This year the Hawthorn, or May, is everywhere. My Mum used to call the blossom "bread and butter", I didn't know why until I stumbled across Robert MacFarlane's "Words of the Day: "bread-and-cheese" - English regional nickname for the very young leaves of the hawthorn, which can be eaten; also used for the edible seedheads of the mallow, silverweed roots & the youngest beech leaves (sometimes also known as "bread-and-butter")."
