Sub-category: Aster family
This plant is a subshrub or shrub with erect stems up to 3.5 meters tall. The leaves are lance-shaped or somewhat oval and have toothed edges. They are variable in size, measuring from 3 to 12 centimeters or more in length. The inflorescence is an elongated array of many small flower heads with whitish florets.
This plant is very common in salt marsh habitat throughout its native range. While it is tolerant of salinity, it is not very tolerant of flooding, so it tends to grow in a narrow band along the upper margins of marshes. The band may be just a few meters wide, and individuals nearest the water may be stunted.
