Peggy Cornett at Thomas Jefferson's Monticello tells us that
In July 1791 Thomas Jefferson ordered three each of ten varieties of roses from the William Prince Nursery on Long Island, NY. In November of that year William Prince sent two each of the roses including Cinnamon Rose, Rosa cinnamomea. This spring flowering species has reddish-brown, cinnamon-colored stems and fragrant, pale pink, semi-double flowers.
