Macadamia

The macadamia tree traces its origins to the subtropical rainforests of Queensland and New South Wales, Australia, where Indigenous peoples have valued the nuts for thousands of years. European botanists first documented the species in the 1850s, naming it after Scottish-Australian chemist John Macadam. Commercial cultivation remained limited until the 1920s, when Hawaii became the site of the world's first macadamia plantations, introducing the nut to global markets. Despite its Australian heritage, Hawaiian growers pioneered large-scale production, and the nut became synonymous with tropical luxury. Fragrance chemists began exploring macadamia oil's aromatic potential in the late 20th century as the industry sought natural ingredients with gourmand character. Today, macadamia cultivation supports sustainable agricultural practices in both Australia and Hawaii, appealing to fragrance houses prioritizing ethical sourcing.
