There are two types of hawthorn in the British Isles. They’re identical except in the month of May when they’re easily told apart by the prolific white or pink blossom of varying intensities and it’s a certain indication that spring’s underway in earnest. Hawthorn is often called May by the older generation. There’s a traditional rhyme: ‘Cast ne’er a clout ’til May be out.’ meaning don’t take off your your winter clothes until either the hawthorn is in full blossom or the month of May is over. It’s a time of hope, new life and love.
