It was probably sent to mainland Europe in 1500’s. Grown at America’s 1st botanic garden, Elgin Botanic Garden 1811. Tradescantia was cherished by the Dakota Indians for its beauty. Cherokee ate the young greens and prescribed it to cure stomachaches after overeating, female illnesses, cancer, and insect bites. Menominee revived those “defiled by touch of bereaved.” Natives applied a poltice of the leaves topically for insect bites and stings.
