Report an issue with this species

Common Hawthorn is a deciduous tree or shrub growing up to 10 meters tall, featuring sprawling, thorny branches, lobed leaves, and showy white to pink flowers in late spring, followed by persistent red fruits. Native to Europe, it attracts bees and birds and can form dense thickets, sometimes exhibiting invasive tendencies in introduced regions.
