Hawthorn: Crataegus Monogyna
Hawthorn is very much associated with the month of May, and the appearance of its bright, white flowers heralds the change from spring to summer. It is prolific in hedgerows, scrub and woodland throughout the UK and Ireland, and a single tree can grow as tall as 10m. In pagan times, hawthorn was a symbol of marriage and fertility, but in the Middle Ages, it was never brought into homes, as people believed it was a harbinger of illness and death.
