Captive Grace

My many petals are among my greatest qualities.
They're pink, rare and bloom all year round.
My stems are long, and I have two,
Unlike other flowers.

I can float peacefully upon water,
Which many do not know.
My friends and I swarm the fields,
With our bright vivid colors.

We all look alike,
Though I know I am special,
With my yellow spheres,
That resemble the sun.

You humans pick me from my home,
And place me in your bouquet,
Only to be looked at once,
Then deserted to rot away.

I am the pink flamingo.
