Maclura pomifera
Also called Horse-apple, Bois d'Arc, Hedge Apple, Bow Wood, Bodark, Mock Orange, Monkey Ball
Osage-orange is a small deciduous tree or large shrub, native to the south-central United States, widely planted as a hedge and windbreak. It grows best in deep, fertile soil and needs regular pruning to stay in bounds.
Maclura pomifera, commonly known as the Osage orange ( OH-sayj), is a small deciduous tree or large shrub, native to the south-central United States. It is a member of the mulberry family, Moraceae. It typically grows about 8 to 15 m (30–50 ft) tall. The distinctive multiple fruit resembles an immature orange, is roughly spherical, bumpy, 8 to 15 cm (3–6 in) in diameter, and turns bright yellow-green in the fall. The fruit excretes a sticky white latex when cut or damaged. Despite the name "Osage orange", it is not related to the orange.
Due to its latex secretions and woody pulp, the fruit is not usually eaten by humans and rarely by foraging animals. Ecologists Daniel H. Janzen and Paul S.
Maclura pomifera prefers a deep and fertile soil, but is hardy over most of the contiguous United States, where it is used as a hedge. It must be regularly pruned to keep it in bounds, and the shoots of a single year will grow 1 to 2 m (3–6 ft) long, making it suitable for coppicing. A neglected hedge will become fruit-bearing. It is remarkably free from insect predators and fungal diseases. A thornless male cultivar of the species exists and is vegetatively reproduced for ornamental use. M. pomifera is cultivated in Italy, the former Yugoslavia, Romania, former USSR, and India.
Osajin and pomiferin are isoflavones present in the wood and fruit in a roughly 1:2 ratio by weight, and in turn comprise 4–6% of the weight of dry fruit and wood samples. Primary components of fresh fruit include pectin (46%), resin (17%), fat (5%), and sugar (before hydrolysis, 5%). The moisture content of fresh fruits is about 80%.
Osage orange's pre-Columbian range was largely restricted to a small area in what is now the United States, namely the Red River drainage of Oklahoma, Texas, and Arkansas, as well as the Blackland Prairies and post oak savannas. A disjunct population also occurred in the Chisos Mountains of Texas. It has since become widely naturalized in the United States and Ontario, Canada. Osage orange has been planted in all of the 48 contiguous states of the United States and in southeastern Canada.
The Osage orange is commonly used as a tree row windbreak in prairie states, which gives it one of its colloquial names, "hedge apple". It was one of the primary trees used in President Franklin Delano Roosevelt's "Great Plains Shelterbelt" WPA project, which was launched in 1934 as an ambitious plan to modify weather and prevent soil erosion in the Great Plains states; by 1942, it resulted in the planting of 30,233 shelterbelts containing 220 million trees that stretched for 18,600 miles (29,900 km). The sharp-thorned trees were also planted as cattle-deterring hedges before the introduction of barbed wire, and afterward became an important source of fence posts. In 2001, its wood was used in the construction in Chestertown, Maryland, of the schooner Sultana, a replica of HMS Sultana.
