Pyrus calleryana, commonly known as the Callery pear, is a deciduous tree native to China and Vietnam. It typically grows to a height of 30 to 50 feet and features glossy green leaves that turn vibrant shades of red and purple in the fall. The tree produces small, white flowers in early spring, which are often fragrant and attract pollinators. This species is widely used in landscaping due to its ornamental qualities and ability to thrive in various soil types. However, Pyrus calleryana has become invasive in some regions, outcompeting native plants and disrupting local ecosystems.
