Also known as Japanese Meadowsweet, this ornamental shrub was first introduced from Asia around 1870 to 1880 due to its showy flowers. Its rapid spread when it escapes from cultivation crowds out native species in natural areas. It is now classified as invasive in the Mid-Atlantic states, including Virginia, and is on the list for Arlington County.
