About
Nothofagus antarctica (Antarctic beech; in Spanish Ñire or Ñirre) is a deciduous tree or shrub native to southern Chile and Argentina from about 36°S to Tierra del Fuego (56° S), where it grows mainly in the diminishing temperate rainforest.
Its occurrence on Hoste Island has previously earned it the distinction of being the southernmost tree on earth; however, in 2019 it was established that N. betuloides was found further south, on Hornos Island. N. antarctica is present on Hornos as well, but the southernmost individual is slightly further north (17 m) of the southernmost N. betuloides.
How to grow it
Nothofagus antarctica has been planted on the North Pacific Coast of the United States and in Great Britain where it thrives. Trees planted in the Faroes, which were imported directly from its southernmost distribution in Tierra del Fuego, have shown good hardiness.
NB: Lophozonia moorei, found in Australia, is also referred to as "Antarctic beech".
