Garden mums (Dendranthema morifolium) give us a burst of color in the fall when used to replace the annuals we have enjoyed since spring. Mums provide color until freezing weather arrives.

Mums grow between 1½ to 3 feet tall depending on cultivar, growing conditions and whether they are pinched regularly during the growing season.

Growth Rate

Garden mums are hardy perennials throughout South Carolina, although many people treat them as short-season, fall-planted annuals. Chrysanthemums grown as perennials will spread rapidly. They should be divided every year or two.

Ornamental Features

Garden chrysanthemums are valued for their intense color display at the end of the growing season. Flowers are available in many forms and colors range from pure white to yellow, bronze, pink and lavender, coral and salmon, purple, and deep burgundy red.

Disease problems can include powdery mildew, Botrytis blight, aster yellows, leaf spots, viruses and foliar nematodes. Insects that commonly infest chrysanthemums are aphids, thrips and spider mites. For information on chrysanthemum pests and diseases consult HGIC 2101, Chrysanthemum Diseases & Insect Pests.

Landscape Use

Chrysanthemums prefer fertile, highly organic, well-drained soil in full sun. Mature plants set in a shady area will give nice color the first year but do very poorly the following year.

The right amount of water is vital to success with chrysanthemums. Too little water will slow their growth or stop it completely. Mums especially need plenty of water when they bloom. Give plenty of water to field-grown mums to prevent wilting until they re-establish a good root system.

Mums are heavy feeders. A weekly application of soluble fertilizer is a good practice. Mulch will help retain soil moisture, control weeds and improve appearance.

Chrysanthemums can be planted in the fall or in early spring. Spring planted mums will give a more robust, full plant for the fall landscape. Pinch the tip growth of spring-planted mums regularly to cause them to branch and bloom well. Remove the top ½ to 1 inch of new growth about every four weeks from the time the plant is 6 inches tall until early July in the upper piedmont and mountains, up to early August at the coast.


Chrysanthemums are classified according to shape and arrangement of petals. The major types of hardy mums include the following.

  • Daisies or Singles have daisy-like flowers with yellow centers.
  • Anemones are like single mums but with a rounded crest of deeper color.
  • Decoratives have double or semi-double flowers and usually grow to over 18 inches tall.
  • Pomponshave small ball-shaped flowers, on plants that are usually under 18 inches tall.
  • Cushion mums are not a flower form but a name used for early-flowering, low, bushy mums.

These are just a few of the many cultivars available:
