What is the significance of the title to the last part of the selection of "Rose of Emily"?William Faulkner's "A Rose for Emily"

Since the rose of the title is symbolic, the reader must
search for the meaning of this symbol. Interestingly, William Faulkner does not indicate
the color of the rose for Emily.  Therefore, the rose can have a number of meanings. 
Traditionally, of course, red roses symbolize love and passion; however, other colors
suggest innocence and truth (white), friendship and freedom (yellow), and desire
(coral), and grace, gentleness, and joy (rose).  The single rose conveys the meaning of
"I love you."

That Faulkner leaves the meaning of "A Rose
for Emily" rather ambiguous, the reader must look to the text for meanings.  In one
passage, for instance, the narrator suggests Emily's innocence in believing that she
need pay no taxes:

Only a man of Colonel Sartoris' generatin and
thought could have invent it, and only a woman could have believed
it.

In Part II of the story,
the reader learns that Emily Grierson has been deserted by her sweetheart.  Here the
passion of Emily, the red rose of her life, has left, and the townspeople remember "all
the young men her father had driven away."  Then, after her father dies, the townspeople
feel that Emily has become humanized in her freedom from her
patriarchal domination as

...she too would know the old thrill and the old
despair of a penny more or less. (yellow
rose)

However, with the
appearance of Homer Barron, Emily's passion seems to have been rekindled.  But, when he
departs, she is not seen on the streets for some time.  The narrator comments
that 

 Then we
knew that this was to be expected, too; as if that quality of her father which had
thwarted her woman's life so many times had been too virulent and too furious to die.
(coral rose)

In Part V, after
Emily dies, the authorities break down the door of Emily's home and amid the "thin,
acrid pall of the tomb," they find a room furnished for a bride with curtains of "faded
rose color" (pink), and they discover the body of Homer Barron lying on the bed in this
room of faded rose.

Thus, William Faulkner's title, "A Rose
for Emily," through the narrative, comes to symbolize the life of Emily, innocent,
passionate, briefly free and joyous, and faded.  In a telling passage the narrator
declares,

We
remembered all the young men her father had driven away, and we knew that with nothing
left, she would have to cling to that which had robbed her, as people
will.

Therefore, in the final
part of Faulkner's story, Emily clings to the single rose--"I love you"--in the form of
the man who is the last would not marry her, Homer Barron.  The title, "A Rose for
Emily" with relation to the final part symbolizes Emily's desperate attempt to hold all
from which she has been robbed: desire, passion, joy, and love.
