It can happen so slowly we do not pause to notice and tend to take things growing on rocks for granted. Lichens take hold with no need for nourishment. Seeds fall into cracks. Mosses huddle around and move up onto damp places. Blueberries thrive in rocky barrens.
Over time dying biomass builds up in hollows where young trees can take root. And when a storm topples an older tree that managed to grow, its roots may release a number of rocks it once held in intimate embrace.
