Hah hah. Don't be a hater, but what I think he meant to say was that this plant grows so slowly (or not at all) that if you plant it where it gets lots of light exposure the white leaves will turn green because they will get covered with algae. Actually, maybe that IS was he was saying and it just translated approximately. Update on my ASW planted 13 days ago is it looks very much like it did the day it was planted (which isn't a big surprise other than I'm happy it hasn't all immediately melted/died).
