John Bartram (March 23, 1699 – September 22, 1777), an American-born botanist, horticulturalist, and explorer, established the Bartram Botanic Garden and Nursery near Philadelphia. He made significant contributions to the collection, study, and international dissemination of North American flora and fauna, and was a pioneer in the importation and cultivation of non-native plants.


Fig. 1, John or William Bartram, "A Draught of John Bartram's House and Garden as it appears from the River," 1758

The son of a Quaker farmer in rural Pennsylvania, John Bartram possessed from an early age a “great inclination to botany & natural history,” which he pursued through exploration and independent study.[1] In his late twenties, Bartram purchased farm land on the banks of the lower Schuylkill River a few miles from Philadelphia, reserving a half dozen acres for gardens.[2] While exploring the surrounding countryside, he foraged for local plants — both for his garden, and for his friends Benjamin Franklin and Joseph Breintnall (d. 1746), who in the early 1730s were creating a comprehensive set of nature prints documenting indigenous leaf and grass specimens.[3] In 1733 Breintnell sent a set of the prints to Peter Collinson, an enterprising merchant and Fellow of the Royal Society in London.[4] Breintnell also informed Collinson that Bartram would be “a very proper person” to furnish him with actual seeds and plants from North America. “Being a native of Pensilvania with a numerous Family,” Breitnall observed, “The profits ariseing from Gathering Seeds would enable him to support it.”[5] With that, Bartram and Collinson embarked on a 35-year exchange of botanical materials that forever altered the vegetation of Britain and America.[6]

Collinson coached Bartram in practical techniques for collecting and preserving plants, insects, and animals, while also fostering his knowledge of botany. Early in 1735 he requested that Bartram ship duplicate specimens so that he could “gett them named by our most knowing Botanists and return them again — which will improve thee more than Books.”[7] In May 1737 Collinson returned 208 specimens to Bartram, with identifications made by Johann Jacob Dillenius (1684-1747), curator of the Oxford University Botanic Garden.[8] Working through Collinson's connections, Bartram began supplying plants, seeds, roots, and tubers to eminent members of the European scientific community, including Sir Hans Sloane (1660-1753), president of the Royal Society and patron of the Chelsea Physic Garden in London; Philip Miller, director of the Chelsea Physic Garden; and Carolus Linnaeus, professor of medicine and botany at Uppsala University in Sweden.[9] He also filled requests from wealthy estate owners keen to ornament their gardens with fashionable American trees and shrubs. Among Bartram's most generous clients was Collinson's great friend Robert James Petre, 8th Baron Petre (1713-1742), who preserved some of Bartram's specimens in an herbarium.[10] As demand grew, Bartram began to standardize his practice, assembling boxes containing 100 specimens, mostly of trees and shrubs, that were distributed to British subscribers recruited by Collinson.[11]

The seeds and plants Bartram received in exchange for those he supplied contributed to his creation of botanic gardens of encyclopedic range. A drawing made by Bartram or his son William in 1758 (evidently for Peter Collinson) provides insights into the layout of the gardens, though scant information about their contents. The drawing shows a fenced enclosure containing a "Common Flower Garden" and a "new flower garden" adjacent to Bartram's freestanding "Study" [Fig. 1]. The drawing also shows a small kitchen garden at the back of the main house, connected by a flight of steps to a larger kitchen garden. A pond near the center of the lower kitchen garden conveyed water to the spring or milk house at the far edge of the property. At the opposite side, two tree-lined walks led 150 yards down a moderate slope to the river's edge.

Bartram expanded his knowledge of botany by carrying out plant dissections and experiments with the aid of magnifying lenses he devised in consultation with his Philadelphia neighbor James Logan, an authority on optics.[12] Tinkering with artificial pollination in 1739 at the request of "some ingenious botanists in Leyden," Bartram obtained "curious mixed colours in flowers never known before," which he considered "A gate into A very bare field of experimental knowledge which if Judiciously improved may be A Considerable Addition to ye beauty of ye florists gardens."[13] Bartram yearned to create in Philadelphia an association of "ingenious & Curious men" to share knowledge of the "natural secrets arts & scyences."[14] At his prompting, Benjamin Franklin circulated a proposal that led to the establishment in 1743 of the American Philosophical Society, loosely modeled on the Royal Society in England.[15] Bartram’s correspondents often sent him books, enabling him to further his education while building a valuable natural history reference library. For his services to Dillenius, he received the first volume of Phillip Miller's Gardener's Dictionary in 1737, with the supplement arriving two years later, the gift of Lord Petre.[16] Bartram entered into a more complicated arrangement with the English botanist Mark Catesby, whose magisterial two-volume Natural History contained several Bartram-supplied plants from Peter Collinson's garden. Beginning in 1740, Catesby sent annual installments of his book to Bartram in exchange for American plants — several of which then appeared in the final supplement to the Natural History.[17] In 1745 Collinson's campaigning on Bartram's behalf resulted in the naming of a genera of mosses "Bartramia" by an international group of naturalists led by Linnaeus.[18]

