How long do biennials grow, and what do they do each year?

Biennials typically have a two-year lifecycle, which distinguishes them from annuals and perennials. During the first year, biennials primarily focus on vegetative growth. They develop a root system and often form a rosette of leaves close to the ground. This rosette stage is crucial as it allows the plant to store energy and nutrients.

In the second year, biennials enter the flowering stage. They use the energy accumulated during the first year to produce flowers and ultimately set seed. This two-year cycle ensures that the plants have adequate resources for successful reproduction.

Choosing the correct answer reflects an understanding of this growth pattern and the sequential activities of biennials.
