Triadica sebifera

Triadica sebifera (syn. Sapium sebiferum), the Chinese tallow, Chinese tallowtree, Florida aspen, chicken tree, gray popcorn tree, or candleberry tree, is a tree native to eastern Asia. It is native to eastern China, and Taiwan, and introduced to Japan in Edo period. The waxy coating of the seeds is used for candle and soap making, and the leaves are used as herbal medicine to treat boils. The plant sap and leaves are reputed to be toxic, and decaying leaves from the plant are toxic to other species of plants. The specific epithets sebifera and sebiferum mean 'wax-bearing' and refer to the tallow that coats the seeds. It is useful in the production of biodiesel because it is the third most productive vegetable oil producing crop in the world, after algae and oil palm. This species is documented as a noxious invader in the southern U.S. The simple, deciduous leaves of this tree are alternate, broad rhombic to ovate in shape and have smooth edges, heart shaped and sometimes with an extended tail often resembling the bo tree, Ficus religiosa. The leaves are bright green in color and slightly paler underneath. They become bright yellows, oranges, purples and reds in the autumn. The tree is monoecious, producing male and female flowers on the same plant. The waxy green leaves set off the clusters of greenish-yellow and white flowers at bloom time. The flowers occur in terminal spike-like inflorescences up to 20 cm long. Light green in color, these flowers are very conspicuous in the spring. Each pistillate (female) flower is solitary and has a three-lobed ovary, three styles, and no petals. They are located on short branches at the base of the spike. The staminate (male) flowers occur in clusters at the upper nodes of the inflorescence. Fruits are three-lobed, three-valved capsules. As the capsules mature, their color changes from green to a brown-black. The capsule walls fall away and release three globose seeds with a white, tallow-containing covering. Seeds usually hang on the plants for several weeks. In North America, the flowers typically mature from April to June and the fruit ripens from September to October. Triadica sebifera is native to China, and Taiwan, and introduced to Japan during Edo period. It is also found in the southeastern United States, Puerto Rico, Costa Rica, Taiwan, India, Martinique, Sudan, and southern France. Incorrectly thought to have been introduced in colonial times by Benjamin Franklin, the tree has become naturalized from North Carolina southward along the Atlantic and the entire Gulf coast, where it grows profusely along ditchbanks and dikes. It grows especially well in open fields and abandoned farmland coastal prairie regions featuring disturbed ground—such as abandoned farmland, spoil banks, roadsides, and storm-damaged forests—and along the edges of the Western Gulf coastal grasslands biome, sometimes forming monoculturess.
