Because it got a little crowded in New and old England on this map I added a map of North-America and one of Europe.
Still looking for the places where the following trees grow: Beech Tree of Valeria, maybe Lilac from resoRevo, Cedar from Kristine, the Redwood from Neighbor and the tree from Sue H. – please leave a comment! Thanks

The Tree Year 
I know I haven’t updated the maps lately. I’m sorry, cause it was lots of fun to see where are all those trees grow. For the rest of the year I’ll just leave it like that – I hope it’s ok with you. Whenever you find a way that people can put their own locations, drop me a line 🙂
