Jefferson documented

This choice native shrub was in cultivation in America and Europe by the 1730's. Many native American plants and seeds were sent to Peter Collinson in England by naturalist John Bartram, Sr. during the mid-eighteenth century, including Mountain Laurel, Sweetpepper Bush, and Carolina Allspice. In 1786, Thomas Jefferson included Clethra in a list of plants to be sent to him in Paris by John Bartram, Jr. for the purpose of introducing American native plants into the gardens of France. Jefferson considered it a good plant for shrubberies and was planting Sweetpepper Bush at Monticello as early as 1771.