Bartram traveled up and down the East Coast virtually every year from 1735 through 1766, gathering unusual plants and touring gardens from New England to Florida.[19] Attention to the natural habitats of plants shaped Bartram's understanding of botany and his approach to the botanic garden and nursery he was developing at his Schuylkill River farm.[20] Equipped by Collinson with a detailed itinerary, pocket magnifying glass, and letters of introduction, he trekked through Maryland and Virginia in the autumn of 1738, where he was disappointed to find the gardens "poorly furnished with Curiosities." Even those of the wealthy planter William Byrd and the botanist John Clayton lacked the variety of Philadelphia's gardens, enriched by importations from England, France, Holland, and Germany.[21] Bartram frequently visited New Jersey and New York, and while exploring the Catskill mountains in 1842, he made the first of several visits to the Irish-born physician and botanist Cadwallader Colden and his daughter Jane, with whom he carried on a lengthy correspondence.[22] In the spring of 1754, they introduced him to Dr. Alexander Garden of Charleston, who rejoined Bartram in Philadelphia a few months later, spending several days exploring the surrounding countryside in his company.[23] Bartram returned Garden's visit in 1760 on his first trip to the Carolinas.[24] Dr. Samuel Green, whom Bartram met in Wilmington, disappointed him by failing to send promised specimens,[25] but he was delighted by the acquaintances he made in Charleston. Elizabeth and Thomas Lamboll became reliable correspondents and suppliers of tropical specimens,[26] and a brief encounter with the Charleston horticulturalist Martha Daniell Logan, author of the Gardeners Kalender, initiated a mutually beneficial exchange of seeds, roots, and bulbs.[27] Bartram reported to his cousin Humphry Marshall in September 1760, "My garden now makes A glorious appearance with ye virginia & Carolina flowers."[28]

In the 1750s and '60s Bartram's commercial business faced competition from James Alexander, Thomas Penn's gardener at neighboring Springettsbury. Bartram and Collinson kept close tabs on the rare and unusual plants —"fine Ornaments in a Flower Garden"— that Alexander sent to England. [29] Collinson sought to boost Bartram’s business by repeatedly publishing his seed catalogue in The Gentleman’s Magazine in London during the 1750s, touting it as “the largest Collection that has ever before been imported into this Kingdom.”[30] In addition to supplying North American seeds and live plants to correspondents in England, France, Denmark, Germany, Sweden, and Scotland, Bartram was also meeting a burgeoning market in the American colonies for exotic specimens from around the globe.[31] By the 1760s he was wearying of the seemingly insatiable demand for novel curiosities. He complained to Collinson in 1761: “Do they think I can make new ones[?] I have sent them seeds of almost every tree & shrub from Nova scotia to Carolina very few is wanting & from ye sea across ye continent to ye lakes & if I die A martyr to Botany Gods will be done.”[32] Nevertheless, he continued to take on important new clients. In 1764 Bartram began collecting seeds for a new botanic garden in Edinburgh at the request of Dr. John Hope (1725-1786), King's Botanist for Scotland and professor of botany at the University of Edinburgh (view text)— a venture that resulted in Bartram's receiving a gold medal for meritorious service in 1772.[33]

Many seeds and specimens gathered by Bartram found their way to the royal gardens at Kew, and in September 1764 Bartram assembled a box of "new discovered specimens" of plants for George III.[34] The king retained Bartram's services the following April at an annual stipend of £50, with the expectation that he would explore Britain's new Florida provinces and report back to London — an arrangement that owed much to the lobbying efforts of Collinson and Franklin.[35] The king's offer trumped that of Lord Adam Gordon, who simultaneously offered to fund Bartram on expeditions to Quebec and Pensacola, where he hoped to invest in land.[36] Bartram fulfilled his royal commission in February 1766, having spent eight weeks exploring the St. John's River in Florida with his son William. Bartram's report was published in the second edition of Dr. William Stork's A Description of East-Florida, with a Journal Kept by John Bartram of Philadelphia, Botanist to His Majesty for the Floridas; upon A Journey from St. Augustine up the River to St. John's as far as the Lakes (1766). Bartram's expedition to Florida was his last, and he retired in 1771, leaving his nursery business to be carried on by his sons John and Bartram.


  • Bartram, John, May 1738, letter to Peter Collinson, describing sloe trees near Philadelphia (1992): 89)[37]
"The first I observed sloe trees was at a plantation whose owner came two years into this country before A house was builded in Philadelphia[.] I saw another tree near Philadelphia as thick as my thigh & last year I showed James Logan English thorns, Bullises & sloes growing in A hedge which he rides close by from his house to town which I believe hath been planted 20 years."

