Bartram's Garden is the oldest surviving botanic garden in North America. Located on the west bank of the Schuylkill River, it covers and includes an historic botanical garden and arboretum (, established circa 1728). The garden is near the intersection of 54th Street and Lindbergh Boulevard, in Philadelphia. Special events at the Garden include an annual spring plant sale, Mother's Day festivities, and a holiday gifts & greens sale. The John Bowman Bartram Special Collections Library contains a vast collection of documents and materials related to the history of the Garden, as well the history of Philadelphia and the development of the field of botany. The non-profit John Bartram Association operates the Garden in cooperation with the Philadelphia Department of Parks & Recreation. ==The garden== Located on the western bank of the Schuylkill River, the garden is on the site of the farm owned by American botanist John Bartram. Bartram, a Quaker, built the original stone house between 1728–31. He later expanded it, adding a kitchen around 1740 and a Palladian-inspired, carved facade between 1758-70. The house still stands, as does his original garden (circa 1728) and greenhouse (1760). Three generations of the Bartram family continued the garden as the premier collection of North American plant species in the world. The current collection contains a wide variety of native and exotic species of herbaceous and woody plants. Most were listed in the Bartrams' 1783 broadside ''Catalogue of American Trees, Shrubs and Herbacious Plants'' and subsequent editions. The garden also contains three notable trees: * ''Franklinia alatamaha'': John and William Bartram discovered a small grove of this tree in October 1765 while camping by Georgia's Altamaha River. William eventually brought seeds to the garden, where they were planted in 1777. The species, named in honor of John Bartram's friend, Benjamin Franklin, was last seen in the wild in 1803. All Franklinia growing today are descended from those propagated and distributed by the Bartrams, who are credited with saving it from extinction. * ''Cladrastis kentukea'': A notably old tree, possibly collected by French plant explorer André Michaux in Tennessee and sent to William Bartram in the 1790s. * ''Ginkgo biloba'': This male ginkgo is believed to be the last of three original ginkgoes introduced to the United States from China, via London, in 1785. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bartram's Garden」の詳細全文を読む スポンサード リンク
