Alder: The Alder, like the Willow, is a water-loving tree. Its timber is oily and water resistant and therefore used extensively for underwater foundations: parts of Venice and many medieval cathedrals were built on Alder piling. Bran the Blessed, or Bendegeit Bran, is the god liked with this tree in the Ogham alphabet.
Hazel: As well as poetic skill, this Ogham card represents intuition, the power of divination leading straight to the source. Hazel twigs have traditionally always been used for divining because of their pliancy and affinity with water.
