Those bean looking shoots are seed pods. The plant can take temps below freezing but not as low as will occur in a typical Amarillo winter. If you bring it in you will need to provide a very bright window to keep it growing over winter. Otherwise I might try to find a cold but protected indoor spot such as a garage where it could go dormant, but not drop below about 28 or 30 degrees.
Thanks for the question. Please stop in again soon!
