The reddish leaves of maples, the height of pines, and the chipped bark of ancient olive trees are some of the features that ultimately make trees unique. Even so, the sheer number of trees and aspects to be evaluated makes it difficult to single out a single tree as the most beautiful. But in 2011, the Environmental Partnership Association (EPA) launched an annual collaborative competition to find the most beautiful tree in Europe. After the voting period closed, the trees selected for their beauty and history were revealed this Wednesday.
