"(...) it was nature herself who created the shapes and patterns (...) without the need for pruning shears; branches feathered down or twisted towards the sun; some trees grew so bushy that they were green barriers, while others were as delicate as ornamental lattice-work against the sky. (...) It was like painting with trees. The different hues of leaves, Miller said, should be like 'Lights and Shades in Pictures', while Collison described the way in which Petre used a tree's foliage, its texture, bark, height and shape, as his 'living pencils'."
