fairy tree

Almost all kinds of tree found in the Celtic countries have been thought to have special powers or to serve as the abode of the fairies, especially the magical trio of oak, ash, and thorn. Next in rank are the fruit-bearing trees apple and hazel, followed by the alder, elder, holly, and willow. The esteem given different trees varies in different parts of the Celtic world; on the Isle of Man, the phrase ‘fairy tree’ denotes the tramman [elder]. D. A. MacManus devotes a chapter to Irish fairy trees in The Middle Kingdom (London, 1959).
