Answer: Flowers can be annual, perennial or biennial. Annual plants grow, blossom, and set seed in one growing season. Perennial plants grow, blossom and set seed in one growing season, then die back - to return again next year. Perennials live three or more years. Biennial plants grow green tops the first year and blossom the second year. The blooms will set seeds and the plants will die. Some perennials will not bloom until they're mature, sometimes in the second year after starting from seed. But, most will bloom the first year. If you have a mixture of seeds, you'll get many blooms this summer and some plants will show up again next year.
