Common hawthorn is a thorny deciduous shrub or small tree and a member of the rose family, Rosaceae, that also includes cherry, lady’s mantle and almond. It is native to Europe, northwest Africa and western Asia but was introduced into the US and has become invasive in some areas. Also known as mayblossom and English hawthorn, plants grow 10-30’ tall, are densely branched, and have gray- brown bark with vertical orange fissures. The glossy green leaves are 1-1.5” long and have 3-7 deeply incised lobes. Clusters of 5-25 small white, five-petaled flowers have numerous red stamens and an unpleasant odor. They appear in late spring and give way to a one seeded red berry like fruit that is attractive to birds and other wildlife that aid in seed dissemination. Prolific seed production is responsible and wide dissemination has led to the invasive nature of the plant. The genus name, Crataegus, comes from Greek word krátaigos, the name of a related hawthorn. The specific epithet, monogyna, comes from the Greek words monos meaning single, and γυνή (gunḗ) meaning woman, and refers to the presence of a single stigma (female part of the flower).
