Omalotheca sylvatica, synonyms including Gnaphalium sylvaticum, is a species of plant in the family Asteraceae.[1] It is commonly known as heath cudweed,[2] wood cudweed, golden motherwort, chafeweed, owl's crown,[3] and woodland arctic cudweed.[4] It is widespread across the temperate Northern Hemisphere, throughout North America and Eurasia.[5] The species was first formally described by Carl Linnaeus in 1753 as Gnaphalium sylvaticum.[6]
Description
It is a perennial herb with short runners, growing to 8 to 60 cm tall. Its 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. The flower heads are 6 mm 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]
