Cool contest @czechglobalhosts and good on you for supporting this.
My choice is the Baobab tree from Africa
This tree is awesome. Well all Baobab trees (Adansonia in latin) in Africa are awesome. They live a long time, they grow huge fruit that makes a nice juice (or booze) and there are many many stories in many different African cultures that talk about the importance of this tree. Enjoy this photo from Southern Africa!
