When to see

January to December


In May, Common hawthorn erupts with masses of creamy-white blossom, colouring our hedgerows. During the autumn and winter, red fruits known as 'haws' appear. Common hawthorn is a rich habitat for all kinds of wildlife, from Hawthorn shield bugs and Yellowhammers that feed on the haws, to Wood mice and Slow worms that shelter in the thorny thickets.

What to look for

Common hawthorn has shiny leaves, divided into three to seven pairs of lobes, and five-petalled, sweet-smelling flowers. It can be distinguished from the similar Midland hawthorn by its more deeply lobed leaves and the fact that it only has a single seed in each fruit.

Where to find
