The establishment had attained such public importance that when the British took possession of Flushing, August 29, 1776, after their victory at the battle of Long Island, the commanding officer, General Howe, placed a guard over the nursery to protect it from depredations, and this was continued until all danger was past.
The extent of the business, as well as the paralyzing effect of the war, is shown from an advertisement of Mr.Prince, shortly after the British occupation, offering 30,000 young cherry trees for sale as hoop-poles, the only use to which they could be put during the Revolution. The loss of domestic business was largely compensated by the great demand for American native trees and shrubs wanted by the officers of the British army to be sent to friends in England and Germany. (!!E.C.)
(In 1789 the place was visited by General Washington, who had long heard of its beauties, but what he saw did not answer his "expectations," for at that time the business was just beginning to recover. http://dunhamwilcox.net/ny/flushing_ny_hist.htm)
A return of peace brought with it increased trade, to make good the depredations of the soldiery as well as to re-stock the orchards of those who for seven years past had paid more attention to the science of war than to the pursuits of horticulture; and a catalogue of 1794, still preserved, contains fully as many varieties of fruit as those of some nurseries of the year 1900, over a century later; apricots and nectarines, for instance, each being represented by ten varieties.
Not only was everything of merit imported, but the origination of new varieties by a careful selection of seedlings was enthusiastically carried on. Two plums, still well known, date from this period, Prince's Yellow Gage being originated in 1783 and the Imperial Gage in 1794. The "Treatise on Horticulture" mentions that in 1790 no less than twenty-five quarts of green gage pits were planted, from which seedlings were obtained of every color and shape, it being probable that the Washington plum was originated in that year.
(Gages are named after Sir William Gage, an Englishman who popularized one of these varieties in England in the 18th century. Gages were subsequently introduced to the USA in the late 18th century.)
Before the death of this William Prince, the nursery business had been taken up by his sons, William and Benjamin; the former on new ground, called the Linnean Botanic Garden and Nursery, and the latter at the original place, called "The Old American Nursery."
William Prince, third proprietor of the Prince Nurseries at Flushing, was born Nov. 10, 1706; married Mary Stratton, Dec. 24, 1794, and died April 9, 1842. During his lifetime the Prince Nursery was one of the centers of horticultural and botanic interest in America, and reached the height of its fame. He continued the work of his father in the introduction of all foreign trees and plants of value, the discovery of unknown American species and the creation of new varieties from seed. One of the trees introduced to great popularity in the younger days of William Prince the second was the Lombardy poplar, of which he advertised in 1798 no less than 10,000 trees 10-17 ft. in height. For several years the Lombardy poplar was the fashionable shade tree. Long avenues of them were planted by the wealthy; and their leaves were considered valuable for fodder. In 1806 the tide turned, owing to a belief that they harbored a poisonous worm, and thousands were cut down and burned.
In 1793 William Prince bought from Bayard, LeRoy and Clarkson, the property on the north side of Bridge street in Flushing, across from the old nursery, containing eighty acres, and it was soon transformed Into a place of arboreal beauty. For fully fifty years the nursery was carried on much less for profit than from a love of horticulture and botany. It was designed to contain every known kind of tree, shrub, vino and plant known to England or America that possessed any horticultural merit. In Europe probably the only one of the same character was that of the London Horticultural Society.
When the great Northwest was explored by Lewis and Clark, many of the botanical treasures found a home at the Flushing Nurseries. Among them the Mahonia became very popular, the earlier specimens being sold at $20 each.
(The genus name Mahonia honors the Philadelphia horticulturist Bernard McMahon who introduced the plant from materials collected by the Lewis and Clark Expedition.)
The catalogues from 1815 to 1850 ranked among the standard horticultural publications of the country. The number of varieties of fruits cultivated seems scarcely credible in these days, when many nurseries are conducted solely for profit, and only the trees or plants which find a ready sale are propagated. The collection of roses at one time embraced over 800 kinds; of dahlias over 350 varieties; the collections of camellias, of citrous fruits and of grapes were enormous, while the marvelous variety of the ordinary fruits can be seen from the "Pomological Manual."
The "Treatise on Horticulture" mentions that at that time (1828) the nursery contained more than 20,000 plums, of 140 varieties, while the apricots numbered 35 and the grapes about 240 varieties. The catalogue of 1845, which enumerates only the best varieties, contains 350 kinds of apples. 300" of pears, 120 of cherries, 200 of plums and 160 of peaches.
In 1828 Mr. Prince wrote and published the "Treatise on Horticulture," which was the first work of the kind produced in America. Mr. Prince was a man of great energy of purpose, of excellent judgment, with a love for scientific studies, and possessed of a most amiable character. By indefatigable effort he succeeded in having roads and bridges built which shortened the distance to New York fully one-half, and soon after the invention of steamboats he had a regular line of boats established between Flushing and New York. He was a zealous churchman, a vestryman of St. George's church, Flushing, as early as 1798, and continued in the vestry 32 years, during 14 of which he was warden. In the words of Mandeville's History of Flushing, he was "universally esteemed in life and regretted in death."
