What are examples of biennial plants?

Biennial plants are those that have a two-year life cycle. In the first year, they typically grow leaves, stems, and roots but do not flower. Then, in the second year, they produce flowers and seeds before dying. The selection that includes mullein, bull thistle, and wild carrot represents typical biennial plants. Mullein, for example, grows as a rosette of leaves in its first year and then sends up a flowering spike in the second year. Bull thistle and wild carrot follow a similar pattern, showcasing the characteristic growth and flowering cycle of biennials. This life cycle is essential for understanding plant classification and management strategies, particularly in the context of pest control and land management on rights-of-way.
