Gleni, have you had any chemicals sprayed near your Olympic Showcase? Even chems the neighbor may have sprayed that could have drifted? Sometimes things like Round-up can cause mutations on plants. That would be my first guess. But then I don't know the ancestors of OS lol so maybe it does have some doubling aunties that are showing up now... Some dl just double when they feel like it once in a while, for fun I guess!
