This gorgeous flower is about six to eight inches across. You simply cannot imagine how impressive these cactus flowers can be. They are so large and so beautiful it is a shame that they last only for one, or at most two days. In fact, you have to catch them during the time of the day that they are in bloom. On our last outing, we saw evidence of quite a few of this type of flower that had already past their blooming time but this was one of the few that was still in bloom.
