With oval, pointed, deciduous leaves and an oval, open canopy, Chinese tallow tree creates soft, dappled shade. The trunk normally dominates, snaking up through the crown sporting major limbs well-spaced along the trunk. Enough light will penetrate to allow lawn grasses to thrive beneath this rapidly-growing, 20- to 50-foot-tall tree. Yellow, terminal flower spikes appear in spring and are followed by brown capsules which burst and fall off, leaving behind wax-coated, white, berrylike seeds, hence the common name, popcorn tree. These berries persist throughout the winter, even after the fluttering, heart-shaped leaves have turned gorgeous autumn shades of reddish purple and have fallen. Tallow tree is one of the only reliable fall coloring trees for USDA hardiness zones 8b and 9a. The new growth in spring is red-tinged. The waxy coating on the seeds is extracted by the Chinese for use in candles and soap and the milky sap inside the twigs is poisonous.

Chinese tallow tree is easily grown in full sun on a wide range of soils and is particularly drought-resistant and tolerant of compacted and wet soil. The abundant seeds create a multitude of unwanted volunteer seedlings. Roots tend to grow quite large near the soil surface and can be a nuisance in the lawn. There are places in Florida and in the Houston, Texas area where the tree has escaped cultivation and is invading native woodlands and the edge of wetlands. Therefore, use of this tree is not recommended! The wood is brittle and small to medium-sized branches often split from the tree as it grows to 15 years old.
Propagation is by seed or cuttings.
No pests or diseases of major concern.
