There is something about the flowers of this Silver Torch cactus that remind me of something else. Maybe a bird, or chicken, or a tragic disease? I can't quite pinpoint it.
Cleistocactus blooms are just as you see them. They don't open much more than shown in the photo. The ends open up a bit, and then after a day or so, the ends shrivel. The name, Cleistocactus, is Greek for 'closed cactus', referring to the blooms.
