Just because summer is ending does not mean that it has to be the end of color in your home landscape. Several herbaceous annuals and perennials come into their full glory in the fall. The old faithfuls for fall color are chrysanthemums (mums) and pansies. These colorful plants provide instant beautification. Mums are usually handled as annuals and are removed in the spring because many do not get established enough to survive the winter. Pansies, when planted in the fall, will become established and survive the winter to bloom again in early spring. Pansies are normally removed when they begin to decline in the early summer heat.
