Macadamia 'Queen Anne' (Macadamia integrifolia)
Mature Air-Layered Fruit Tree
For a garden with the exhilaration of an apocalypse and the calming benefits of horticulture, tend to Macadamia integrifolia “Queen Anne.” This macadamia plant is native to rainforests in southern Queensland, Australia. It was first introduced to Hawaii in 1837, where they are now grown commercially.

Macadamia integrifolia appreciates a little coddling as a young sapling. As with most nut trees, it’s an investment in the future: Excellent care now will yield a lifetime’s harvest of macadamia nuts. With good hydration, protection from extreme weather, and pruning at the end of the growing season, you will be pleasantly surprised with the production power of this tree.
