Biennial plant

A biennial plant is a flowering plant that takes two years, generally in a temperate climate, to complete its biological life cycle. In the first year, the plant undergoes primary growth, in which its leaves, stems, and roots (vegetative structures) develop. Usually, the stem of the plant remains short and the leaves are low to the ground, forming a rosette. After the first year, the plant enters a period of dormancy for the colder months. Many biennials require a cold treatment, or vernalization, before they will flower. During the next spring or summer, the stem of the biennial plant elongates greatly, or "bolts". The plant then flowers, producing fruits and seeds before it finally dies. There are far fewer biennials than either perennial plants or annual plants.
