Centerless grinding newbie questions

Suppose a flower. maybe a rose. Want to grind the stem, but not even inconvenience the petals. Can it be done?
Can you influence it to get some desired center exactly on center? If
so, how expensive is that?
Thanks,

I would think it's impossible with a centerless grinder. On a surface grinder or universal grinder one would probably use a tool like a Harig grind-all or similar:-

It's a bloody expensive one as well!
I suppose any engineering hobbyist worth his salt could make one, if he needed it that much.

I used an inexpensive 5C spin index to neck down this tap on my surface grinder: http://picasaweb.google.com/KB1DAL/Temporary#5289374956505595074
The grinder is a clapped-out Delta/Rockwell that appears to have been the inspiration for the tilting head on the Quorn.
