Bartram Botanic Garden and Nursery
The Bartram Botanic Garden and Nursery, located on the west bank of the Schuylkill River in Philadelphia, is the oldest surviving garden in the United States. In the eighteenth century it contained an encyclopedic collection of indigenous American plants (many discovered by Bartram) as well as exotics sent to him from other parts of the world.

located on the west bank of the Schuylkill River in Philadelphia, was developed by John Bartram both scientific and commercial purposes. He cultivated an encyclopedic range of plants, both native examples discovered on his explorations and exotic specimens sent to him from other parts of the world.
Through a number of property transactions made between 1728 and 1740, John Bartram acquired over 287 acres of rich, well-watered farmland on the Schuylkill River at Kingsessing, about three miles from the center of Philadelphia. The land had been in use since the mid seventeenth century and Bartram devoted most of it to agriculture. In addition to cultivating grains and raising livestock, he planted a kitchen garden in 1729 and built a stone farmhouse in 1731.Cite error: Closing

<ref> tag A drawing of 1758 that Bartram sent to Peter Collinson in London identifies no specific plant materials, but clearly indicates the layout as a terraced garden consisting of four well-defined zones. Directly behind the house is a “Common Flower Garden,” with an “Upper Kitchen Garden” to its north and “A new flower Garden,” measuring twenty-six by ten yards, to the south. Board fences separate each garden from the others. A stone retaining wall punctuated by steps articulates the descent from this upper zone to the lower and much larger “Long Kitchen Garden” sloping down to the banks of Schuylkill River. Three long alleys of trees run the full length of the garden, creating “Walks 150 yards long of a moderate descent.” Following his visit to the property in 1787, Manasseh Cutler noted “a walk to the river, between two rows of large, lofty trees,” adding that the trees were of “all of different kinds.” An oval-shaped pond at the center of the lower garden connects to the “spring or milk House” located in the shade of a large tree near the garden’s northern fence. Plantings interspersed along the fence may represent espaliered trees.
Bartram’s extensive field experience distinguished him from most of the gardeners and botanists of his day. Informed by his knowledge of the natural habitats of plants, he reserved the wilder areas that lay beyond his enclosed kitchen and flower gardens well-articulated space near the house were wilder areas characterized by varying environmental conditions, where Bartram was able to “nurs[e] up his idol flowers and cultivat[e] his darling productions” in conditions that approximated the natural habitats in which he had first encountered them (view text). It was there that he cultivated many of the native plants gathered while exploring wilderness areas from New York to Florida. The garden was shaped by practical rather than ornamental concerns. Bartram’s insatiable botanical curiosity and far-ranging expeditions placed a premium on comprehensiveness, as did the function of his garden and nursery as a supplier of plants for sale and exchange. Initiating a trading relationship with J. Slingsby Cressy, a physician an botanist in Antigua, Bartram emphasized the breadth of his interests: “Whatsoever whether great or small ugly or handsom sweet or stinking…every thing in the universe in their own nature appears beautiful to mee,” Twenty years later, in a letter to his English friend and correspondent Peter Collinson, he crowed, “I can challenge any garden in America for variety.”Cite error: Closing

