It grew some?

I marked the photo NOT the wall.  It's an indication of the overall height of it at purchase.  I have NO idea why it went all Cobra at the top; I expected the bend over, but the contortions too?

I doubt it'll not fit in my glass topped box to overwinter, might end up in the greenhouse or kitchen window cill/sill (If in doubt see here.) again.
I suppose the next target will be a different coloured flower? 
Sarracenia of unknown variety; except, maybe, to the grower?
