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 considered to be a noxious invader in parts of the southern U.S.Triadica sebifera, also known as Sapium sebiferum, is commonly known as the Chinese tallow,Chinese tallowtree, Florida aspen, chicken tree, gray popcorn tree, and candleberry tree. The tree is native to eastern Asia, and is most commonly associated with eastern China, Taiwan, and Japan. In these regions, 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 plant. The specific epithets sebifera and sebiferum mean "wax-bearing" and refer to the vegetable tallow that coats the seeds.
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.
Although native to China and Japan, the plant is also found where it has been introduced 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 pure stands. In the Houston area, Chinese tallow trees account for a full 23 percent of all trees, more than any other tree species and is the only invasive tree species in the 14 most common species in the area. The Texas Department of Agriculture lists Chinese Tallow as one of the 24 most invasive plants, and includes Chinese Tallow in a list of Noxious and Invasive Plants which are illegal to sell, distribute or import into Texas. Herbivores and insects have a conditioned behavioral avoidance to eating the leaves of Chinese tallow tree, and this, rather than plant toxins, may be a reason for the success of the plant as an invasive.
The plant is sold in nurseries as an ornamental tree. It is not choosy about soil types or drainage, but will not grow in deep shade. It commonly grows all over Japan, and is reasonably hardy. It is prized for its abundant and often spectacular autumn foliage.
The tree is common in southeast Oklahoma as well, although it is not depicted on the map.
The seed's white waxy aril is used in soap making. The seed's inner oil is toxic but has industrial applications.
The nectar is non-toxic, and it has become a major honey plant for beekeepers. The honey is of high quality, and is produced copiously during the month of June, on the Gulf Coast. In the Gulf coast states, beekeepers migrate with their honey bees to good tallow locations near the sea.
The tree is highly ornamental, fast growing and a good shade tree. It is especially noteworthy if grown in areas that have strong seasonal temperature ranges with the leaves becoming a multitude of colours rivaling maples in the autumn.
The tree grows well in urban areas, and is very good for "sidewalk holes" along busy roads with a lot of traffic where most trees will not grow well. It can provide shade to counter the heat island effect of mainly-concrete areas, as well as habitat for urban animals such as lizards and birds.
As aforementioned, the tallow tree is a non-native species to many places around the world. Its introduced status in North America along with the harm it causes to ecosystems makes the tree considered an invasive species there. Tallow trees present a danger of expansion that can hurt local ecosystems by out-competing native vegetation and creating a monoculture. The monoculture would then lower the species diversity and overall resilience of the area. The tree-s tenacious nature, high growth rates, and high reproductive ability contribute to its invasive success. According to the U.S. Department of Agriculture, tallow trees begin producing viable seed in as soon as three years. They can spread by root sprouts and cuttings and are quick to invade after a disturbance occurs in an area, due to the clearing out of land. A single tallow tree can produce nearly 100,000 viable seeds annually that can remain in the soil for several years before sprouting. A mature stand can produce 4,500 kilograms of seeds per hectare per year. These seeds are easily carried to different places by birds and water. Tallow trees can remain productive for 100 years. It is also extremely hard to kill-its poisonous features in its leaves and berries leave it with few to no predators, and its short generation time means even freshly cut trees can quickly regrow. Currently, herbicides and prescribed fire are the only effective treatments available to contain and control Chinese tallow.
