Chinese tallow tree (Triadica sebifera): how to identify it

Flowers, fall color, bark and size

Flowers. In spring, Chinese tallow hangs yellow, drooping, catkin-like spikes up to about 8 inches long (UF/IFAS; NC State). The flowers have no petals; male flowers crowd the upper part of each spike and a few female flowers sit at its base (NC State).

Fall color. The Mississippi State and USGS fact sheet, published by University of Arkansas Extension, describes bright green summer foliage often turning fiery red in fall; NC State lists red, yellow and purple. A roadside tree turning red in a southern wetland, with white seeds appearing as the leaves drop, is a strong Chinese tallow candidate. The trees with red leaves in fall guide covers the native trees that turn red at the same time. The southern tree identification guide covers the native trees it grows among.

Bark. Dark brown to reddish, gnarled and fissured, thickening with age and peeling in narrow vertical strips (NC State).

Size. The Mississippi State and USGS sheet gives 30 to 40 feet, sometimes over 50 feet; UF/IFAS says it commonly grows to 30 feet. In the Southeast it is deciduous, though the same sheet calls it deciduous to evergreen across its range.

Chinese tallow vs redbud, chinaberry and poplar

Three trees get mistaken for it. The leaf and the fruit separate them; the milky sap and stalk glands confirm Chinese tallow.

Eastern redbud. NC State's redbud profile describes heart-shaped leaves with smooth, entire margins and flat pods about 2 to 4 inches long that may persist through winter. Its leaves are larger than a tallow's 1 to 3 inches, and its fruit is a pod, not a seed cluster. The redbud page covers it in full, and the heart-shaped leaves guide sorts the other trees with heart-shaped leaves.

Chinaberry. Another southern invasive, often searched alongside Chinese tallow. NC State's chinaberry profile describes twice-pinnate leaves 12 to 24 inches long with toothed leaflets up to 2.75 inches, lavender flowers, and wrinkled yellow fruit 0.4 to 0.5 inch that lasts through winter. One look at the leaf settles it: Chinese tallow leaves are single blades, never divided.

Eastern cottonwood. A young cottonwood's triangular leaf can resemble a tallow leaf, but cottonwood leaves have toothed edges and a stalk flattened from side to side (see the poplar page). Chinese tallow leaves have smooth edges, two glands at the top of the stalk, and milky sap.

Where it grows, its status and the never-eat rule

Chinese tallow is native to China, Japan and Korea (Mississippi State and USGS). UF/IFAS says it was introduced before 1800: Benjamin Franklin sent seeds to Georgia in 1772, and André Michaux noted it spreading into coastal forests as early as 1803. It is now naturalized from North Carolina south through central Florida, west into Texas and northwest into Arkansas, and in Florida it is found in almost every county (UF/IFAS). The Mississippi State and USGS sheet notes that it has turned coastal prairies in southern Texas into closed-canopy forest within 10 years, and that a tree produces around 100,000 seeds on average.

Status, attributed to each source:

• Florida: on the Florida Department of Agriculture and Consumer Services Noxious Weed List since 1998, and a Florida Invasive Species Council Category 1 species (UF/IFAS).
• Florida, Louisiana, Mississippi and Texas: listed as a state noxious weed, though not a federal noxious weed (Mississippi State and USGS fact sheet).
• North Carolina: listed as invasive by the NC Invasive Plant Council (NC State), which also lists it as invasive in Florida, Arkansas, California, Oklahoma, Texas and Georgia.

Never eat any part. NC State lists the fruits and leaves as poisonous, with nausea and vomiting as symptoms, and the Mississippi State and USGS sheet says the white fruit is thought to be poisonous. If a person or a pet swallows seeds or leaves, call a poison control center or a veterinarian. For the other invasive trees of the South, see the invasive trees guide.

Using a photo to confirm it

Tree Identifier names a tree from one photo of the whole tree, a leaf, the bark, the flowers or the fruit. For Chinese tallow, photograph a leaf flat with its stalk visible, and in fall a seed cluster; together they rule out redbud and poplar. The app shows no confidence score and no look-alike list, so check its answer against the sap and gland tests above. Its Toxicology tool gives AI-written notes for people, dogs and cats, and the follow-up chat can answer questions such as how to tell tallow from chinaberry. Chinese tallow is not among the 138 species in the app's Collection; save the spot on the Tree Map if you plan to report it to your state's invasive-species program.
