DistributionOccurs throughout the state, and presumably is found in all 100 counties.

This is a wide-ranging species of the eastern US. It ranges from southern Canada to the Gulf Coast but is not widespread in the Great Lakes states.
AbundanceCommon to very common across the state, except only fairly common to common in the mountains.
HabitatThis is a species of sunny, dry habitats. It grows in abandoned fields, roadsides, woodland borders, rock outcrops, and powerline clearings; it is likely the most often seen member of the genus in the state.
PhenologyBlooms from July to October, and fruits shortly thereafter.
IdentificationThis is a small and quite slender herbaceous species growing only to an average of 9-12 inches high, with many upright branches. All of the branches are green, and as the leaves are very short, scale-like and appressed to the stems, the whole plant looks like a bunch of leafless green twigs angled sharply upward. The small yellow flowers occur singly along the stem and at the tips of the stems. As this is such a common and widespread species, most observers should be able to find this species easily and recognize this slender plant quickly at a single glance.
Taxonomic CommentsNone

Other Common Name(s)Orange-grass, Orange-grass Pineweed, Gentian-leaved St. John’s-wort. Though Pineweed is colloquial and provides no indication of genetic relationship, this has been the most widely used common name in field guides and most references for decades. A number of websites now use Orange-grass as the common name or as part of the common name.
