Red Hot Chilli Peppers?

Well these are my chillis. I got them as freebie seeds when we went to a mexican restaurant in London a while ago. I had planted them and not alot happened for a very long time - despite my loving attention. But they seem to have sprung with spring so I re-potted them yesterday and now have high hopes.
I'm growing them not because I have a great interest in chillis (though we do get through a few) but because I can!
