Pinus x schwerinii 'WIETHORST' dwarf Schwerin's pine
Pinus
Schwerin’s pine is an interspecies cross between Himalayan pine and Weymouth pine. It was found by the earl Schwerin in his park in Wilmersdorf (near Berlin) in 1905 and has become a collectors’ item ever since.
Wiethorst is a witch’s broom of Schwerin’s pine, found and named by Johann Wieting in Gieelhorst, Germany. It is dwarf, slow growing version of this pine with symmetrical, pyramidal shape and dense habit. It has beautiful, 10-12 cm long, silvery blue-green, and always pendent needles. In summer numerous light green, slim cones are produced even on young plants. Pruning is not required to achieve a compact shape.
All pines love sunny sites and dislike wet ground. Though, this pine benefits from constant moisture and makes extra beautiful plants when it does not suffer from drought. Its root system can get used to sites near ponds and water streams and will benefit from extra humidity brought by presence of water features. It can live on either fertile of poor soil. Hardy to about -34°C (USDA zone 4).
