What is the difference between annuals and perennial? The short answer is that annuals don’t come back, but perennials do.
Perennials are plants that can survive in the garden for at least two growing seasons. They die back in the winter and then, as if by magic, they return lush and renewed, ready for another go at life. These plants manage to survive because their roots can weather the winter climate in their growing zones. A garden filled with perennial plants is a lot less work than one that’s mostly annuals. While there’s still work to be done in a perennial garden—pruning and weeding, for example—there’s no need to replant everything each year.
The secret to a stunning perennial garden is to choose varieties that bloom at different times, which ensures that your yard will pop with color in different season.
While annuals live for only one season, they tend to have a long bloom season. They are usually bright and showy, used by gardeners to add burst of bright color to their flower beds and container gardens. A good example of an annual flower are chrysanthemums.
