Cultivars listed in the table below have been developed based on years of plant breeding at the University of Minnesota. These plants have been selected for superior flower characteristics, growth habit, and winter hardiness. Most will survive winters in Minnesota. Florists mums, sold throughout the year in supermarkets and greenhouses, may not survive Minnesota winters, and if they do, will probably not flower before hard frosts. Division Plants can be dug and divided in spring as new growth begins.
Stronger shoots are usually on the outside of the clump.
Set the growing tip of each division just below ground level. For an attractive display or color, plant at least three shoots in a triangular pattern. Florist Mums Attractive blooming potted plants are available throughout the year from florists. After flowers fade, plants can be cut back to 3 or 4 inches and planted in the garden. Florists mums may over winter, but usually flower too late for USDA Zone 4.
