Each plant has its individual needs and completes its life cycle in its own unique way over a period. It is because of this that you will find some plants take longer to grow and mature, while others take a shorter time to grow, mature and die out. In biology class, we were taught that there are annual, perennial, biennial plants and that each grows in its own unique way and time. Here is a quick look at each.
Perennial plants are those plants that continue to grow for many growing seasons. With these plants, only the top part of the plants dies each winter before growing up again the following spring from the very same root system.
Biennial Plants and Garden
Biennial plants are those plants that require 2-years to complete their life cycles. The first season’s growth results in small rosettes of leaves near the soil’s surface. During the plant’s second season stem, seed and flowering formation starts taking place before the entire plant dies.
Annual plants are those plants whose entire life cycle right from the seed to the flower takes place within one growing season. All the stems, leaves and roots of the plant die off annually. It is only the dormant seeds that bridge the gap between two generations.

If you are still wondering what sort of plants these are, then here is a good example. Have you ever seen those plants that only live for one year before dying? If you have, then those are what’s known as annual garden plants. These plants sprout from their bulb or seeds, grow to maturity, reproduce offspring before dying within the span of one year. Interestingly, there are plants that will do this within as little as one month, while others will take almost one whole year.
Characteristics of Annual Plants & garden flower seeds
Compared to other plants, annuals tend to be a bit showier. It is believed they are so because they need extreme colored foliage and flowers plus fragrant scents to make them more appealing to pollinators. This explains why these plants tend to have sweet smells and multicolored blooms.
Anual plants are typically planted in early spring from whence their cells start to elongate rapidly to ensure that growth is quick. Once the plant reaches full size, hormones like gibberellins and cytokinins take over, causing the plant’s flowers to bud and open. This usually takes place around late spring/early summer. The opening of these plants’ flowers tends to coincide with summer when a majority of pollinators are active. Once pollination takes place, be it by wind, bird or insect, the plant then starts to produce seed.
Chemical changes taking place within the plant as it forms seeds signals it that it has reached the end of its life cycle. This often takes place around late fall/early winter and lead to the dying off of the plant. By doing this, the plant has completed its mission, which is to reproduce and ensuring that its genetic data is not lost for years to come.
