Biennial

A biennial plant is a one which takes two years to complete its cycle. In the first year the plant grows leaves, stems, and roots, then it enters a dormant period during the colder months. The stem will generally remain very short and the leaves will be low to the ground, forming a rosette. Many biennials require a cold treatment, or vernalization, before they will flower.

During the next spring or summer the stem of the biennial plant will elongate greatly, or "bolt". The plant will then flower, producing fruits and seeds before it completes its cycle.