Despite his love of variety, Bartram was reluctant to cultivate delicate plants that required inordinate care to survive Philadelphia’s climate. “I don’t greatly like tender plants what wont bear our severe winters,” he remarked to Philip Miller (1791-1771), curator of the Chelsea Physick Garden, in a letter of June 20, 1757 (view text) This position changed somewhat in 1760, the year of Bartram’s first visit to South Carolina, when he decided to build a greenhouse. As he explained to Peter Collinson, his plan was to construct the building of stone and to grow “some pretty flowering winter shrubs, and plants for winter’s diversion,” rather than the orange trees and tropical plants nurtured in the more opulent greenhouses of several of Bartram’s neighbors. Bartram erected a modest, one-and-a-half story building of stone with an east facing window, which was completed by December 1762 when he informed Collinson that he had included an external fireplace and two flues in the back wall for heat. From the 1760s on, the addition of warm-weather Carolina plants transformed Bartram’s garden, enlivening it with brilliantly colored flowers that he delighted in. 
From an early date Bartram provided trees, shrubs, bulbs, roots, and seeds to many of his neighbors in Philadelphia, including William Hamilton of The Woodlands, Charles Willson Peale of Belfield, and Thomas Penn of Springettsbury. His business expanded exponentially after he entered into an informal partnership with the London merchant Peter Collinson who was his faithful correspondent and advocate for over thirty years. With the encouragement of Collinson and a growing British and European clientele, Bartram traveled to most of the American colonies, collecting unusual plants and seeds to transplant and cultivate at his garden. During Bartram’s frequent absences from home on botanical expeditions, the garden was managed by his wife, Ann Mendenhall Bartram (1703–1789). Despite the disruption in trade caused by the American Revolution, the commercial nursery business continued to flourish through to the end of the eighteenth century, as a burgeoning domestic market joined the overseas trade. Bartram's business was still thriving as it approached its third decade. “I must inlarge my nursery garden,” he informed a friend in August 1769.
Following the death of John Bartram in 1777, the nursery business continued under the supervision of John Bartram, Jr. with assistance from his elder brother, the natural history explorer and illustrator William Bartram. Under their watch, the garden became an outdoor classroom. Benjamin Smith Barton, the first professor of natural history at the University of Pennsylvania, brought his students to the garden to study live plants in situ, and the Bartrams noted with pride that their family’s botanic garden “may with propriety and truth be called the Botanical Academy of Pennsylvania, since…the Professors of Botany, Chemistry, and Materia Medica, attended by their youthful train of pupils, annually assemble here during the Floral season. John Bartram’s children continued to expand the business, adding a second greenhouse was added around 1790, and another in 1817.  The fame of the garden attracted many distinguished visitors. George Washington visited the garden on June 10 and September 2, 1787 while in Philadelphia for the Continental Convention.  Although he disparaged the garden in his diary, describing it as “not laid off with much taste, nor was it large,” he was impressed by the many “curious pl[an]ts. Shrubs & trees, many of which are exotics.” (view text). Two years later he requested a catalog from the Bartrams (view text) and in 1792 ordered at least 106 varieties of plants. Three hundred trees and shrubs from Bartrams Garden were planted in ornamental ovals at Mount Vernon that spring.
In 1807 the Bartrams distributed “A Catalog of Trees, Shrubs, and Herbaceous Plants Indigenous to the United States of America, cultivated and Disposed of by John Bartram and Son at their Botanical Garden at Kingessing, near Philadelphia. To which is added a Catalog of Foreign Plants Collected from Various Parts of the Globe.” By that time, John Jr. had brought in his, James Howell Bartram, to assist in managing the garden. As the elder Bartram explained in the introduction to the catalog: “Finding old age coming on, he has lately associated his son with him in the concern and hopes by their united exertions, the gardens will continue to be worthy of the attention of the lovers of science and the admirers of nature.” After 1812, Bartram’s daughter, Ann Bartram Carr, was responsible for maintaining the garden and operating the business. She had learned the science of botany and the art of botanical illustration from her uncle William and together with her husband Colonel Robert Carr and his son John Bartram Carr (1804-1839) she enlarged the commercial nursery and continued the international trade in seeds and plants. At its peak the enterprise operated ten greenhouses and maintained a collection of over 1400 native and 1000 exotic plant species.<Fry 2004, 5> In 1838 the Philadelphia, Wilmington and Baltimore Rail Road laid out the first route south of Philadelphia, cutting through the west side of the Bartram-Carr property. Later in the century, the single track was expanded to two tracks. Having continued to grow and thrive through three generations of the Bartram family, Bartram's Botanic Garden and Nursery began to experience financial difficulties and was sold out of the family in 1850. The historic garden was purchased by the wealthy railroad industrialist Andrew M. Eastwick (1811-1879), who maintained it as a private park. <Fry, 2004, 5> Today it is a 45-acre National Historic Landmark, operated by the John Bartram Association in cooperation with Philadelphia Parks and Recreation

- "Near Philadelphia I found the botanic garden of Messrs. John and William Bartram. This is likewise an old establishment, founded under the patronage of the late Dr. Fothergill, by the father of the now living Bartrams. This place, delightfully situated on the banks of the Delaware, is kept up by the present proprietors, and probably will increase under the care of the son of John Bartram, a young gentleman of classical education, and highly attached to the study of botany. Mr. William Bartram, the well known author of “Travels through North and South Carolina,” I found a very intelligent, agreeable, and communicative gentleman; and from him I received considerable information about the plants of that country, particularly respecting the habitats of a number of rare and interesting trees. It is with the liveliest emotions of pleasure I call to mind the happy hours I spent in this worthy man’s company, during the period I lived in his neighbourhood.

