Willow
Willow Tree
A tall tree with a thick trunk, the leaves hang low, right to the ground.
Very old willow trees yield more wood than most trees.
Willow trees are slow growing.
Willow trees will also kill trees around it due to it's thick foliage blocking the sunlight. If your planting a willow, you need to leave 2 tiles of grass between it and other trees.
Willow wood is most useful for creating Bows as it is a flexable wood & gives a bonus to bows.
