What do you call giant sleeping Lizards?

I wear a coat of emerald green, With tiny veins like rivers seen. I dance with fairies in the breeze, And whisper secrets to the trees. I hold a drop of morning’s dew, A tiny mirror of the sky so blue. When autumn comes, I trade my hue, For amber, gold, and crimson too. What am I, a little spell the forest grew?

I have rings but never marry. I can stand for centuries without moving. Yet when someone mentions me first thing in the morning, they’re rarely talking about nature. What am I?
