Some examples are corn, beans, marigolds and zinnias. Biennials are plants that complete these life cycle in two years or two growing seasons. The first year, these plants will have roots, stems and leaves. The second year, they will grow flowers and form fruit and seeds. The plant will die after the second year.
Some examples are beets, strawberries and hollyhocks.
The third group of plants is called perennials. Perennials live more than two years before their life cycle is complete. At the end of each growing season, a part of the plant will remain alive in a bulb or in the roots. The leaves and stems will die on some plants, on other plants even the stems will remain. Some examples are tulips, daisies, lilies and trees.