- " I spent several hours yesterday with our worthy old friend BARTRAM; and have made an arrangement with Col. ROBERT CARR, who has the management of the garden, to cultivate my S. American plants. He has now the Lantana Bratrami [sic] (for the first time) in flower in his garden…. Mrs. CARR (daughter of the late JOHN BARTRAM,) draws elegantly,— and has engaged to execute as many drawings for me as I want…..
- “I found yesterday…a new species of Prunella….On showing a specimen of it to Mr. BARTRAM, he thought he had seen it, — and considered it a new species. He will search for it, and let me know."
- "Mr. Bartram was the first native American who conceived and carried into effect the plan of a botanical garden for the reception and cultivation of indigenous as well as exotic plants, and of travelling for the purpose of accomplishing this plan. He purchased a situation on the banks of Schuylkill, and enriched it with every variety of the most curious and beautiful vegetables, collected in his excursions, which his sons have since continued to cultivate."
- Committee of the Pennsylvania Horticultural Society, 1830, describing Bartram Botanic Garden and Nursery (quoted in Boyd 1929: 428) 
- “Mr. Carr’s fruit nursery has been greatly improved, and will be enlarged next spring to twelve acres—its present size is eight. The trees are arranged in systematical order, and the walks well gravelled. The whole is abundantly stocked, from the seed bed to the tree. Here are to be found 113 varieties of apples, 72 of pears, 22 of cherries, 17 of apricots, 45 of plums, 39 of peaches, 5 of nectarines, 3 of almonds, 6 of quinces, 5 of mulberries, 6 of raspberries, 6 of currants, 5 of filberts, 8 of walnuts, 6 of strawberries, and 2 of medlars. The stock, considered according to its growth, has in the first class of ornamental trees, esteemed for their foliage, flowers, or fruit, 76 sorts; of the second class 56 sorts; of the third class 120 sorts; of ornamental evergreens 52 sorts; of vines and creepers, for covering walls and arbours, 35 sorts; of honey suckle 30 sorts, and of roses 80 varieties.”
- Wynne, William, 1832, “Some Account of the Nursery Gardens and the State of Horticulture in the Neighbourhood of Philadelphia,” describing the Bartram Botanic Garden and Nursery (Gardener’s Magazine 8: 272–73)
- “I shall begin with Bartram’s Botanic Garden; the precedence being due to it, both for antiquity (it having been established 100 years), and from its containing the best collection of American plants in the United States. There are above 2000 species (natives) contained in a space of six acres, not including the fruit nursery and vineyard, which comprise eight acres. . . . Indeed, the most remarkable feature in this nursery, and that which renders it superior to most of its class, is the advantage of possessing large specimens of all the rare American trees and shrubs; which are not only highly ornamental, but likewise very valuable, from the great quantities of seed they afford for exportation to London, Paris, Petersburgh, Calcutta, and several other parts of Europe, Asia, and Africa. This garden is the regular resort of the learned and scientific gentlemen of Philadelphia.”

- “It is with deep regret that we learn that one of the principal rail roads in the State of Pennsylvania, now constructing, will run to the city directly through the nursery of Col. Carr, and will cut up the grounds in such a manner as to entirely destroy their beauty; but what is a source of yet deeper regret, is the destruction which it will cause of some of the old and still beautiful specimens of trees which ornament the place; several of these, which have long served as a memento of the zealous labors of the elder Bartram and his sons, will fall by the woodman’s axe. It is a melancholy scene to the American horticulturist to see the few beautiful private residences and nurseries of which our country can boast, one by one, purchased by individuals or companies, to be cut up into building lots, or otherwise destroyed, by rail roads running directly through them. Dr. Hosack’s, at Hyde Park, N.Y., the best specimens of gardening in this country, was the first; Mr. Pratt’s, Laurel [Lemon Hill]], but little inferior in its style, next; and now one of the oldest nurseries, bounded by one of the best naturalists this country ever produced, is to follow, though not the same, a similar fate.”
- [[François André Michaux, 1841, describing the Bartram Oak at the Bartram Botanic Garden and Nursery (1: 37) 
- "Every botanist who has visited different regions of the globe must have remarked certain species of vegetables which are so little multiplied that they seem likely at no distant period to disappear from the earth. To this class belongs the Bartram Oak. Several English and American naturalists who, like my father and myself, have spent years in exploring the United States, and who have obligingly communicated to us the result of their observations, have like us, found no traces of this species except a single stock in a field belonging to Mr. Bartram, on the banks of the Schuylkill, 4 miles from Philadelphia…. [Fig. X]
- "Several young plants, which I received from Mr. Bartram himself, have been placed in our public gardens to insure the preservation of the species."
- “He [John Bartram] was, perhaps, the first Anglo-American who conceived the idea of establishing a BOTANIC GARDEN for the reception and cultivation of the various vegetables, natives of the country, as well as exotics, and of travelling for the discovery and acquisition of them.
- “* The BARTRAM BOTANIC GARDEN, (established in or about the year 1730,) is most eligibly and beautifully situated, on the right bank of the river Schuylkill, a short distance below the city of Philadelphia. Being the oldest establishment of the kind in this western world, and exceedingly interesting, from its history and associations,—one might almost hope, even in this utilitarian age, that, if no motive more commendable could avail, a feeling of state or city pride, would be sufficient to ensure its preservation, in its original character, and for the sake of its original objects. But, alas! there seems to be too much reason to apprehend that it will scarcely survive the immediate family of its noble-hearted founder,—and that even the present generation may live to see the accumulated treasures of a century laid waste—with all the once gay parterres and lovely borders converted into lumberyards and coal-landings.”
- “884. At and near Philadelphia are Bartram’s botanic garden, now the nursery of Colonel Carr, and accurately described by his foreman, Mr. Wynne (Gard. Mag., vol. viii. p. 272.); Messrs. Landreth and Co.’s nursery; and that of Messrs. Hibbert and Buist; besides some commercial gardens in which, to a small nursery with green and hot-houses, are added the appendages of a tavern. These tavern gardens, Mr. Wynne informs us, are the resort of many of the citizens of Philadelphia, more especially the gardens of M. Arran, and M. d’Arras; the first having a very good museum, and the latter a beautiful collection of large orange and lemon trees."
