What is a defining feature of biennial plants?

Biennial plants are characterized by their unique life cycle, which spans two growing seasons. In the first year, they typically develop a rosette of leaves close to the ground, which allows them to gather energy and nutrients. This growth is crucial for their survival and development. During the second year, they utilize the stored energy from the previous year to flower, produce seeds, and complete their life cycle. This two-year progression sets biennials apart from annual plants, which complete their life cycle in one growing season, and from perennials, which can live for multiple years and often bloom each season. The formation of rosettes is a definitive characteristic that enables biennial plants to manage their energy reserves efficiently.
