The Powers of the Trees

OAK - The Oak Green Man is the "King of Trees" and is been considered sacred by just about every culture. The Celts held the oak in particular esteem because of its size, longevity, and nutritious acorns. Magic wands were made of its wood. Acorns gathered at night held the greatest fertility powers. The Druids and Priestesses listened to the rustling oak leaves and the wrens in the trees for divinatory messages. Burning oak leaves purifies the atmosphere. It can be used in spells for protection, strength, success and stability; the different varieties will lend their own specialties to the Magic. A very valuable Green Man for your home. 

HOLLY - A beautiful white wood with an almost invisible grain, it looks very much like ivory. Holly Green Man  is associated with the death and rebirth symbolism of winter in both Pagan and Christian lore and is important to the Winter Solstice. Holly may be used in spells having to do with sleep or rest, and to ease the passage of death. A bag of leaves and berries carried by a man is said to increase his ability to attract women. 
 A very attractive Green Man.

ROWAN - Also known as Mountain Ash, Witchwood and Sorbus Apple has long been known as an aid in protection and control against enchantment and beguiling. Sticks of the Rowan were used to carve Runes on. Its lovely red berries feed the birds in winter. The Rowan was sacred to the Druids and the Goddess Brigit. It is a very Magical tree used for rods, amulets and spells. Wands made from the rowan are for knowledge, locating metal and general divination.  The protection offered by the Rowan Green Man is a positive asset to any home.

WILLOW - Also known as White Willow, Tree of Enchantment and Witches' Aspirin. Once of the seven sacred trees of the Irish, a Druid sacred Tree. The willow Green Man is a Moon tree sacred to the White Lady. Its groves were considered so Magical that priests, priestesses and artisans sat among these trees to gain eloquence, inspiration, skills and prophecies. For a wish to be granted ask permission of the willow, explaining your desire. Select a pliable shoot and tie a loose knot in it while expressing what you want. When the wish is fulfilled. Return and untie the knot. Remember to thank the willow Green Man and leave a gift. 

YEW - Another important tree to the Winter Solstice and the deities of death and rebirth. It is a beautifully smooth, gold-colored wood with a wavy grain. The Irish used it to make dagger handles, bows and wine barrels. The wood or leaves were laid on graves as a reminder to the departed spirit that death was only a pause in life before rebirth. All parts of the tree are poisonous except the fleshy covering of the berry. The Yew Green Man may be used to enhance Magical and psychic abilities, and to induce visions.
