This small Hatiora was putting out some flowers last May at the same time our Disocactus ackermannii was making flowers. I tried to cross pollinate these two plants and thought that it didn't work because the Disocactus never made any seed pods with the flowers which were crossed. Later I was surprised to see that this H. gaertneri had seed pods on it. It seems that the H. gaertneri pollen wouldn't take in the D. ackermannii, but the D. ackermannii took in the H. gaertneri. This seems sort of strange, but I would be happy if these seeds are actually viable and grow into plants. Sometimes combinations like this will make seed pods, but they will be empty or the seeds will be sterile. We'll have to wait and see how they develop and plant the seeds if there are any.
