It is a perennial herb with short runners, growing to 8 to 60cm tall. Its leaves are lanceolate in shape, pointed, 2 to 8cm long, with a single vein. They have no hair on top, but are woolly hairy below. The upper leaves become progressively shorter and narrower. The flower heads are 6mm long. The bracts of the flower heads have a green centre, and chaffy brown edges. The florets are pale brown. The achenes are hairy with reddish pappus hairs. It flowers from July until September.[7]
