Take a look at this tree, the Osage Orange, otherwise known as the Maclura pomifera. This tree is known for its dense growth and thorny bark. When grown in a line, they can be used to create a sort of "living fence". Its large, light green fruits, often referred to as "monkey brains", are a valuable source of food for various animals, including white-tailed deer, squirrels, and small rodents. The tree's leaves are sharp and ovular, and its mature bark develops thick, twisting brown ridges.
