- Description
-
Seaside Goldenrod, is an herbaceous perennial wildflower often found on beaches, dunes, salt marshes, and pinelands. This plant is highly salt tolerant and deer resistant. The plant produces basal leaves topped by 2 to 8 foot stalks. The terminal or upper axillary flowering heads are dense, the lowest branches somewhat recurved. Arching branches bear one-sided clusters of large, bright yellow flower heads. Pinch the growing tips in June for a more compact plant. This goldenrod does not spread by rhizomes or become invasive.
Goldenrods have been wrongfully accused of causing hay fever which is actually an allergic reaction to wind-borne pollen from ragweed. The Goldenrod genus contains about 120 species, most with similar characteristics. The Seaside Goldenrod may get confused with one of its cousins. This plant is deer resistant.
This plant can be used in the back of the border in poor sandy soils. Do not fertilize this goldenrod.
Habitat: Coastal dunes, dune slacks, maritime wet grasslands, tidal marshes
Insects, Diseases, and Other Plant Problems: No serious insect or disease problems. Rust, powdery mildew, and leaf spot may occur.
