I think I understood what you meant, as my hederaceum specifically has reddish on the older growth and all green on the newer growth. It could be an acidity thing, or light or whatever makes the little guy tick, lol. But that is just on the same plant, so it made your larger point easy to grasp. I didn't find your article to be too difficult to read the other day, so I'll just be happy with it :). And don't worry, if you mess up, someone will call it to your attention, I'm sure.
