Plant Species of the genus Bertholletia

Information about this genus
Name: Bertholletia
Cultivation: CULTIVATION: The Brazil nut is very much a plant of the wet-seasonal tropics. To thrive it needs hot humid conditions, plenty of moisture when in leaf and humus-rich soil. The soil of its forest homeland is often nutrient-poor and feeding will certainly improve the quantity and quality of the nut crop. While almost all the Brazil nuts sold are collected from wild plants, there is no reason why the trees could not be propagated from seed, and this may soon be necessary as the tree is endangered in some parts of its range.
Description: Very rarely cultivated, even for commercial crops, this genus includes just one species: a deciduous tree from the Amazon area that can grow to well over 120?ft (36?m) tall. While it is the source of the very well-known Brazil nut, few gardeners would recognize the tree from which the nuts come. It has large leaves that fall in the dry season, and panicles of flowers that develop into a 6?in (15?cm) woody fruit up to about 5?lb (2.2?kg) in weight in which up to 24 individual nuts are arranged like the segments of an orange.
