Both Perennial flowers and Annual flowers have their own characteristics and advantages. The difference between the both flowers is genetic.
The term “Perennial” refers to herbaceous plants, such as trees, are perennial. Examples of well known perennial flowers comprises of the Tulips, Asters, Susan and Lilies. Perennials can be divided into two categories, The Deciduous Perennials and The Evergreen Perennials.
After remaining quiescent throughout the winter, the Perennial flowers continue to develop year after year. Perennial gardens are replaced often with lively, colorful Annuals. The life of the Perennial plants is for more than two years. They continue growing and return until they reach maturity, which varies by plant but averages three to five years.
Perennials build “structures” such as overwintering buds, bulbs or tubers that contain cells that are not yet specialized and while the next growing season begins, it can be converted into stalks and leaves.
Annuals naturally are planted in the spring and summer months, it blooms for the season, and then dies. Annuals are also commonly used as borders and in containers or in the flower boxes to brighten up the landscape. Most annuals bloom for a long period of time. They provide beautiful colors from spring through fall and are popular with flower gardeners.
They grow as green plants in their first year, survive the in winter and then bloom the following year.
Annuals experience the rapid growth following germination and rapid transition to flower and seed formation, and thus prevents the loss of energy needed to create permanent structures. The most interesting fact is that some plants that are perennials in their local area may be known as the annuals in other area. For example: Snapdragon. These types of plants are sometimes they are known as half-hardy annuals or frost-tender perennials.
