What are some possible symbols and the meaning for the title in "A Rose for Emily"?

The unseen rose is one of the dominant symbols of "A Rose
for Emily"--hence the use of the word in the title. It is a symbol of love, beauty and
romance, and represents Emily herself: a fading flower of days gone by. The color of
rose also appears in the final chapter upon the discovery of the valance curtains'
"faded rose colour;" the rose also represents death--the color of blood--as in the
"blood-kin" relatives that appear just before Homer's
disappearance.

Other examples of symbols found in the
story:

• Miss Emily's house serves as a symbol of
  the town's past glories as well as its present state of decay.
  


• Miss Emily's hair serves as a symbol of the passage of
  time, from its girlish shortness, cut following the death of her father, to the
  iron-gray strand that becomes so important in the final
  chapter.
