Fig. 1, Anonymous, Surveyor’s plat of the courthouse and adjacent land Charles County, MD, 1697. The trees in the lower part of the image are labeled “Thickett” on the right edge.

Although thicket is not mentioned as frequently as other planting terms in 18th- and 19th-century garden literature, it is nonetheless significant as a description for naturally occurring and designed features [Fig. 1]. According to Thomas Whately, whose 1770 definition was quoted or paraphrased by garden writers for the next century, a thicket was a dense planting of woods underplanted with shrubs, akin to a closed clump or copse. British treatise author Charles Marshall (1799) used “coppice” synonymously with “thicket.” American writers such as Bernard M’Mahon (1806) offered similar definitions, describing a thicket as closely planted trees with shrubs. It was distinguished from a clump, copse, or wood by its compactness and smaller scale.

This connotation was found in American accounts written by Eliza Lucas Pinckney (1743), Manasseh Cutler (1787 and 1802), and Thomas Jefferson (1806). A more detailed portrayal of thicket was provided by Jefferson in a letter of 1804. In this document, he indicated which plants to include in the thicket, such as azaleas and rhododendrons, and also noted how a thicket might be planted in a spiral or labyrinth formation with walks between rows of plants. Such forms and materials were quite close to those formed in wilderness hedges or graduated shrubberies.

The plants used to compose thickets varied widely. Pinckney, for example, described a thicket of young oaks at William Middleton’s plantation, Crowfield, near Charleston. Jefferson, in addition to suggesting a variety of flowering shrubs, envisioned thickets made entirely of evergreens and other nonflowering plants in his 1806 letter to William Hamilton. The array of plants recommended by Jefferson was consistent with the advice given by contemporary treatise authors, such as M’Mahon, who promoted combinations of hardy deciduous or evergreen trees and shrubs.

As design elements, thickets were used in many ways. They marked boundaries, directed one’s gaze toward preferred views, and screened out undesirable views. Such functions depended upon the density of thicket plantings, and garden literature suggests that thickets were considered akin to impenetrable hedges or dense shrubberies and other boundary markers. For example, c. 1800 the designer of the Elias Hasket Derby House in Salem, Massachusetts, noted that a thicket could be replaced by a ha-ha or sunk fence to mark the perimeter of the garden. Jefferson, in 1806, described how at Monticello thickets could be used to circumscribe views. By 1850, A. J. Downing, in his article “How to Arrange Country Places,” stated that thickets should be planted to keep out “unbidden guests.” Downing also recommended the use of tall, dense thickets to screen the sides of walks in order to re-create the romantic experience of walking undisturbed in an uncultivated wood.

Thickets, as M’Mahon noted, were also placed along the outer edges of lawns in order to break up the formality of a smooth lawn and to create a setting consistent with the natural or picturesque style. Not only was this strategy in accord with the theories of landscape gardening, it also suited the American gardener’s challenge to carve out a garden from what was often heavily wooded land. Jefferson, for example, described cutting away existing vegetation at Monticello to create a series of ordered woods, clumps, and hemispherical thickets. Ironically, less than fifty years later, George Jaques (1851) suggested the reverse of this process, recommending that thickets be planted in the midst of commons in order to recall the primeval forests that once covered North America.

“Next to that on the right hand is what imediately struck my rural taste, a thicket of young tall live oaks where a variety of Airry Chorristers pour forth their melody.”

  • Kalm, Pehr, September 21, 1748, describing the vicinity of Philadelphia, PA (1937: 1:47)[2]
“The common privet, or Ligustrum vulgare L., grows among the bushes in thickets and woods.”

“At this hermitage we came into a spacious graveled walk, which directed its course further along the grove, which was tall wood interspersed with close thickets of different growth. As we advanced, we found our gravel walk dividing itself into numerous branches, leading into different parts of the grove.”

Fig. 2, Anonymous, Plan for the garden of the Elias Hasket Derby House, c. 1795-99.
  • Anonymous, c. 1800, describing Elias Hasket Derby Farm, Peabody, MA (Peabody Essex Institute, Phillips Library, Derby Papers)
“If there is any Prospect that is agreeable can be seen from the House make a Ha-Ha instead of a Thicket.” [Fig. 2]

“The side of the steep bank to the river is covered with a thicket of forest trees in its whole extent within view of the house.”

