I have this cacti and it is called Homocephala texensis. It made it thru our first winter here in the 'burbs of Pittsburgh, PA USDA zone 6. I did nothing to protect it - wet soil and 4 feet of piled snow from the driveway during February storms.
I live in Detroit,MI (USDA z6a). This plant has survived its first winter here. Although this winter has been a slight bit milder than usual, with a few minimums of just 3 above zero, I believe the plant could've taken an even slightly lower minimum than the lows endured this year. The only protection provided this plant...and I provide a similar form of protection on all my hardy desert plants..was a clear, thin plastic Victorian cloche. This prevents winds and our usual "winter wet" (snow, ice, cold rains, etc.) from touching the plant. The cloche went on October 1st, and will stay on until late April. Today is March 13th, the worst of winter has past, and the plant looks great.
