English Quaker merchant Peter Collinson (January 28, 1694–August 11, 1768) traded seeds and plants with colleagues across the Atlantic Ocean, especially John Bartram of Philadelphia. Collinson is credited with introducing at least 150 species, mostly from British North America, to English gardens during the 18th century.
Peter Collinson was a passionate amateur gardener and significant importer of American exotics into England throughout the middle of the 18th century [Fig. 1]. Although he never traveled to North America, he maintained an active correspondence with American colonists and traded seeds and plants with associates across the Atlantic Ocean for more than three decades. In addition, Collinson played an important role in supporting the nascent Library Company of Philadelphia and bolstering the scientific experiments of Benjamin Franklin (1706–1790).
Collinson was born to Peter Collinson, a Quaker cloth merchant from London, and his wife, Elizabeth Hall, in 1694. He received his “first Likeing to Gardens & plants” at his grandmother’s in Peckham, Surrey, and noted in a memorandum he wrote later in life her preference for formal topiary, such as “Clip’d Yews in shapes of Birds, Dogs, Men & Ships &c.” Collinson’s curiosity in natural history was, according to Jean O’Neill and Elizabeth P. McLean, also fostered by Quaker beliefs that encouraged gardening as a way to connect with God. As a Quaker, Collinson was not permitted to attend an English university, and his knowledge of botany and natural history was likely largely self-taught, using the collection of natural history books he had amassed for his personal library. In 1711 Collinson began working for his father, selling high-quality fabrics in England and the British colonies, and, about a decade later, he and his brother James took over the family import and export business. Collinson gained a reputation as an able and dedicated naturalist, and, in 1728, under the sponsorship of Sir Hans Sloane (1660–1753), he was elected to the Royal Society.
Through the Royal Society as well as his professional involvement with transatlantic trade, Collinson developed an extensive network of contacts in British North America and particularly among the Quaker community of Philadelphia. Collinson knew Thomas Penn (1702–1775), the son of Pennsylvania’s founder William Penn (1645–1718), who moved to Pennsylvania in 1732 and resided at Springettsbury, his seat on the Schuylkill River. During the nine years that Penn lived there, Collinson acted as his agent in London and provided Penn with plants he imported for his estate, including grapevines, horse chestnuts, cornelian cherries, Syringos, pyracantha, phillyrea, and long-blowing honeysuckle. Collinson also sent Penn prints of English country seats, books, and packages of seeds. Collinson corresponded with prominent Philadelphians Joseph Breintnall (d. 1746), the first Secretary of the Library Company of Philadelphia, and the physician Dr. Samuel Chew (1693–1744). By 1732 Collinson was helping the Library Company build its collection (view text). Through the Library Company, Collinson became acquainted with Benjamin Franklin, and, in 1745, Collinson sent Franklin publications on electricity to aid in his research. In 1751 Collinson published Franklin’s Experiments and Observations on Electricity.
Collinson’s greatest interest was plants, and he developed gardens first at his home in Peckham and later at Mill Hill, located about ten miles northwest of London. In 1721 he wrote to George Robins (1697–1742) of Maryland, “Forget not Mee & My Garden,” hoping, perhaps, that Robins would send plants from North America (view text). Two years later, he received seeds and plants from his cousin, Richard Hall, of Maryland, who sent Collinson Senna marilandica and a tulip tree, among other specimens. Upon visiting Collinson’s garden in Peckham, Pehr Kalm (1716–1779), the Swedish botanist and student of Carl Linnaeus (1707–1778), described how Collinson used horses’ knucklebones to edge the borders and remarked that it was “a beautiful little garden, full of all kinds of the rarest plants, especially American ones” (view text).
Collinson’s garden became even more ambitious in 1749, when Collinson and his family moved from their home in Peckham to Ridgeway House in Mill Hill. Although his wife inherited the house upon the death of her father, Collinson had begun cultivating plants at the garden at Mill Hill years earlier. His garden was better known for the variety of specimens he collected than for its overall design. While botanic artists such as Georg Dionysius Ehret (1708–1770), George Edwards (1694–1773), and Mark Catesby (1683–1749) illustrated individual plants from Collinson’s garden, there is no known depiction of the garden itself. Collinson’s collection of lilies and orchids was particularly noteworthy. He raised exotics in a forty-two-foot-long greenhouse and wrote about his delight at being able to “smell the sweets of so many odoriferous plants,” even when his garden was snow-covered (view text). His collection was targeted by thieves, and Collinson lamented in 1762 that “twenty-two different species of my most rare & beautifull plants” had been stolen from his garden (view text).
Collinson made his greatest impact on botanical and horticultural history as an importer of plants from North America. Although Collinson claimed to make no profit from these activities, he was, according to Alan W. Armstrong, “a demanding collector who badgered his ship-captain friends and commercial contacts (especially in Quaker Philadelphia) for specimens and good local collectors.” The Philadelphia botanist and horticulturalist John Bartram (1699–1777) was Collinson’s most important and prolific supplier of North American plants, and the two men exchanged plants and seeds for more than three decades. This network of exchange helped supply the period fashion for American plants in English gardens. Mark Laird has argued that “Through regular consignments of more than one hundred woody species, Bartram and Collinson effectively afforested English shires with Pennsylvanian wilderness.”
Though they never met in person, their letters evidence a strong friendship grounded in a “shared love of gardening and a fanatical desire for new plants.” Collinson began corresponding with Bartram in 1733, and the following year Bartram sent Collinson his first shipment of plants from North America. By January 1735 he had begun to pay Bartram for this kind of work. Collinson wrote that he “employed Him [Bartram] to Collect Seeds, 100 species in a box at five guineas Each from the year 1735 to this year 1760 about 20 boxes a Year.” Collinson served as the middleman, selling the plants that he obtained from Bartram to various botanists, gardeners, and nurserymen throughout England and Europe; he also kept some specimens, including mountain magnolia (Magnolia acuminata), “sarsifrax” [sassafras], rhododendrons, kalmias, and azaleas, for his own garden at Mill Hill.
Their most significant—and first—patron was Robert James (1713–1742), the eighth Baron Petre, of Thorndon Hall in Essex. Collinson arranged for Bartram to send Lord Petre two boxes of North American tree seeds—including several species of hickory, white and black walnut trees, sassafras, dogwood, red cedar, sweet gum, swamp laurel (magnolia), spruce (hemlock), chestnut oak, white oak, swamp Spanish oak, and tulip tree—in the fall of 1735. Several years later, Collinson wrote to Bartram of Lord Petre’s gardens that “when I walk amongst them, One cannot well help thinking He is in North American thickets—there are such Quantities” (view text). Lord Petre also desired live animals from North America for his estate, and Bartram sent terrapins and turtles to stock the ponds at Thorndon Hall. According to Collinson’s records, Bartram also sent boxes to Edward Howard (1686–1777), the ninth Duke of Norfolk (and Lord Petre’s cousin), at Worksop Manor; Charles Lennox (1701–1750), the second Duke of Richmond, at Goodwood; John Russell (1710–1771), the fourth Duke of Bedford, at Woburn; Archibald Campbell (1682–1761), the third Duke of Argyll, at Whitton; John Stuart (1713–1792), the third Earl of Bute; Norborne Berkeley (d. 1770), Lord Botetourt at Stoke Park; and Charles Hamilton (1704–1786) at Painshill Park, among many other patrons.
Scholars have argued that the collaboration between Collinson and Bartram bolstered both men’s reputations. Bartram probably would not have secured the financial support needed to undertake the collecting expeditions that made him “the preeminent American naturalist of his time.” Collinson also provided Bartram with exotics that he could not easily obtain otherwise (view text). Collinson is credited with introducing at least 150 new species from British North America to Europe—many of which were provided by Bartram. Without Bartram's plants, Collinson likely would have been remembered as “a minor figure in the history of the Royal Society,” according to Armstrong. Indeed, it was one of Bartram's plants that ensured Collinson’s legacy: it was only after Linnaeus named a species native to eastern North America after Collinson in 1737—a specimen of which Collinson sent to Linnaeus for study—that the naturalist felt his contributions to the field had been adequately honored. He thanked the Swedish botanist for naming the plant Collinsonia canadensis and thus “giving Mee a species of Eternity (Botanically speaking) . . . a name as long as Men and Books Endure” () [Fig. 2].

