What Is a Biennial Plant: The vast majority of gardeners know the difference between perennial and annual plants. The annuals are those that fulfill their life cycle in a single year and the perennials that produce seeds in each season, but the plant continues to last.
This is not an obstacle, so that in some areas, due to the climate, some perennial plants are treated as if they were annual; that is another song. But what about the biannual plants? What are they?
What is a Biennial Plant
Well, neither more nor less are plants whose life cycle is completed in two years. That is to say that if the plants in summer or autumn of a year will not give you flowers until the following season.
They are plants that simply need more time to flower than annual plants. As in the case of perennials, climate also has great importance. So in cold areas, the biannuals will behave as such, and in warm areas, they can live several years and behave like perennials without winter frosts.
There are not many biennial plants used in gardening, and we would highlight the following: rudbeckia, poppy, California poppy, myosotis or forget-me-not, thought, digitalis, and campanulas, among others. We can find annual, biannual, and perennial varieties within the same species, and we must make sure to buy the seeds.
We will use the biennial flower plants in the same way as the annual ones. In fact, when we acquire them already developed in the nursery, they can flourish in the first year because they will already be grown. They tend to be very attractive and striking, just like the annual flower plants.
Bi-annual plants, like many annuals, can self-replicate with their own seeds, so we will not have to worry for a long time. On the other hand, others are more delicate and can not do it.
In short, a little curiosity to keep in mind so that if we plant some seeds in summer or autumn and we see that they do not bloom in the season, it may be a biannual plant. Always read the information on the seed pack we have bought!
Not only can flowering plants be biannual, but there are also vegetables and greens that are. Although it is a feature that is not usually taken into account. So beet, all types of cabbage, carrots, onions, and parsley are biannual plants. There is already a season in tow in the case of those that we plant by means of bulbs, onions, and others. All these vegetables do not bloom in the year of their sowing, and that is why they are considered biannual.
