Hawthorn is a large shrub or tree with thorny branches. It blooms in May with small, pinkish-white flowers in thick clusters which are followed by red berries.
The Ancient Greeks believed that hawthorn trees were seeded by lightning. The tree's links to the underworld and the supernatural meant that fires fuelled by hawthorn branches were important in rituals.
Hawthorn continued to be important in Roman times and a large amount of hawthorn berries have been found in a pit at Lullingstone Roman Villa. The pit might have been linked to rituals.
