    The media is a pretty standard highland mix of sphagnum, perlite, orchid bark (if I remember correctly), and a bit of laterite. The edwardsiana are in a location that stays pretty humid, so I decided to tear out most of the sphagnum top layer and replace it with laterite, which should leech into the soil for the benefit of the plants and prevent any fungus gnats from turning it into a daycare center (I've noticed some flying around recently). I've done the same thing with other highlanders that grow in these ultramafic clays, such as attenboroughii, macrophylla, deaniana, villosa, peltata, etc., and have noticed an improvement in growth that seems to be exhibited by thicker petioles and darker lamina.

    Mato and DonH you guys are definitely growing them well! I've noticed some of the seed grown Eddie's have a lighter coloration than the wistuba clone, is this color typical of younger/smaller plants or do you think it's just one of those seed grown variations thing?

    I think it's a combination of seed grown variations and growing conditions. My AW clones has always been that dark, even when much smaller. The seed grown was lighter when I received it from Rob and has darkened in my cooler and brighter conditions.

    Not to mention my temperatures as of late have not been falling below 64 at night, which generally limits anthocyanin expression. Under the same photo levels in the winter, I expect to see more color.

    The Wistuba clone that Don and I both have is just a very dark one. It seems to be the fastest one Wistuba has, so that's predominantly what you'll see.

    Interesting! I've never figured that temperature would play much of a role in coloration; just light levels and nutrients.
