Chat with our AI personalities
Biennial weeds are plants that complete their life cycle in two years. Examples of biennial weeds include common mullein (Verbascum thapsus), bull thistle (Cirsium vulgare), and garlic mustard (Alliaria petiolata). These weeds germinate and grow in the first year, then flower, set seed, and die in the second year. Proper identification and management of biennial weeds are essential in controlling their spread in agricultural and natural areas.
