mature and bi

-annual plants Mature and bi-annual plants are those that need to be planted from seed, or from cuttings, every two or more years in order to produce flowers or fruits. These plants are very common, as they often have a longer flowering season, more flowers, and more disease resistance than annuals. Bi-annuals may require a little more effort to maintain, but they will provide beautiful blooms and contentment for many years. These plants may also require periodic trimming as well as regular fertilization to stay healthy and vigorous.
