But once all is done, the fruits of your labor are well-paid off by the beautiful blossoms and delicious vegetables. Following is some information along with a list of these beautiful biennials.

Information and Characteristics of Biennial Plants
Biennials refer to the plant's longevity. They take two years to complete their life cycle. A biennial plant's life cycle begins as seeds which later produces the roots, stems, and leaves.

In the first season, their growth results in a small rosette of leaves close to the soil. The next year, i.e., during their second season, they begin to grow, flower, and seed, which is soon followed by the death of the entire plant.

During the long growth period of the plant, it prepares itself to grow and bloom as it conserves its energy to develop complex flower structures, produces a large amount of seeds, and becomes mowing and/or grazing resistant. Below are some characteristics of biyearly plants.

✿ Biennials have a late season growth at ground level and they continue to grow even in spring.
✿ They bloom in the late spring and summer and sport beautiful flowers on tall spikes.
✿ They have significant seed production, and their seedlings emerge again between late summer and fall.