Fig. 3, Thomas Jefferson, Letter describing plans for a “Garden Olitory,” c. 1804. The spiral diagram indicates a thicket.
  • Jefferson, Thomas, c. 1804, describing Monticello, plantation of Thomas Jefferson, Charlottesville, VA (quoted in Nichols and Griswold 1978: 111–12)[4]
“The canvas at large must be Grove, of the largest trees, (poplar, oak, elm, maple, ash, hickory, chestnut, Linden, Weymouth pine, sycamore) trimmed very high, so as to give it the appearance of open ground, yet not so far apart but that they may cover the ground with close shade.
“This must be broken by clumps of thicket, as the open grounds of the English are broken by clumps of trees. plants for thickets are broom, calycanthus, altheas, gelder rose, magnolia glauca, azalea, fringe tree, dogwood, red bud, wild crab, kalmia, mezereon, euonymous, halesia, quamoclid, rhododendron, oleander, service tree, lilac, honeysuckle, brambles. [Fig. 3]
“Vistas to very interesting objects may be permitted, but in general it is better so to arange the thickets as that they may have the effect of vista in various directions. . . .
“a thicket may be of Cedar, topped into a bush, for the center, surrounded by Kalmia. or it may be of Scotch broom alone.”

  • Jefferson, Thomas, July 1806, describing Monticello, plantation of Thomas Jefferson, Charlottesville, VA (1944: 323–24)[5]
“The grounds which I destine to improve in the style of the English gardens are in a form very difficult to be managed. . . . They are chiefly still in their native woods. which are majestic, and very generally a close undergrowth, which I have not suffered to be touched, knowing how much easier it is to cut away than to fill up. The upper third is chiefly open, but to the South is covered with a dense thicket of Scotch broom (Spartium scoparium Lin.) which being favorably spread before the sun will admit of advantageous arrangement for winter enjoyment. . . .
“Let your ground be covered with trees of the loftiest stature. Trim up their bodies as high as the constitution & form of the tree will bear, but so as that their tops shall still unite & yield dense shade. A wood, so open below, will have nearly the appearance of open grounds. Then, when in the open ground you would plant a clump of trees, place a thicket of shrubs presenting a hemisphere the crown of which shall distinctly show itself under the branches of the trees. This may be effected by a due selection & arrangement of the shrubs, & will I think offer a group not much inferior to that of trees. The thickets may be varied too by making some of them of evergreens altogether, our red cedar made to grow in a bush, evergreen privet, pyrocanthus, Kalmia, Scotch broom. Holly would be elegant but it does not grow in my part of the country.
“Of prospect I have a rich profusion and offering itself at every point of the compass. Mountains distant & near, smooth & shaggy, single & in ridges, a little river hiding itself among the hills so as to shew in lagoons only, cultivated grounds under the eye and two small villages. To present a satiety of this is the principal difficulty. It may be successively offered, & in different portions through vistas, or which will be better, between thickets so disposed as to serve as vistas, with the advantage of shifting the scenes as you advance your way.”

“[At the Temple of Solitude in the woodland] . . . on the right appears a dark and almost impenetrable thicket, skirting and overshadowing the rivulet.”

  • Kemble, Fanny, January 1839, describing her husband’s plantations on Butler Island, GA (1984: 56)[7]
“My walks are rather circumscribed, inasmuch as the dikes are the only promenades. On all sides of these lie either the marshy rice fields, the brimming river, or the swampy patches of yet unreclaimed forest, where the huge cypress trees and exquisite evergreen undergrowth spring up from a stagnant sweltering pool, that effectually forbids the foot of the explorer.
“As I skirted one of these thickets today, I stood still to admire the beauty of the shrubbery.”

“Its richness of foliage, both in natural wood and planted trees, is one of its marked features. Indeed, so great is the variety and intricacy of scenery, caused by the leafy woods, thickets and bosquets, that one may pass days and even weeks here, and not thoroughly explore all its fine points.”

