Jefferson documented

Late seventeenth-century naturalist, John Banister collected this plant in Virginia and sent dried specimens to England in 1688. He later introduced it into the gardens at Fulham in 1690. It was identified then as Spiraea opulifolia, and known commonly as "Trifoliate Virginia Meadow-sweet." Virginia-born aristocrat William Byrd II wrote of the curative properties of Indian Physic, or "Ipecacuaha," to his colleague Sir Hans Sloane of England's Royal Society during the early 1700s. Jefferson listed this choice, long-lived native perennial as a medicinal plant in his only published book, Notes on the State of Virginia. It is known also as Bowman's Root. zone4,zone5,zone6,zone7,zone8
