In most of the cases when gardeners talk about plantations they usually speak of perennials or annuals as they are the most popularly known types of plantations among gardeners.
However, there is one another type of plantation called biennial that each and every gardener should be aware of and that is the biennial!
Essential Of A Biennial Plant
Before learning anything further about a biennial plant it is essential to explore its definition and difference from annuals and perennials.
Perennials are those plants which live for more than 2 years and annuals are those plants that have a life of one year or less. On the other hand, biennials are the type of plants that fall into the category between the annuals and the perennials. This means that those plants whose biological life cycle is more than one year but less than or equal to 2 years are known as biennials.
In the initial stages, i.e within the 1-year biennials develop leaves, stems, and roots and then it enters into a dormant phase in the winter season. In the next year, the plant blossoms providing flowers, fruits, and seeds. Some of the most common biennials grown all over the globe are broccoli, parsley, carrot, onions and in the flowers section, we got pansies, alcea, and rudbeckia hirta.
Understanding that a certain plant is a biennial often gets ignored or unnoticed mainly due to lack of knowledge and awareness. In fact, most of the plants bought in nurseries are biennials and in their second growth stage.
However, it is to be well noted that in extreme climatic conditions a biennial may complete its whole biological life cycle of 2 years in a very short time frame say 3 or 6 months. This case is common in vernalized biennial plantations and in reality vernalization is quite essential to flower a biennial plant.
Furthermore, this rapid growth of biennials in extreme climatic conditions is also a major reason for gardeners being unaware of this category.
Rapid advancement in the growth of biennials is quite fascinating and is actually a reaction of the plant to the stimuli it receives from outside. Location plays a big role in this case and if a gardener is growing a biennial in extreme climatic conditions then it is obvious that he will be unaware of the real status of the plant and consider it to be annual unless and until he studies about the nature of the specific plantation.
As compared to annuals and perennials, biennial plantations are quite less in number. From a gardeners perspective, growing biennials has its own benefits and shortcomings. For instance, saving up the seeds of biennials is quite a tough job to crack as it usually takes more than 1 year for it to flower.
Due to this, it is hard for the biennials to survive cold weather conditions unless and until necessary measures are taken to protect the plant.
In order to accomplish this, it is recommended that you cover the plant fairly enough in the winter season or store them elsewhere till hard winter passes.
