Vigna Caracalla – also known as “snailflowers”, or “climbing shell plant”, in Bartram’s Garden, a 45-acre National Historic Landmark in the city of Philadelphia. The plant was introduced into European gardens from its native South America in the eighteenth century. It was listed as part of John Bartram’s (1728-1770) “core collection of plants” and was reportedly a favorite of Thomas Jefferson’s.
“…I, continually impelled by a restless spirit of curiosity, in pursuit of new productions of nature, my chief happiness consisted in tracing and admiring the infinite power, majesty and perfection of the great Almighty Creator...” Wm. Bartram, 1791.
