Many of the most popular trees for gardeners are also some of the fastest growers. Red Maples and Weeping Willows are sold bare-root, about two or three years old, and not more than a few feet tall. But, often, after being planted in your yard, they will grow 3 to 5 feet in one year. These trees are popular because of their interesting foliage and habit, but, because they offer such quick return on your investment, they have become indispensable in landscape design.
Fruit trees are always popular–but often it takes several years before a tree will produce a substantial amount of fruit. But there are a few fast-growing fruit tree varieties that will allow you to be growing your own fruit within a couple seasons. Dwarf citrus trees are small, and mature very fast, but you can only grow these in containers unless you live in a very warm place. Trees from the genus Prunus, like cherries, apricots, plums, and peaches all grow fairly quickly and, they are so diverse that any gardener will be able to find exactly what they need.
