Only 2 of these 3 species (Macadamia integrifolia and Macadamia tetraphylla) can be eaten raw.

Macadamia trees were first planted in Vietnam in 1994 when the Forest Tree Research Center of the Vietnam Forest Science Institute planted 10 trees from seeds and planted them in Ba Vi, Hanoi. After that, macadamia trees were tested and propagated in many different provinces, mainly in the Central Highlands and Northwest. Since 2000, the area of macadamia plantation in Vietnam has increased gradually and in 2018 reached about 2,000 hectares of concentrated planting. In September 2016, according to the survey results of the macadamia development planning project in the Central Highlands of the Institute of Forest Investigation and Planning (under the General Department of Forestry), the area under macadamia plantations in the western provinces The original area is about 1,630 ha, of which Kon Tum 50 ha, Gia Lai 80 ha, Dak Lak 500 ha, Dak Nong 600 ha and Lam Dong (Lam Ha) 400 ha.