“Col Byrd is very prodigal in Gates roads walks hedges & seeders [cedars] trimed finely & A little green house with 2 or 3 [orange] trees . . .”

"Mr. John Bartram is an Englishman, who lives in the country about four miles from Philadelphia. He has acquired a great knowledge of natural philosophy and history, and seems to be born with a peculiar genius for these sciences.... He has in several successive years made frequent excursions into different distant parts of North America, with an intention of gathering all sorts of plants which are scarce and little known. Those which he found he has planted in his own botanical garden, and likewise sent over their seeds or fresh roots to England. We owe to him the knowledge of many scarce plants, which he first found, and which were never known before."

"I have met wt very Little new in the Botanic way unless Your acquaintance Bartram, who is what he is & whose acquaintance alone makes amends for other disappointments in that way.... One Day he Dragged me out of town & Entertain'd me so agreably with some Elevated Botanicall thoughts, on oaks, Firns, Rocks & c that I forgot I was hungry till we Landed in his house about four Miles from Town....

"His garden is a perfect portraiture of himself, here you meet wt a row of rare plants almost covered over wt weeds, here with a Beautiful Shrub, even Luxuriant Amongst Briars, and in another corner an Elegant & Lofty tree lost in common thicket — on our way from town to his house he carried me to severall rocks & Dens where he shewed me some of his rare plants, which he had brought from the Mountains &c. In a word he disdains to have a garden less than Pensylvania [sic] & Every den is an Arbour, Every run of water, a Canal, & every small level Spot a Parterre, where he nurses up some of his Idol Flowers & cultivates his darling productions. He had many plants whose names he did not know, most or all of which I had seen & knew them — On the other hand he had several I had not seen & some I never heard of."

“Dear friend, I am going to build a greenhouse. Stone is got; and hope as soon as harvest is over to begin to build it, to put some pretty flowering winter shrubs, and plants for winter’s diversion; not to be crowded with orange trees, or those natural to the Torrid Zone, but such as will do, being protected from frost.”

  • Bartram, John, November 8, 1761, letter to Peter Collinson, contrasting American wilderness with English gardens (1992: 538) [37]
"My correspondents near London writes to me as freely for ye Carolina plants as if they thought I could get them as easy as they do ye plants in ye European gardens that is to walk at their leisure along ye alleys & dig what they please out of ye beds, without ye danger of life and limb."

  • Bartram, John, December 3, 1762, letter to Peter Collinson, describing Charleston, S.C. (1992: 579) [37]
“I can’t find, in our country, that south walls are much protection against our cold, for if we cover so close as to keep out the frost, they are suffocated.”

“The great reputation which you have just acquired, by many faithful and accurate observations, and that most extraordinary thirst of knowledge which has distinguished you, makes me extremely desirous of your correspondence.

“If you will be so kind as send me a few seeds of your new discovered plants, I shall on my part make a return of whatever is in my power, that I shall judge agreeable to you.

“It will be agreeable to you to hear that Mr. Samuel Bard, son of your friend Mr. Bard, of New York, is making most wonderful progress in Botany, and has made a beautiful collection of near four hundred Scots plants; by which he undoubtedly will gain the annual premium.”

  • Bartram, John, October 4, 1764, letter to Dr. John Hope (1849: 433-34)[40]
"I have received your proposals by the hands of our dear friend Benjamin [Franklin]; and since, by a letter from the worthy, humane Dr. [John] Bard, or New York, in which he inserts a paragraph of a letter from his son (whose person and activity I am not a stranger to), wherein he writes to the same effect as thee wrote to Benjamin Franklin, signifying that you had laid a new botanic garden to be stored with exotics; that you were forming a laudable and very necessary plan of storing your bare country with variety of forest trees; that many gentlemen of rank and fortune had countenanced this scheme with an annual subscription, to enable a botanist to make your desired collections; and that my answer was desired, whether I would undertake to supply your demands, which I consent to do, if your generosity is equal to them; for the charges of collecting rare vegetables are in proportion to the distance from home, and hazards and dangers in collecting them….

"I have now sent, as a present, for thy curious amusement, one hundred specimens, some rare, with my remarks upon them, and to your new garden a parcel of curious seeds, near one hundred and fifty different species; and our friend, Benjamin Franklin, engaged me to send you a box of forest trees and shrubs, in which I am going to pack above one hundred different kinds, and send them in the next ship for London."

"Let us... pay a visit to Mr. John Bertram [sic], the first botanist, in this new hemisphere.... It is to this simple man that America is indebted for several useful discoveries, and the knowledge of many new plants....

"Every disposition of the fields, fences, and trees, seemed to bear the marks of perfect order and regularity, which in rural affairs, always indicate a prosperous industry...

"From his study we went into the garden, which contained a great variety of curious plants and shrubs; some grew in a green-house, over the door of which were written these lines,

" Slave to no sect, who takes no private road,
" But looks through nature, up to nature's God!"

"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."

“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.”