  • Jaques, George, February 1851, “Trees in Cities,” describing Worcester, MA (Magazine of Horticulture 17: 52)
“Suppose the trees upon the Common were gathered together in groups,—here a thicket, there a wide space of open lawn; or suppose the primitive forest,—such as perhaps once grew there,—had remained, and clearings been made with a bold hand to let in the sunshine, would you not prefer either of these conditions to the present one, beautiful as it may be?”


“A small thicket is generally most agreeable, when it is one fine mass of well-mixed greens: that mass gives to the whole a unity, which can by no other means be so perfectly expressed. When more than one is necessary for the extent of the plantation, still if they are not too much contrasted, if the gradations from one to another are easy, the unity is not broken by the variety. . . .
“A wood is composed both of trees and underwood, covering a considerable space. A grove consists of trees without underwood; a clump differs from either only in extent; it may be either close or open; when close, it is sometimes called a thicket; when open, a groupe of trees; but both are equally clumps, whatever be the shape or situation.”

  • Marshall, Charles, 1799, An Introduction to the Knowledge and Practice of Gardening (1:119)[10]
“As to small plantations, of thickets, coppices, clumps, and rows of trees, they are to be set close according to their nature, and the particular view the planter has, who will take care to consider the usual size they attain, and their mode of growth. An advantage at home for shade or shelter, and a more distant object of sight, will make a difference: for some immediate advantage, very close planting may take place, but good trees cannot be thus expected; yet if thinned in time, a strait tall stem is often thus procured, which afterwards is of great advantage.”

“First an open lawn of grass-ground is extended on one of the principal fronts of the mansion or main house, widening gradually from the house outward, having each side bounded by various plantations of trees, shrubs, and flowers, in clumps, thickets, &c. exhibited in a variety of rural forms, in moderate concave and convex curves, and projections, to prevent all appearance of a stiff uniformity. . . .
Thickets may be composed of all sorts of hardy deciduous trees planted close and promiscuously, and with various common shrubs interspersed between them, as underwood, to make them more or less close in different parts, as the designer may think proper. They may also be of ever-green trees, particularly of the pine and fir kinds, interspersed with various low-growing ever-green shrubs.”

“A thicket differs from a clump, in comprising thorns and underwood as well as trees, while it is too small to be called a wood. It admits more variety and wildness than the clump; but should be farther removed from the polished lawn.”

Fig. 4, J. C. Loudon, Thicket [detail], in An Encyclopaedia of Gardening (1826), p. 942, figs. 628b and c.
“6811. In regard to extent, the least is a group. . . which must consist at least of two plants; larger, it is called a thicket (b c); round and compact, it is called a clump (a); still larger, a mass; and all above a mass is denominated a wood or forest, and characterised by comparative degrees of largeness. The term wood may be applied to a large assemblage of trees, either natural or artificial; forest, exclusively to the most extensive or natural assemblages. . . . [Fig. 4]
Fig. 5, J. C. Loudon, The placement of groups and thickets in plantations, in An Encyclopaedia of Gardening (1826), p. 954, fig. 649.
“6861. Placing the groups. Another practice in the employment of groups, almost equally reprehensible with that of indiscriminate distribution, is that of placing the groups and thickets in the recesses, instead of chiefly employing them opposite the salient points. The effect of this mode is the very reverse of what is intended; for, instead of varying the outline, it tends to render it more uniform by diminishing the depth of recesses, and approximating the whole more nearly to an even line. The way to vary an even or straight line or lines, is here and there to place constellations of groups against it . . . and a line already varied is to be rendered more so, by placing large groups against the prominences (a) to render them more prominent; and small groups (b), here and there in the recesses, to vary their forms and conceal their real depths.” [Fig. 5]

  • Buist, Robert, 1841, The American Flower Garden Directory (1840: 20)[14]
“Thick masses of shrubbery, called thickets, are sometimes wanted. In these there should be plenty of evergreens. A mass of deciduous shrubs has no imposing effect during winter.”

