Introduction
Chinaberry is a round, deciduous, shade tree, reaching 30 to 40 feet at maturity and growing 5 to 10 feet during the first and second year after seed germination. Growth slows as the tree reaches 15 or 20 feet tall. It is successfully grown in a wide variety of situations, including alkaline soil where other trees might fail. Truly an urban survivor, chinaberry has become naturalized in much of the South.

Use and Management
The clusters of lilac flowers are fragrant in the evening but are often hidden by the emerging foliage. The leaves turn a vivid yellow for a short time in the fall. The golden yellow fruit is quite attractive as it persists on the tree during the fall and winter. When eaten in quantities, the fruit is poisonous to people but not to birds. The wood is very brittle but it has been used in cabinet making.
Chinaberry is considered a "weed" tree in the southeastern U.S., and so it is not usually available from nurseries. It is killed back to the ground in the northern end of its range and is often seen as a several-year-old sprout. Many people despise the tree because it has taken over waste areas and other disturbed soil areas, and has naturalized over large areas of the South. It grows anywhere in any soil except wet soil. But with proper pruning to create a well-formed trunk and branch structure, the plant could improve its reputation. If you have one and would like to increase its life-span, prune to open up the crown to encourage development of a few well-spaced major limbs. You will not find anyone recommending planting this tree but fine examples of the tree can be found growing in the worst soil.
The cultivar 'Umbracultiformis' has a dome-like form and could be the plant seen commonly in some wild stands. It is often sold as Texas Umbrella-Tree. It would be nice to find a fruitless selection.
Propagation is from seed or root cuttings.
Pests and Diseases
Scale, whitefly and sooty mold infest chinaberry.
Leaf spot causes premature defoliation.
