Oak

This is the coast live oak growing in my backyard. It started out as a sapling when we moved in, but it is huge now. It is home to many insects, which attracts birds. But this post isn't really about my tree. It is about tree magic. 

To the druids, the oak was sacred. Not much is known about the Druids, because they didn't write anything down. But they worshiped outside in groves of oaks. Trees are also home to many small magical creatures, like elves,sprites, fairies and dryads. 

When the Christians wanted to covert the Druids, they built  churches in the groves. I guess it worked, I think the Druids died out, but it seems sacrilegious to me.
