Not Blue, but Green Is the Sky
My rings tell such a story
Of years past with gracious glory
Where I live is where I stay
From that spot I cannot stray
From my home man taketh me

These things that crawl and things that glide
I weep with beauty or stand with grace
Every year I shed myself to nourish my place
What am I?
