There’s something available for any gardener wanting to add vibrant color to their landscape.

What Are Annuals Exactly?

Annuals are a flower or plant that completes their entire growth cycle in one season. They can be seeded, planted, and harvested in the same year. Annuals are the perfect choice for a busy gardener who may not have the time to tend to perennials or shrubs that take multiple seasons to mature.

Whether you’re new to gardening or consider yourself an experienced green thumb, adding annuals will help your garden thrive. They also provide an array of color and texture that adds life to any garden setting throughout all four seasons – even if it’s only temporarily in the case of most annuals. Most importantly, annuals provide a great starting point for novice gardeners as these plants are hardy and have a fast turnaround time.
