Facts

Macadamia nuts, considered by some to be most delicious nuts in the world, are shaped like shelled hazelnuts but are more oily. The nut oil is rich in palmitoleic acid, also found in young people’s skin. It is now being examined for use in creams intended to improve the appearance of ageing skin.

Where it grows

Native to Australia (Queensland and New South Wales). Cultivated in the USA (including Hawaii), West Indies and South Africa. Grows in alluvial silts and fertile volcanic soils in upland tropical and subtropical zones.

Conservation story

The macadamia is listed as 'vulnerable' by the International Union for Conservation of Nature.
