From Oaxaca, Mexico, Mammillaria huitzilopochtli is a solitary cylindrical cactus to 5 inches tall and 3.5 inches wide. It's hard spines recurve severely against the body, making it a very touchable cacti. One would almost have to purposely rub it the wrong way to get poked. It's bright pink flowers appear in late winter.
     This came from Bachs. I love the spination and flowers.
