Dear Twig: What are hedge apples? My father points them out to me when weâre driving in the country. Oo, I like hedge apples. The hedge apple tree is one of my favorites. Itâs also called Osage orange or, scientifically, Maclura pomifera. The hedge apple/Osage orange is a medium-size tree that grows big honkinâ fruit. These fruit arenât apples and they also arenât oranges. Instead, theyâre green like a frog, as big as a softball and wrinkled like a brain. If Newton had been konked by one he wouldâve been knocked silly. I donât know Bob the Bugâs excuse. Some folks risk konking. They gather hedge apples then put them in their homes. They claim hedge apples keep out pests. Whether this actually works or not hasnât been proven by science. But one study has shown that certain oils in the fruit, some of them unidentified, make roaches run away. Osage oranges are native to parts of Texas and Oklahoma. But you can find them growing in most other states. They were widely planted as living fences before the invention of barbed wire. Another common name is bodark, or bois dâarc -- French for âwood of the bow.â Osage orange wood makes great bows. Long-lasting fence posts, too. All in all itâs quite a tree! Twig Hey Editor!
