Welcome to ATP FleudeLisCanna.
I really like this kind of information. I'm supposed to be growing this cultivar. At least it was tagged as C. Tropicanna and more or less looks the same. The foliage on mine has tended to become more burgundy with a lot less color striping under my cultivation practice. Infertility in plants is often the result of a hybrid plant with two distinct parents of similar species. If the origins were in Africa, do you know what those parents were if that is the case here?
