It is cultivated among others in Central and South America and southern Africa, but also thrives under cooler, oceanic climate embossed. In Central Europe it is rarely planted and is almost only seen in botanical collections.
Despite its tropical distribution, the Mexican White Pine is surprisingly cold tolerant; from the culture in the U.S. state of Pennsylvania as well as in Scotland is reported of specimens that have survived -30 ° C.
