Humans, being made in God's image, are able to cooperate in creation much more than other of God's creatures. We do this in many ways, but one way is in shaping plants to suite our purposes. I give the following examples. Sometimes the beauty we are able to create is amazing, as in the rose below (a result of hybridization I am sure). Other times we reshape plants externally to fit our needs (as in the heavily trimmed olive trees seen below). I freely admit that I am not a fan of doing such dastardly things to a beautiful olive tree.
Sometimes human cooperation with God's creation enhances beauty.
