Where Do Macadamia Nuts Come From?
Macadamia trees, which produce the macadamia nut, grow natively in Australia. The trees grow up to 40 feet tall and have elongated leaves that grow in small groupings. Macadamia nuts have a creamy texture. The meat of the nuts is very light brown, almost white, in color.
Ferdinand von Mueller, a German-Australian botanist, named the macadamia in 1857. He named the tree after John Macadam, a Scottish-Australian chemist. Macadamia trees were introduced to Hawaii in the late 1800s. However, the macadamia nut industry didn’t really become big business in Australia until the 1970s.
Today, most of the macadamia nuts that make their way around the world are grown in Hawaii. The U.S. alone eats a little bit more than half of the entire macadamia nut consumer market. That’s a pretty popular tree nut.
Macadamia trees grow in rich soil in warmer climates with lots of rainfall. Macadamia trees grow in environments that have no frost. They’re evergreen trees that produce nuts year-round. Growing macadamia nuts is possible in USDA hardiness zones 9 and 10.
Hawaii provides an ideal climate for the macadamia nut tree. The Hawaiian Macadamia Nut Company leased 75 acres of land in Honolulu and began the first macadamia tree orchard in Hawaii in the 1920s, beginning an industry that continues to thrive in the state to this day. Macadamia nuts are also called “Hawaii nuts” and many macadamia companies have made their homes in the state.
Amazingly, all of the many, many macadamia nut trees that thrive in Hawaii came from a small group of trees in Queensland, Australia. In fact, they all may come from the same tree.
As macadamia nuts grow and ripen, they naturally drop from the tree. Special tools are used to collect the nuts, which are then put through processing machines that remove the tough outer husks. Sometimes, the shells are removed through additional processing equipment, though the nuts e also sold in their shells.
