That Olde Chestnut

I am a chestnut tree Hard to crack! “That olde chestnut.” The hurricane barks! My leaves are green With enormous veins: Lizard's claws; Grip tight their victims. Upon my bough A patchwork nest: A golden ratio nestled In the centre; Bustling with baby sparrows Mama sparrow is picking The warms Loitering in the undergrowth. I am a chestnut tree In the autumn; My fruit brown Harvested. And burst open. I am a chestnut tree Who swing and sway! My roots are steely And fallen leaves are hay. I am a chestnut tree; A reliable witness to many Centuries old stories! Danny old boy carved a Bleeding heart On my bough. His bestowed's name is Mary She is fair and ninety! I am a chestnut tree In a London park. I stand tall and mighty And am proud! My heart is a sapling; Bearing young loves!
