Pierre Jardin named one side of the Petriverse “Woodstone Forest,” because it features compositions combining rock and wood. Petrification of wood takes ages, but Pierre designed a work to investigate wood and stone turning into one another on a shorter term schedule. In the lovely pine tree that shelters Pierre’s home and shades the garden’s south slope, he ‘planted’ stones in forked branches two years ago, and since then gravity has pulled the stones to earth while the branches continue to grow upwards. These organic forces have made an amalgam where rock grows into wood; it is impossible to remove the rocks from the tree, leaving the tree a bit vulnerable or fearful feeling, if not fully petrified. The rocks look at home in the tree, and the tree becomes something more from the presence of the rocks. The juxtaposition of rock and wood and growth of them into a single entity expresses the ongoing biological and geological transformations that unfold in time alongside the time of our lives.
