Macadamia (Beaumont)
Macadamia integrifolia 'Beaumont'
One of the most cold-tolerant macadamia varieties, Beaumont makes it possible to grow these premium nuts in subtropical climates where other varieties would fail. This Australian native produces the rich, buttery nuts that command premium prices in stores, with excellent kernel quality and good cracking characteristics. The evergreen tree also serves as an attractive landscape specimen with glossy leaves and fragrant flower clusters.
