Pinus × schwerinii ‘Wiethorst’

Pinus × schwerinii, commonly known as the Schwerin pine or Schwerin's pine, is a hybrid pine species between Pinus wallichiana and Pinus strobus. It was first described by German botanist Jost Fitschen in 1930 in Ludwig Beissner's third edition of Handbuch der Nadelholzkunde. P. × schwerinii is named for Fritz Kurt Alexander von Schwerin, who owned the estate near Berlin where the hybrid was first observed growing in proximity to its parent species.
