Pinus ayacahuite

Pinus ayacahuite, also called ayacahuite pine and Mexican white pine,

Despite its tropical origins (the natural range is entirely south of the Tropic of Cancer), it is surprisingly tolerant of cold, having survived temperatures down to nearly -30 °C in cultivation in Scotland and Pennsylvania, United States. It is grown as an ornamental tree in parks for its attractive foliage and very long cones, among the longest that can be grown in many temperate areas.

The wood is valuable, used for general indoor construction work.
