Solidago nemoralis is a species of flowering plant in the family Asteraceae. It is native to North America, where it is widely found in Canada (every province except Newfoundland and Labrador) and the United States (all states wholly or partially east of the Rocky Mountains).[3] Its common names include gray goldenrod,[4]gray-stem goldenrod, old-field goldenrod,[5]field goldenrod,[1]prairie goldenrod, dwarf goldenrod,[6] and dyersweed goldenrod.[7]
Description
Like other goldenrods, this species is a perennial herb. One of the smaller goldenrods, it grows 20 centimeters to one meter (8–40 inches) tall from a branching underground caudex.[6] There are 1 to 6 erect stems, sometimes more.[8] The stems are reddish to gray-green and have lines of short, white hairs.[6] The lower leaves are up to 10 centimeters (4 inches long) and the blades are borne on winged petioles. Leaves on the upper half of the stem are narrower and shorter and lack petioles. The spreading inflorescence can carry up to 300 flower heads. The head contains 5 to 11 yellow ray florets each a few millimeters long surrounding up to 10 yellow disc florets. Flowering occurs in late summer and fall.[8] The fruit is a rough-texured cypsela about 2 millimeters long tipped with a pappus of bristles slightly longer.[8]

Ecology
This plant grows in forests, woods, prairies, grasslands, and disturbed areas such as old fields and roadsides.[8] It is a pioneer species and it can become weedy.[6]
