Daffodil leaves are flat and broad to cylindrical at the base and arise from the bulb.
The emerging plant generally has two leaves, but the mature plant usually three, rarely four, and they are covered with a cutin containing cuticle, giving them a waxy appearance.
Leaf color is light green to blue-green. In the mature plant the leaves extend higher than the flower stem, but in some species, the leaves are low hanging.
The leaf base is encased in a colorless sheath. After flowering, the leaves turn yellow and die back once the seed pod (fruit) is ripe.(source)
