Biennial plants or flowers take two years to complete their lifecycle. These take two seasons to produce seeds and then die. During the first season, the plant will produce foliage, and in the second season, it will flower and produce seeds.
Some outlive the second season and continue flowering making people confuse them for perennials. However, these don’t live as long as perennials do. Biennials are great as decorative plants and herbs. They will colour your garden for the next two years.
