Spherical tree which may grow rather slowly when young but can eventually reach around 12 m. The twigs are strikingly orange-brown. The mature bark is grey-brown and peels off in rough strips. The stiff, rather short needles have a slight twist and are 4 to 6 cm long. They are in twos and intense grey-blue. The grey-brown cones hang alone or in clusters of 2 to 5. This Pinus even grows in extreme conditions although it prefers well-drained, lightly acidic, quite dry soils. Very resistant to (sea) wind and not sensitive to air pollution. The cultivar name, ‘Glauca’ was given to it after 1 January 1959 and is not valid according to the nomenclature rules. This takes nothing away from the fact that it is a fine tree.
