This species is a clump-former, lacking the rhizomes that make many goldenrod species thuggish aggressors in the garden. It can self-seed prolifically.

Once a coastal species, for the last thirty years it has spread inland along salted roads.

Goldenrods are unjustifiably blamed for pollen allergies caused by other plants, especially ragweed. Goldenrod pollen is heavy and is not airborne.

Plants should be spaced 18" apart---6-9" as suggested above is inadequate

It is hardy in USDA Z3-11.

A handsome looking native perennial that ranges along the Atlantic Coast from southern Florida up to Newfoundland and along the Gulf of Mexico coast from Texas to Florida. It has bluish-green, smooth, hairless, thick leaves and good club-like clusters of yellow flowers in late summer to November. It grows in the sandy soil of the dunes and seaside marshes. North Creek Nursery, a native plant nursery, in southeast PA offers it as a garden perennial for sunny places with well-drained soil.

Will grow in pure sand, common on dunes near ocean beaches (salt tolerant, of course).
