Deciduous trees start their growth with a burst of new leaves or flowers in early spring, then remain in leaf through summer. In autumn, the leaves drop to reveal the bare limbs. In many sorts of deciduous trees, the leaves change color before they fall.

If you're choosing a tree primarily for its beautiful flowers, however, you may be willing to wait a number of years for the tree to mature and begin blooming. It's important to visualize the ultimate height and spread of any tree you consider.
