Smooth-shell Macadamia

'Smooth-shell Macadamia' (Macadamia integrifolia) is one of the two primary macadamia species grown in Florida, alongside Macadamia tetraphylla. Commercial varieties of M. integrifolia were developed by University of Hawaii plant breeders, including 'Purvis', first selected in 1936. Seven such varieties are presently recommended for planting in commercial Hawaii orchards.
