The leaves are arranged in whorls of three to six, lanceolate to
obovate or elliptic in shape,
****0 mm (2*1⁄**2 in) long and ****0 mm (1*1⁄*5*1⁄8 in) broad,
with an entire or spiny-serrated margin.
The flowers are produced in a long, slender, and simple raceme
****0 mm (**2 in) long,
the individual flowers ***5 mm (3⁄*9⁄*6 in) long, white to pink
or purple, with four tepals.
The fruit is a hard, woody, globose follicle with a pointed apex
containing one or two seeds.
The nutshell ("coat") is particularly tough and requires around
***0 N to crack.
The shell material is five times harder than hazelnut shells and
has mechanical properties similar to aluminum.
It has a Vickers hardness of *5.
The macadamia tree is usually propagated by grafting and does not
begin to produce commercial quantities of seeds
until it is **0 years old, but once established, it may continue
bearing for over **0 years.
Macadamias prefer fertile, well-drained soils, a rainfall of
1,***2,**0 mm (***0 in),
and temperatures not falling below *0 °C (*0 °F) (although once
established, they can withstand light frosts),
with an optimum temperature of *5 °C (*0 °F).
The roots are shallow, and trees can be blown down in storms;
like most Proteaceae,
they are also susceptible to Phytophthora root disease.
As of ***9, the macadamia nut is the most expensive nut in the
world, which is attributed to the slow harvesting process.
