The macadamia seed is planted in a sand bed and originally Macadamias were found in Australian. These days they grow in Hawaii, South Africa, Kenya, Malawi, Zimbabwe, Costa Rica, Guatemala and Brazil. Macadamia trees grow slowly to heights of 12 to 15 metres. They have shiny dark green leaves, and bear sprays (racemes) of long, delicate, sweet-smelling white or pink blossoms. Each spray of 40-50 flowers produces from four to fifteen ‘nutlets’ which will eventually ripen into nuts.The nuts themselves grow encased in a hard, woody shell, which is protected by a green-brown fibrous husk. In its natural state a macadamia tree will have flowers, nutlets and mature nuts growing simultaneously, in profusion for much of the year. The nuts fall to the ground between February and June each year.
