About

Iva frutescens is a species of flowering plant in the family Asteraceae known by the common names Jesuit's bark, bigleaf marsh-elder, and high-tide bush. It grows in coastal eastern North America from Nova Scotia down the eastern coast and along the Gulf Coast to Texas.

Iva frutescens is a subshrub or shrub with erect stems up to 3.5 meters (almost 12 feet) tall. The leaves are lance-shaped or somewhat oval and have toothed edges. They are variable in size, measuring from 3 to 12 centimeters (1.2-5.0 inches) or more in length. The adaxial (upper) side of the leaf is often covered is small warts, helping to distinguish it from sympatric shrubs. The inflorescence is an elongated array of many small flower heads with whitish florets.
