Gustaaf A. van der Hoeven Kimberly Williams Perennial flowers have become more popular in recent years because of a demand for flowers that do not have to be replanted each year. Perennials may grow for many years, depending upon the species. Although the foliage dies during the winter, the roots remain alive to produce a new plant that flowers next year.
Biennials require two growing seasons to complete their life cycle.
During the first year they are vegetative, often having a rosette growth habit. The second season the plants produce flowers, set seed and die. This text was extracted from the publication, MF-707.
