Ambrosia artemisiifolia
Also called Roman wormwood, Ragweed, Short Ragweed, Common Ragweed, Bitterweed, Hogweed, Low Ragweed
Annual ragweed is a fast-growing, much-branched weed native to the Americas and best known as a major hay fever allergen. It is grown as a wild plant rather than a garden plant, and it spreads easily from seed.
Ambrosia artemisiifolia, with the common names common ragweed, annual ragweed, and low ragweed, is a species of the genus Ambrosia native to regions of the Americas.
The plant is native to: North America across Canada, the eastern and central United States, the Great Plains, and in Alaska; the Caribbean on Cuba, Hispaniola, and Jamaica; and South America in the southern bioregion (Argentina, Chile, Paraguay, Uruguay), the western bioregion (Bolivia, Peru), and Brazil. The distribution of common ragweed in Europe is expected to expand northwards in the future due to climate change.
