A garden can be full of a variety of annuals and perennials. Annuals are plants that remain in constant bloom usually until the first frost of the year. Perennials, however, return every year from the root. They can bloom at different times throughout a season. To create a beautiful effect in a garden, plant a combination of annuals and perennials. A wide variety of flowers bloom during late summer into autumn.
