Karpatiosorbus ×hybrida, commonly known as Oakleaf Mountain Ash, is a deciduous tree native to cool temperate regions of Central Europe, particularly found in mixed forests and mountainous areas. It typically grows to a height of 30-40 feet (9-12 meters) and a width of 20-30 feet (6-9 meters), with a rounded crown and a moderate growth rate. The tree is notable for its pinnate leaves that resemble those of an oak, and clusters of white flowers that bloom in late spring, followed by orange-red berries in the fall. The berries are not only ornamental but also provide food for birds and other wildlife.

Oakleaf Mountain Ash is valued for its attractive foliage, which turns a vibrant red or orange in the autumn, and its tolerance of urban pollution, making it suitable for city planting and residential landscapes. It is also used as a specimen tree or in mixed borders. This tree prefers full sun but can tolerate partial shade and requires medium amounts of water. It is adaptable to a variety of soil types, provided they have good drainage. While generally low-maintenance, it can be susceptible to fireblight and other diseases common to the Rosaceae family. Gardeners should monitor for pests and diseases and take preventive measures when necessary.CC BY-SA 4.0
