Add vibrant late summer and fall color to your flowerbeds with mums. Also called chrysanthemums, mums are an easy-to-grow, low maintenance perennials that provide late season color when many other perennials are done flowering for the season. In the fall, flowers cover the plants creating a vibrant display. For a huge impact, consider our Monster Mums. These sun-loving perennials are so big, they can be used like small shrubs to line a walkway. Mums prefer well-drained soil and a sunny location. They can be planted in partial shade, but perform best with several hours of direct sunlight daily.
