Another piece of the eternal mystery, life’s need to make more life. From the animal world to the plant: Milkweed trees sent their seeds aloft on the wind, to grow far from home; pinecones flared open at their mother’s feet, a skirt of stubby seedlings scrabbling for space and light. Succulents would grow anew from a broken-off leaf, pushing roots out into the air, then down into the soil: a piece of its own body, transformed into its child.
