The poem
The odor from the flower is gone Which like thy kisses breathed on me; The color from the flower is flown Which glowed of thee and only thee!
A shrivelled, lifeless, vacant form, It lies on my abandoned breast; And mocks the heart, which yet is warm, With cold and silent rest.
I weep--my tears revive it not; I sigh--it breathes no more on me: Its mute and uncomplaining lot Is such as mine should be.

Isn't it called on a FADED violet?
Yes Juja, the title of the peom is indeed called On a Faded Violet. The poem is symbolizing a faded flower to a beloved one who is now gone. Shelley is cheerless since the loved one is gone and comparing it to a dead flower.
