The commercial form of Iris danforiae is a good example, it is sterile
because it is triploid. This results in bigger flowers for garden use, but
also makes it sterile. If it were in the wild it would die out unless it
could reproduce vegetatively. In that case there could be a significant
sterile wild population of the species. (In my opinion not likely to happen
in this case). If the sterile triploid were to be stronger and compete with
the diploid material, then  one day there might be only a sterile triploid
form of the species in existance.
