I bought a lot of trailing begonia plugs this year and the display has
been simply amazing.

I understand that begonias can be overwintered if they are the type
which grow from tubers, but I don't know which type mine are.

The variety is called 'Orange Sparkle' and I have posted a picture of
what I hope is a tuber on my Picassa web album.

Please could somebody tell me if the hard, pink nobbly thing at the
bottom of the stems is a tuber?

It looks like one. It won't be one of these, even though it looks
a bit like one :-)
