This is one of a few hundred that were in bloom at a friend's home in Riverside. When I see cacti in bloom, I often think about the 1969 movie Cactus Flower of the same name starring Goldie Hawn, Ingrid Bergman and Walter Matthau. It is a romantic comedy with everyone ending up with the "right" partner in the end. Hard to believe that was fifty years ago. But love and comedy were much more innocent then.
Adult Entertainment? Like I said, those were different times.
