Save. Macadamia trees (Macadamia integrifolia) grow in warm, tropical and subtropical climates in U.S. Department of Agriculture plant hardiness zones 9 through 11, with proper care. The trees produce fragrant light pink flowers in spring and early summer, and the glossy green leaves provide year-round interest. Mature macadamia trees can produce 30 to 50 pounds of nuts each year when grown properly.
