What a glorious mess, Bihai! I would guess you could cut it off and root it, and maybe even root pieces of the stem. If you had to outside it would probably get frosted and come back from the roots, right? So you wouldn't have anything to lose by trying, anyway. I don't envy you trying to get it out of the pot even! But it's a beautiful plant.

To easy , but wait until Spring bihai, the large bent stem will do best laid on the ground/surface of potting mix with the base planted . It will straighten up and shot all along the stem . You are going to get heaps of corms outta that pot. The tip will root very easily if cut off .
