Seaside goldenrod is a native perennial plant with large, golden yellow flower clusters that bloom in late summer and autumn.
Seaside goldenrod consists of large clusters of tiny, golden yellow flowers at the top of a tall stem. Flower clusters are upright or slightly drooping and bloom in August to October. Long, waxy, evergreen leaves are arranged alternately along the stem, getting bigger toward the bottom of the stem. Seaside goldenrod grows 3 to 6 feet tall.
Seaside goldenrod grows in high parts and along the edges of fresh, brackish and salt marshes. It is found in parts of the marsh that are irregularly flooded by tides, and also grows on beaches and sand dunes in coastal areas. It can grow in full or partial sun.
Grows in the southern half of the Chesapeake Bay watershed, including Delaware, Maryland and Virginia.
After blooming, flower clusters mature into seed heads filled with fuzzy, nut-like fruit capsules that each contain one seed. Wind spreads the seeds.
