What are annual flowers? Annual flowers are plants that germinate from seed, flower, establish seed, and die out usually within one season.
Annual flowers are well known for their flower power or to say it another way, for their quantity of blooms.
Many varieties bloom all season long.
However just as the name implies, annuals thrive for just one growing season.
I believe that they are best used when added to a perennial garden to help keep a riot of color all season.
Hardy annuals can withstand frost. Annuals that are damaged or killed by frost are considered half-hardy annuals.
Because of their brief life span, annual flowers will not interfere with the growth of other plants. They normally have little or no special soil needs, such as soil amendments.
Annuals are excellent in mixed borders especially among perennials, shrubs, and trees.
