Crataegus Marshallii, commonly known as the Parsley-Leaved Hawthorn, is a type of hawthorn tree that is native to the southeastern United States. This species is also referred to as the Parsley-Leaf Hawthorn, Marshall's Hawthorn, Small-Leaf Hawthorn, and Parsley-Leafed Thorn. These names are derived from their distinguishing features, such as their small and finely divided parsley-like leaves. The tree produces white flowers that emerge in the spring, followed by small red fruit that is consumed by birds and other wildlife. Crataegus Marshallii has many medicinal properties, including its use as a heart tonic and in the treatment of high blood pressure.
