Analysis of I am a Sunflower

Out here in the field,
roses and dandelions are all you can see-
Captivated by the sunbeams,
I caught you by my shining gleam.
I'm never the favorite,
nor the one you'll always pick-
But the sunrays have made my petals sleek.
I am bright and strong,
for I capture all the sun has in store.
I will live carefree as can be,
just how like the sun mold me.
To spread vibrance and joy,
while depending on no one but me.