- “A good situation is a very essential point to be considered in the choice of a vineyard a gentle declivity to the south is esteemed the best, which more speedily carries off the water, which on a flat is apt to stay long, & is very prejudicial, a sandy gravelly dry soil is best. Juices produced from this, is stronger & better flavoured, than from a low moist situation.
- “A good shelter is very necessary & should be raised on all sides but the south by raising plantations of trees of the quickest growth as hickory locust, &c. but on that side which is most exposed to the strongest winds the plantation must be made more formidable but let none be planted so near the vines as to drip upon them.”

- "I wish att a proper season Thee would procure a strong box 2 feet square and about 15 or 18 inches deep but a foot Deep in Mould will be enough. Then collect half a dozen Laurels and half a Dozen shrub Honeysuckles [azaleas] and plant in this Box, but be sure to make the bottome of the Box full of large Holes and cover the Holes with Tiles or oyster shells to Lett the Water draine better off. Then Lett this box stand in a proper place in thy Garden for two or three years till the plants have taken good Root and made Good Shoots. But thee must be Care full to water it in Dry Weather."

- “ . . . takeing the following Methode I have raised a great many pretty plants out of your Earth. I lay out a Bed 5 or 6 feet long, 3 foot Wide. Then I pare off the Earth and Inch or Two Deep, then I Loosen the bottome and Lay it very smooth again and thereon (if I may use the Term) I sow the Sand & Seed together as thin as I can. Then I sift some good Earth over it about half an Inch thick. This bed ought to be In Some place that It may not be Disturbed & kept very Clear from Weeds for several seeds come up not til the second year."

- Kalm, Pehr, September 1748, describing Peter Collinson’s garden at Peckham (quoted in Brett-James 1926: 30–31)
- “June 10, in the afternoon, I went to Peckham, a pretty village which lies 3 miles from London in Surrey, where Mr. Peter Collinson has a beautiful little garden, full of all kinds of the rarest plants, especially American ones, which can endure the English climate and stand out the whole winter. However neat and small it is there is scarcely a garden where so many kinds of trees and plants, especially the rarest, are to be found. Peter Collinson uses knucklebones for his borders and he explained to me his method of sowing mistletoe and also experiments he had made with cranberries. He thinks it is best for a garden to have the morning sun so that it may help to dry up the vapours. Quadrilateral is the best shape and is the one which he has adopted, whereas the gardens of the Duke of Richmond are round. The sun is not so effective. He told me also of the use of meadowland in Middlesex, north of Hamptstead. The people do not use the plough but keep horses and hardly any cattle. The manure thus obtained is sent to London frequently. I saw a tree clipped to form the roof of a summer-house and also a chestnut cut so as to make a shelter over a bench.” back up to History
