A biennial plant is a flowering plant that takes two years to complete its biological lifecycle. In the first year, the plant grows leaves, stems, and roots (vegetative structures), then it enters a period of dormancy over the colder months. There are far fewer biennials than either perennial plants or annual plants.Also asked, do biennial plants come back?
Biennial plants grow leaves, stems and roots the first year, then go dormant for the winter. In the second year the plant will flower and produce seeds before dying. They may perform like perennials in the garden because new plants that emerge from seed constantly replace plants that have died after their second year.

Annuals live just one year from seed to death, biennials live two, usually not flowering until the second and perennials come back year after year. Annual plants live only for that year. A perennial is the original plant which returns to flower every year. A biennial is similar but only flowers every other year.
