The Common Hawthorn is a small, rounded deciduous tree with sprays of white flowers which are abundantly produced in May, followed by dark red berries in autumn. Crataegus monogyna thrives on most soils, including heavy ones.
Interesting fact: also known as the May tree, due to its flowering period, it is the only British plant named after the month in which it blooms. (thanks to Woodland Trust for this Information)
Crataegus monogyna reacts well to a severe prune if done when it is dormant and makes a fine garden tree.
