Faerie Talk (Common Hawthorn)
A portal to other worlds, the home of faeries, or the flower that sparks a little twinkle in your eye, the common hawthorn is a tree that is as understated as it is revered. This spring bloomer is planted all over the world as a street tree, and grows commonly in the forests and hedgerows of Europe and the UK.
