Jefferson is not known to have grown Rose Mallow at Monticello. However, in his Notes on the State of Virginia, he does include "Syrian mallow Hibiscus moschentos" among the state's medicinal plants that "would principally attract notice." It is an herbaceous perennial that is native to low, marshy sites in eastern North America. John Bartram sent seeds to England in the mid-1700s, and it was recommended for American gardens by Bernard McMahon in 1806.
