Gnaphalium sylvaticum, commonly known as heath cudweed,[1] wood cudweed, golden motherwort, chafeweed, and owl's crown,[2] is a species of plant in the sunflower family. It is widespread across much of Europe.[3] The species was first formally described by Carl Linnaeus in 1753.[4]

It is a perennial herb with short runners.[5]
The plant is 8 to 60 cm tall.[5]
The leaves are lanceolate in shape, pointed, 2 to 8 cm long, with a single vein. They have no hair on top, but are woolly hairy below. The upper leaves become progressively shorter and narrower.[5]
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.[5]
