I bought one of those "Blue Ischia" trees too, back when there was a lot of chatter about them last year. I separated it into 3 trees (they were all tiny), and they're growing nicely now. But the leaves don't look anything like your pics in that other thread. It does sound kinda suspicious (but then, the whole idea of "Blue Ischia" sounded pretty suspicious to start with). If I get a chance after I get home, I'll make some pics of the leaves and post them here.
