I come in a cup but also from the mouth I hang from a tree but in me some sing I am thoughts given life but I am also alive what am I?

I cover your plants and window surfaces I take, but I'm also something you can do to a cake

I wear a little green cap, but have no head, my freckles bloom, speckling the red. I’m sweet but shy in summer’s sun, and am nestled low when day is done.

I shine in skies both calm and clear, And judge without a bias near. I charm the eye with beauty rare, Where laughter spins through open air.

My heart is stone Yet I’m a treat My form a derriere Enjoy my meat
