Explain what the dandelion symbolizes to Katniss.

Katniss sees the dandelions as a symbol of hope.

Text evidence;

I had just turned away from Peeta Mellark's bruised face when I saw the dandelion and I knew hope wasn't lost. I plucked it carefully and hurried home. I grabbed a bucket and Prim's hand and headed to the Meadow and yes, it was dotted with the golden-headed weeds. After we'd harvested those, we scrounged along inside the fence for probably a mile until we filled the bucket with the dandelion greens, stems and flowers. (Chapter 4)
