Strong root systems: The roots are deeper and able to reach nutrients further down in the soil.
They bloom at different times of the year: With planning you can stagger the blooming and have color from early spring until the first frost.
Easy to plant: Perennials are hardy plants that do well in shade and sun and keep coming back year after year. They tend to be smaller in size and multiply filling in bare spots.
Inexpensive: They are a one time purchase. You do not need to purchase more every year like annuals.
Low Maintenance: Once they are planted they need less care. The deep root systems allow them to get the nutrients they need.
Benefit other plants: The deep roots of perennials bring up water and nutrients to the surface for plants with more shallow roots. They also provide ground cover and preserve soil moisture during the colder months.
