Although the macadamia tree is a popular commercial crop in Hawaii， it’s actually native to northeastern Australia. The tree is also grown in Africa， Asia， and Latin America， as well as in the warm climates of Florida and California in the United States. The macadamia tree is part of the Protaceae family. Although a slow grower， once the tree begins to bear fruit it continues to produce for years to come. Its foliage is a rich， deep green hue， with oblong blunt-tipped leaves that have spiny， serrated margins. These leaves develop in groupings of three to six， but almost never develop singly. When it flowers， its blossoms grow on long spikes called racemes， each with between a hundred and a hundred and fifty flowers on it. The average tree produces about 2500 flowers in a given flowering season. Trees take seven to ten years before they start to produce harvestable nuts. The tree will grow to a height of between 7-40 feet， although ones used in commercial growing are usually kept short for ease of harvest. Its nuts develop inside a round and hard woody shell. This shell is about five times harder than a hazelnut to crack， and has a whole host of uses on its own.
