Ornamental Trees: Extinct and Rediscovered
Ornamental trees are generally grown for their aesthetic appeal, although they may also provide other boons. While most often grown for their flowers or even leaves, some deciduous trees provide a fantastic display in autumn as their leaves change colours.
