When i was growing this in tons, my original clone came from Clyde Bramblett, and after it multiplied and was divided and had plants growing out of the bottom of the pots...well you get the picture.
Anyway, some turned so dark and narrow-leafed they were purple, while others sitting right next to those were still green and some were red to orangish like Joseph's. These were all from the same plant. Maybe somebody can divide theirs and try some in peat, lf sphagnum, ect, since I did not really pay attention back then.
You really have to be a skeptic when you see some advertized as "all red" clone, as you never know.
