Perennial plants have indefinite lifecycles, based on the species.

What is the difference between annual flowers and perennial flowers?

Plants can be classified as either annual, biennial, or perennial. Annual plants complete their lifecycle in one growing season, during which they produce seeds, then die. Common annual plants include impatiens, zinnias, and sunflowers. Biennial plants, such as some types of foxglove, live for two growing seasons before setting seed and dying. The term perennial is reserved for plants that live for more than two years.

Trees and shrubs live for more than two years. Are they perennials?

Technically speaking, trees and shrubs are perennial plants -- they grow for more than two years. But we categorize perennial plants into two types: woody plants and herbaceous perennials. Woody plants are trees, shrubs, and vines whose above-ground parts persist over the winter, and resume growth in the spring. Herbaceous perennials are non-woody plants that die back to the ground each fall. The roots, however, survive the winter and the plants re-sprout in the spring.

Why grow perennials instead of, say, a bed of annual petunias, marigolds, or impatiens?

If you grow lots of annual flowers, you are familiar with the annual chores necessary to maintain such beds: you purchase flower seedlings (or start your own), and plant them. You nurture them throughout the growing season, fertilize and water them; then, when the season's over and the plants die, you pull them out. Next year, the cycle begins anew.

Perennial plants remain in the ground year after year. Once established, many perennials need minimal upkeep in the form of watering and fertilizing, since their roots are more far-ranging than annual plants’ roots. Many perennials spread readily, filling out garden spaces and providing more and more color each year.

Now that you're sold on adding perennials to your flower beds, stop in and see all the perennials we have for you.
