So I was at a friend's house whom I haven't seen for a long time and, unbeknownst to me, he has a nice basjoo mat. Taking a closer look, I noticed the undersides of the leaves, especially the younger ones, looked like this:
I haven't seen a huge number of basjoos in my life, but of what I have seen, none of them have had this characteristic.
Has anyone else seen a basjoo with this coloration before?
