Crataegus crus-galli is commonly known as cockspur hawthorn, due to the sharp, thorny spurs on its branches. Some other synonyms for this species include Crataegus cruspidata, Crataegus pringlei, and Crataegus pinnatifida. It is a small, deciduous tree or shrub that is native to eastern North America and is often used in landscaping and gardening due to its attractive white flowers in the spring and bright red fruits in the fall. The tree's bark, leaves, and fruit have also been used for medicinal purposes for centuries. Despite its status as a popular ornamental tree, the cockspur hawthorn is considered invasive in some areas.
