Sorbus x thuringiaca, or oakleaf mountain ash, is a hybrid tree resulting from the cross between Sorbus aucuparia and Sorbus aria, both of which are native to Europe. Oakleaf mountain ash are adaptable to a wide range of soil pH levels, from acidic to alkaline, and thrive in full sun. It is relatively disease-resistant, with no major insect or disease issues reported, making it an easy choice for planting. This tree can also be successfully transplanted as a bare root. A notable cultivar, Fastigiata, has a fastigiate form and grows to twice the height of the standard species. The oakleaf mountain ash is valued for its aesthetic appeal, environmental tolerance, and ease of care, making it a versatile addition to both residential and commercial landscapes. Sorbus x thuringiaca drops small fruits and a moderate number of leaves, with the heaviest shedding in the fall.
