It's a WHAT?!? Mk ll

Some time ago I/we experienced our first Poinsettia as a houseplant.  Last time I was through at Chez Jerra I remarked "TWO Pocies?!?"
(See link for explanation.)
It transpired he actually had three.  I had, in no way, intended a hint - BUT - as I had pawned off the odd extra plant on him, he retaliated; and next Jerraday, which fell, unusually, on a Wednesday this week he retaliated by donating this one to me.  I know, now, theoretically, how to return its Christmassy, festive colour; whether I can is another kettle o' fish entirely though.
