours—and 18 wide. An alley of 13 feet wide runs the length of the garden thro' the centre—Two others of 10 feet wide equally distant run parallel with the main alley. These are intersected at right angles by 4 other alleys of 8 feet wide—Another alley of 5 feet wide goes around the whole garden, leaving a border around it of 3 feet wide . . . next to the pales. . . . The border of the main alley is ornamented with flowers of every description."
- Jefferson, Thomas, c. 1804, describing Monticello, plantation of Thomas Jefferson, Charlottesville, Va. ("Plan of Spring Roundabout at Monticello," Huntington Library)

- Graydon, Alexander, 1811, describing the garden of Israel Pemberton, Philadelphia, Pa. (pp. 34–35) 
- "laid out in the old fashioned style of uniformity, with walks and allies nodding to their brothers, and decorated with a number of evergreens, carefully clipped into pyramidal and conical forms." [Fig. 5]
- Silliman, Benjamin, 1824, describing Albany, N.Y. (p. 59) 
- "It is perfectly compact—closely built, and as far as it extends, has the appearance of a great city. It has numerous streets, lanes, and alleys, and in all of them, there is the same closeness of building, and the same city-like appearance."
- Willis, Nathaniel Parker, 1840, quoting an early visitor's description of Mount Vernon, plantation of George Washington, Fairfax County, Va. ( 1971: 263) 
- "At the extremity of these extensive alleys and pleasure-grounds, ornamented with fruit-trees and shrubbery, and clothed in perennial verdure, stands two hot-houses, and as many green-houses, situated in the sunniest part of the garden, and shielded from the northern winds by a long range of wooden buildings for the accommodation of servants."
- Hovey, C. M., September 1851, "Notes on Gardens and Nurseries," describing Rose Hill, residence of George Leland, Waltham, Mass. (Magazine of Horticulture 17: 411) 
- "A main walk extends around the garden, with alleys leading from one side to the other."
- Logan, Deborah Norris, 1867, describing the garden of Charles Norris, Philadelphia, Pa. (p. 6),  back up to history
- "It was laid out in square parterres and beds, regularly intersected by graveled and grass walks and alleys."

- "Where is the person, gifted with any taste, who would not choose those alleys that wind without constraint, in preference to those dull straight lines which can be measured by one glance of the eye, and the monotony of which is unvaried?

- "But instead of planting these trees in formal close orchard lines, we should dot them about apparently irregularly, but in reality with some plan, at sufficient distances to permit, when full grown, intervals of parterres of flowers; and under each tree we should spread a circular carpet of verdant grass, kept well mown, on which the ripe and bursting peach might fall uninjured, and the disfiguring tread of the gatherer be unseen. The connexion of these circular grass plots by means of trellises of the vine, or variously formed beds of herbaceous and annual flowers, with here and there a screen of three or four thick shrubs, to conceal and protect from early blasts, a bijou or jewel of a recess set apart for small masses of choice flowers, which may suddenly and unexpectedly burst on the wanderer through the alleys—these and a variety of other schemes will afford exercise to the man of taste, and create interest in the visitor."
- "All the large divisions [of a flower garden] should be intersected by small alleys, or paths, about one and a half or two feet wide."

- "Where a taste for imitating an old and quaint style of residence exists, the symmetrical and knotted garden would be a proper accompaniment; and pleached alleys, and sheared trees, would be admired, like old armor or furniture, as curious specimens of antique taste and custom. . . .
- "In these gardens, nature was tamed and subdued. . . . The stately etiquette and courtly precision of the manners of our English ancestors, extended into their gardens, and were reflected back by the very trees which lined their avenues, and the shrubs which surrounded their houses . . . the gay ladies and gallants of Charles II's court . . . fluttering in glittering processions, or flirting in green alleys and bowers of topiary work."
