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 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. 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. Pompons have 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. Tracy' is a very late white double daisy with a spreading growth habit. Yellow Sarah' is a late-blooming, yellow quilled decorative.
