I saw these flowering at Bachs Cactus Nursery and grabbed one that had 3 buds on it. One flower was allready open and got trashed by getting too friendly with a Mammillaria geminispina in the back seat on my way home. I knew I shouldn't have left them put it in the same box with the other cacti. Here's flower number 2 and another in spring 2007.
