Macadamia is a genus of four species of trees indigenous to Australia, and constituting part of the plant family Proteaceae. Other names include Queensland nut, bush nut, maroochi nut, bauple nut, and Hawaii nut. They are native to northeastern New South Wales and central and southeastern Queensland. The macadamia nut tree is a fast-growing evergreen tree with heavy, dark green foliage. Macadamia trees commonly grow to 18 meters (60 feet) high and 15 meters (49 feet) wide. Its leaves – which are blunt-tipped, oblong, and generally a foot or more longer – develop in either whorl of twos, threes, or fours, but are rarely solitary.
Macadamia flowers are small and whitish, hassled, and growing on long spikes, while its nuts can ripen throughout the year, though they primarily ripen in the fall and the spring. the macadamia needs rich well-drained soil and 130 cm (50 inches) of rain annually. The fruit of this regal tree is a nut with a shell so hard it takes a hammer, a vise, or a specialty tool to crack it.
The highest quality macadamia kernels are not only free of defects or insect and fungal damage but also contain at least 72 percent oil. The kernels with less than 72 percent oil are usually immature and harder and will over-brown when roasted. Macadamia nuts are tree nuts that have a subtle, butter-like flavor and creamy texture.
