The wood we often call hedge is Osage Orange, here's the full story.
Maclura pomifera, commonly known as the Osage orange, is a small deciduous tree or large shrub, native to the south-central United States. It typically grows about 8 to 15 metres tall. The distinctive fruit, a multiple fruit, is roughly spherical, bumpy, 8 to 15 centimetres in diameter, and turns bright yellow-green in the fall. The fruits secrete a sticky white latex when cut or damaged. Despite the name "Osage orange", it is not related to the orange. It is a member of the mulberry family, Moraceae. Due to its latex secretions and woody pulp, the fruit is typically not eaten by humans and rarely by foraging animals. Controversial suggestions have been made that it was consumed by extinct Pleistocene megafauna, but these claims have been criticised as lacking empirical evidence. Maclura pomifera has many names, including mock orange, hedge apple, hedge, horse apple, monkey ball, monkey brains and yellow-wood. The name bois d'arc has also been corrupted into bodark and bodock.Wikipedia
Native American's used it to make bows! We mostly use it for firewood and fence post since it is so dense and readily available. I know if you get some of the sap (right after cutting) on your leather gloves they will last 3 times as long as without it.
