A garden full of flower plants of different types is more beautiful to see. More so if the garden contains a mix of annual flower plants along with others. Annual flower plants are those which exist for only one complete season. This means their complete life cycle from germination from seeds to death occurs in a lifespan of only a few months. The positive thing about annual flower plants is that they give flowers generously during their blooming periods. And this blooming period also exists for a comparatively longer time than other flower plants.

Annual plants are divided into three types based on their hardiness. Hardiness is the measure of intensity of cold weather or frost that the plants can endure. Apart from staying alive, the plants grow and bloom during this period effectively. There are mainly three annual periods - warm weather annuals, cool weather annuals, and frost hardy annuals.

Annual flower plants must be planted specifically in the season during which they can complete their whole life cycle successfully. Plants that are capable of growing in one season will certainly die off if planted in some other season because the intensity of cold will vary from one region to another.

There are two main conditions to be met here. Firstly, the annuals must be capable of growing in the soil found in that particular area. Secondly, they must be grown only in that particular season in which they can thrive.

Warm weather annuals include zinnias, marigolds, and nasturtiums. These plants are incapable of tolerating any plants. Hence, these can be planted in any region containing the soil needed for these plants during the summer season.

Cool weather annuals are snapdragons, petunias, and calceolaria. These plants thrive during the end of summer and at the start of early frost.

Frost hardy annuals are pansy, stock, calendula, and larkspur. These annuals plants can take quite a lot of frost and still blossom during the season. These are usually planted at the end of mild winter and before the beginning of deep winter.

You can find out what annual plants the soil in your area would support from a number of websites on the internet. This information can also be found in a number of books relating to horticulture. Apart from all this, if you have a plant nursery close to your house, just visit it and find out which annuals will survive in which season in your area.
