Get a kaleidoscope of late-season color with our Mammoth Mum Collection. It includes seven plants, an assortment of lavender, red, coral, yellow, white and bronze. Our Mammoth Mums are truly perennial mums. Just plant in the spring and allow them to grow—and they'll come back bigger and more beautiful every year. Within three years, you'll have a mounded plant that's 3 ft. tall and 4 ft. across and will be covered in blooms in the fall. No pinching, pruning or deadheading is needed. Bred by the University of Minnesota, Mammoth Mums can withstand sub-zero winter temperatures. Grow Mammoth Mums in perennial flower beds, containers or in a row as a low hedge. They are deer-resistant perennials that attract butterflies. Prefer full sun to partial shade. Zones 4-8.
