Theobroma cacao, also known as the cocoa tree and the chocolate tree, is a small, evergreen tree in the family Malvaceae. It produces cocoa beans which are used to make cocoa mass, cocoa powder, confectionery, ganache, and chocolate. Cocoa beans are one of the most valuable commodities in the world.
Taxanomy of Theobroma Cacao
Theobroma cacao is a member of the Malvaceae, or mallow, family. Theobroma cacao is the only member of the genus Theobroma. The scientific name Theobroma cacao literally means “cacao, food of the gods”.
Theobroma cacao was first classified by Carl Linnaeus in 1753. The genus name Theobroma comes from the Greek words for "food of the gods." The species name cacao is derived from the Nahuatl word for "cacao bean".
Description of Theobroma cacao Tree
The Theobroma cacao tree grows to a height of about 20 feet (6 meters). The trunk is straight and the bark is smooth, thin, and pinkish-gray in color. The branches are slender and spread out evenly. The leaves are oblong-shaped, dark green, and measure about 4–8 inches (10–20 cm) long and 2–3 inches (5–7 cm) wide.
The flowers grow directly from the trunk, branches, or leaf axils. They are small, white, and have 10 petals arranged in a star-like pattern. The fruit grows directly from the trunk or branches. It is oval or pear-shaped, measures 3–6 inches (7.5–15 cm) long, and is green or yellow when ripe. The fruit pulp is pink, red, or purple and contains 20–60 seeds.
In the wild, cacao trees can live up to 100 years. However, most commercially grown cacao trees only live for about 20 years because they are heavily pruned to make harvesting the fruit easier.
Geographical Distribution of the Cacao Tree
The Theobroma cacao tree is native to the Amazon Basin and the Orinoco Basin in South America. It is believed to have originated in the region that includes the countries of Brazil, Ecuador, Peru, and Bolivia.
It was first domesticated by the Olmecs, Maya, and Aztecs in Mesoamerica. The Spaniards introduced the cacao tree to the West Indies and Mexico in the 16th century.
Today, it is cultivated in tropical regions around the world, including Africa, Southeast Asia, and Central and South America.
Ecology of the Cacao Tree
The Theobroma cacao tree grows best in tropical climates with high humidity and ample rainfall. It prefers deep, well-drained soils.
It is shade-tolerant and can grow under a canopy of other trees. However, it typically produces more fruit when grown in full sun.
The trees are generally propagated by seed. However, vegetative propagation methods, such as grafting and rooting cuttings, are sometimes used.
The trees begin bearing fruit at 3–5 years of age and can produce for up to 50 years. It will not tolerate prolonged drought or frost. It is also sensitive to wind and should be protected from strong winds.
