Plants that need two seasons to complete their vegetative and reproductive growth are called Biennials.
Biennials are plants that complete their life cycle in two growing seasons. During the first growing season, biennials produce roots, stems and leaves; during the second they produce flowers, fruits and seeds, and then die.
Biennials grown for flowers, fruits or seeds need to be grown for two years. Biennials that are grown for edible leaves or roots are grown for just one year
`Eg: Silverbeet, Black-eyed Susan, Sweet William, colic weed, carrot, etc.
