This "Mammoth" Chrysanthemum has semi-double lavender flowers with yellow centers. Mature plants form large mounds up to 91 centimetres tall and over a metre wide. These hardy mums have been selected for their hardiness, vigour and mammoth size from the University of Minnesota. These mums take several years to reach their mature height and form.
Grow Mammoth Mums in average well drained soil in full sun to light shade. They do not require pinching, pruning or deadheading. If desired they can be pinched in June to keep the plant more compact. They will take at least two seasons to reach their mature height and width. A mulch to conserve moisture and prevent the hot sun from baking the roots of the plants is highly recommended
