History of Macadamia Nuts in Hawaii
The Macadamia nut is delicious and
a part of Hawaiian history
Hawaii is the macadamia nut capital of the world, growing 90% of the
world's macadamia nuts. One of the first things a traveler to Hawaii
notices on their arrival at the airport or first visit to any
convenience store is the huge displays of macadamia nut products, such
as gift packs of dry roasted nuts, chocolate covered nuts and macadamia
The macadamia nut tree originated in Australia. The macadamia was
classified and named jointly by Baron Sir Ferdinand Jakob Heinrich von
Mueller, Director for the Botanical Gardens in Melbourne and Walter
Hill, first superintendent of the Botanic Gardens in Brisbane. The tree
was named in honor of Mueller's friend, Dr. John Macadam, a noted
lecturer in practical and theoretical chemistry at the University of
Melbourne, and a member of Parliament.
The tree was first planted in Hawaii near in Kapulena on the Big
Island of Hawaii in 1882. William H. Purvis, a sugar plantation
manager on the Big Island, visited Australia and was impressed by the
beauty of the tree. He brought the seeds back to Hawaii where he planted
them at Kapulena. For the next 40 years, the trees were raised primarily
as ornamental trees and not for their fruit.
In 1921 a Massachusetts man named Ernest Shelton Van Tassell
established the first macadamia plantation near Honolulu. This early
attempt, however, met with failure, since seedlings from the same tree
would often produce nuts of differing yield and quality. The University
of Hawaii entered the picture and embarked upon over 20 years of
research to improve the tree's crop.
It wasn't until the 1950s, when larger corporations entered the
picture, that production of macadamia nuts for commercial sale
became substantial. The first major investor was Castle & Cooke, owners
of the Dole Pineapple Co. Soon after, the C. Brewer and Company Ltd.,
began their investment in macadamia nuts.
Eventually C. Brewer bought Castle & Cooke's macadamia operations and
began marketing its nuts under the Mauna Loa brand in 1976. Since
then, macadamia nuts have continued to grow in popularity. Mauna Loa
remains the most popular brand of macadamia nuts in the world
and their name is synonymous with macadamia nut products.
