General Description

Producing large nuts, the Beaumont macadamia is well-suited for growth in dry, subtropical areas and has pretty, bright pink, pendent flowers, and reddish new leaves. A hybrid selection from crossing two Australian natives, the smooth-shelled (Macadamia integrifolia) and the rough-shelled (M. tetraphylla) macadamias, it is a very slow growing, evergreen tree that attains an upright yet rounded canopy. The foliage of macadamia tree is handsome. They are dark green and glossy, often with a wavy edge. In mid to late winter and extending into spring, long, pendent strings of tiny pink flowers dangle from the whorled leaf clusters. Pollinated by bees, the flowers become leathery round green, then blackish brown hard fruits. They will drop from the tree over a long period. The outer shell slowly cracks open to reveal a lighter brown, hard and oily nut. The usual beige-colored nutmeat that is delectable is obtained by roasting and cracking the extremely hard seedcoat.

Grow Beaumont macadamia in full sun in a fertile, deep soil that has good drainage and has an acidic to slightly alkaline pH. Tolerant of heavy clay, it is best in a sandy loam that remains moist. This tree has weak wood and should not be placed in a windy situation. Macadamia trees are self-fertile, but the proximity of another tree readily increased fruit production. Use it as a dual-purpose ornamental and nut tree in the lawn or general garden border. Although slow growing, it can also be grown in groups as a screen.

Macadamia trees will dependably produce fruits in warm, frost-free regions. In very humid, hot tropical areas the fruiting is inconsistent. Elsewhere it is ornamentally worthwhile because of its foliage and long strings of rare flowers.
