Fairy Trees

Out for a walk today and I started to chat to a grandma who had her little granddaughter with her.  The little girl was carrying some wild flowers and I was telling her how nice they were.  The grandma told me that they were going to leave them at one of the fairy trees.  I didn't know about them but as I walked on I spotted quite a few of them with little doorways at the base of their trunks and decorated with all sorts of little things.  Extra one attached.
