What does a biennial weed do?

Explanation:
A biennial weed has a two-year life cycle. In the first year it grows leaves and stores energy, often forming a rosette, and overwinters. In the second year it grows again, produces flowers and seeds, and then dies after seed production, typically by the following winter. So it seeds during the second year (usually in the second summer) and dies in winter. This distinguishes biennials from annuals (which complete their life cycle in one year) and from perennials (which live for many years).
