Description
editDespite its common name, the plant is not a grass. It is a rhizomatous perennial herb growing up to 80 centimeters tall with green or brown stems covered in silvery hairs. The leaves are grasslike, linear to lance-shaped with silvery hairs. The inflorescence contains a few to over a hundred flower heads which contain yellow ray and disc florets. This species can be quite variable and some authors divide it into several varieties.[2]
This plant is used as an ornamental and for vegetating roadsides and other disturbed habitat. It can be used in xeriscaping. It can help control erosion. It can reproduce by seed and it can form large colonies by spreading via its rhizomes.[3]
It is found in dry or sandy soil and pine barrens. It grows from July to September.[4]
