What am I?

My tree is about 5 years old and I have forgotten what it is! 
help with identity would be great,  but more importantly...... what do I need to do with it!

The tree is probably about 1ft tall and keeps growing up from the green bit at the end of the branch. Do I let it keep growing as it is or does it need some training to stop it growing bigger?

Advice from the experts as its a lovely little tree and I don't want to ruin/kill it. 
      

Google Leaf can probably identify it. There are plant specific apps that would probably do as well.
