I was given this amazing plant five or more years ago by David Salman: I'm not entirely convinced it doesn't represent a hybrid with Pediocactus simpsonii. Once it's finished blooming, it's going into a trough with another (much paler) P. despainii. I agree with John Weiser that it is beyond stupid that we cannot import these from Canada.
By the way, this just sits outside all winter in its dinky pot: does just fine through -20F we had this year!
