What Are Annual Plants?

Annual plants are those that germinate and grow flowers for the ultimate purpose of reproduction. Annual plants only last for one season but have a very season blooming. These plants are normally used and handled by gardeners. Additionally, because of their vibrant color and nature, these are used for decorative purposes as well.

Most of the annual plants will have to be re-planted again. However, a few plants like the forget-me-nots or sweet alyssum will grow on their own. In such cases, there is no need for re-planting.

Examples of hardy annuals are Larkspur and Forget-me-nots.

2. Tender Annuals

Unlike hardy annuals, tender annuals are known to thrive best in warmer climates. Also known as warm-season annuals, the best examples include flowers like petunias, marigolds, etc.

If you live in a warm location and are considering buying these annuals, it is best recommended to purchase them during the end of the spring season. That way, you can get the maximum benefits from these plants.

3. Annuals That Are Half And Half

The only main purpose of annual flowering plants is to germinate and reproduce. To fulfill this purpose, they grow a lot of flowers to help with easy pollination.

Annuals also tend to thrive in warm and cold environments.

The other difference is that perennials are known to thrive well in colder climates.

This is a very interesting variety as they sow their seeds once the second year has passed. Within the following two years, seed formation occurs, and you will notice that your garden has a wide variety of blooms from a new generation.

Biennials are also a little tricky as they require some planning and a whole lot of patience. When this is done properly, you will see the growth of new roots, leaves, and stems in your biennial plant.

Why Should You Purchase Biennial Plants?
