Identifying Characteristics

Size/Form: Chinese tallow is a small deciduous tree that averages from 30' to 50' in height, with a thin canopy that may be rounded or pyramidal. The trunk is often gnarled.
Leaves: The leaves are simple, alternately arranged and broadly ovate or triangular (rhombic). Leaves are 1 ½" to 3" long and have rounded leaf bases with two distinct glands and scale-like bracts where the petioles connect. The leaf tips are acuminate (slightly pointed) and margins are entire. Leaf surfaces are smooth (glabrous) above and below. The medium-green leaves turn bright orange and red in the autumn.
Twigs: Twigs may be either smooth or waxy (glaucous) and often show small brown lenticels.
Bark: The bark is light gray, with vertical fissures and flat ridges. The tree has toxic, milky-white sap.
Flowers: The flowers of Chinese tallow are attractive to bees and other insects and are borne in spikes roughly 8 inches long and appear from April to June. No petals are present but the sepals are yellowish-green.
Fruit: Tallow produces ½" brown capsules that split open to reveal large, white, waxy seeds. These may persist on the tree for several months, hence the nickname of popcorn tree.
