Crataegus monogyna, or Hawthorn, is a deciduous shrub and part of the rosaceae (rose) family. While called a shrub, Hawthorn plants grow up to 6m tall, producing little white flowers in the late spring.
Hawthorn is extremely valuable in herbal medicine. It is said to increase blood flow to the heart and restore a normal heartbeat. Additionally the fruit is high in antioxidants, though it is reported to be not very tasty raw. More often the fruit is used to make jams and preserves. The flowers are also used in desserts. The leaves can also be dried to make a tea.