  • Downing, A. J., 1849, A Treatise on the Theory and Practice of Landscape Gardening (1849: 93, 95, 104–5, 112–13, 119–20, 250)[15]
“were a person to desire a residence newly laid out and planted, in a district where all around is in a high state of polished cultivation, as in the suburbs of a city, a species of pleasure would result from the imitation of scenery of a more spirited, natural character, as the picturesque, in his grounds. His [the homeowner] plantations are made in irregular groups, composed chiefly of picturesque trees, as the larch, &c.—his walks would lead through varied scenes . . . sometimes with thickets or little copses of shrubs and flowering plants. . . .
Fig. 6, Anonymous, “Plan of the foregoing grounds as a Country Seat, after ten years' improvement,” in A. J. Downing, A Treatise on the Theory and Practice of Landscape Gardening (1849), p. 114, fig. 24. At b this plan depicts “varied walks concealed from each other by the intervening masses of thicket.”
“And as the Avenue, or the straight line, is the leading form in the geometric arrangement of plantations, so let us enforce it upon our readers, the GROUP is equally the key-note of the Modern style. The smallest place, having only three trees, may have these pleasingly connected in a group; and the largest and finest park—the Blenheim or Chatsworth, of seven miles square, is only composed of a succession of groups, becoming masses, thickets, woods. . . .
“In order to know how a plantation in the Picturesque mode should be treated, after it is established, we should reflect a moment on what constitutes picturesqueness in any tree. . . . He [the cultivator of trees] desires to encourage a certain wildness of growth, and allows his trees to spring up occasionally in thickets to assist this effect. . . .
Fig. 7, Anonymous, “View of a Picturesque farm (ferme ornée),” in A. J. Downing, A Treatise on the Theory and Practice of Landscape Gardening (1849), p. 120, fig. 27. In describing this plan, Downing refers to “a low dell, or rocky thicket” that is situated at “i” in the densley planted area in the triangle at top.
“In the next figure . . . a ground plan of the place is given, as it would appear after having been judiciously laid out and planted, with several years’ growth. At a, the approach road leaves the public highway and leads to the house at c: from whence paths of smaller size, b, make the circuit of the ornamental portion of the residence, taking advantage of the wooded dells, d, originally existing, which offer some scope for varied walks concealed from each other by the intervening masses of thicket. . . . [Fig. 6]
“The embellished farm (ferme ornée) is a pretty mode of combining something of the beauty of the landscape garden with the utility of the farm, and we hope to see small country seats of this kind become more general. . . . A low dell, or rocky thicket, is situated at i. . . . [Fig. 7]
“The Hawthorn is most agreeable to the eye in composition when it forms the undergrowth or thicket, peeping out in all its green freshness, gay blossoms, or bright fruit, from beneath and between the groups and masses of trees; where, mingled with the hazel, etc., it gives a pleasing intricacy to the whole mass of foliage. But the different species display themselves to most advantage, and grow also to a finer size, when planted singly, or two or three together, along the walks leading through the different parts of the pleasure-ground or shrubbery.”

  • Downing, A. J., March 1850, “How to Arrange Country Places” (Horticulturist 4: 396)
“In residences where there is little or no distant view, the contrary plan must be pursued. Intricacy and variety must be created by planting. Walks must be led in various directions, and concealed from each other by thickets, and masses of shrubs and trees, and occasionally rich masses of foliage; not forgetting to heighten all, however, by an occasional contrast of broad, unbroken surface of lawn.
“In all country places, and especially in small ones, a great object to be kept in view in planting, is to produce as perfect seclusion and privacy within the grounds as possible. We do not entirely feel that to be our own, which is indiscriminately enjoyed by each passer by, and every man’s individuality and home-feeling is invaded by the presence of unbidden guests. Therefore, while you preserve the beauty of the view, shut out, by boundary belts and thickets, all eyes but those that are fairly within your own grounds. This will enable you to feel at home all over your place.”

  • Downing, A. J., September 1851, “Study of Park Trees” (Horticulturist 6: 427)
“Even in our ornamental grounds, it is too much the custom to plant trees in masses, belts, and thickets—by which the same effects are produced as we constantly see in ordinary woods— that is, there is picturesque intricacy, depth of shadow, and seclusion, growing out of masses of verdure—but no beauty of development in each individual tree—and none of that fine perfection of character which is seen when a noble forest tree stands alone in soil well suited to it, and has ‘nothing else to do but grow’ into the finest possible shape that nature meant it to take.”
