Pinus × schwerinii 'Wiethorst' / Wiethorst Schwerin's pine

Pinus x schwerinii 'Wiethorst' is a dwarf selection of Schwerin's pine, an interspecific hybrid of Eastern White pine (P. strobus) and Himalayan pine (P. wallichiana). It is a small, upright-growing tree with fluffy light-green needles displaying silvery undersides. A valuable trait of this tree is that it will produce abundant seed cones at a young age. Expected annual growth is 6 to 8 inches (15 - 20 cm), producing a 6 foot (2 m) tall tree after 10 years in the landscape.

This cultivar originated as a witch's broom found by Johann Wieting of Giesselhorst Germany. The cultivar name is actually a combination of the names Wieting and Giesselhorst. This cultivar is very desirable to the conifer collector because it is one of the few existing cultivars of Pinus × schwerinii. It was also one of two plants selected in 2014 for inclusion into the ACS Collectors' Conifer of the Year Program.
