Toni Ransfield a master (Or should that be mistress .... sorry Toni!) at that did a tutorial. It's not quite that simple, there's a LOT of work involved. I think the Tut is in the library?
Alternatively, do a google search for "polymer clay canes" "polymer clay flower canes" etc & go from there.
Hope that helps.
I haven't made one yet, but I got a ton of clay to practice with. It seems you buy the canes already made with flowers (that is half the work). You can cut them and apply them to tubes with a clay base.
