Yew is the Wood of Death. Used for its strength for bows in Greek times. The yew tree's branches grow into the ground, thus when the central trunk dies, the tree lives on as the branches become trees. It symbolizes transformation, great age, and reincarnation. Yew is especially good in spells involving spirits or raising the dead, and also in the dark arts, as well as in defense magic and shield charms.
Yew's personality is Enduring. Element: Earth 

Wands with Dragon Heartstring cores are excellent for hexes, or for dueling, not to mention fire magic. They tend to choose a witch or wizard who is strong not only physically, but also emotionally, and who usually has very strong opinions on things, though they often tend to be strong willed and thickheaded as well.
