Glad you like the Sphagnum. It is a mix of plants, no idea what species. (Don't know, don't care: as someone pointed out, there are well over 100 species, and identification in cultivation requires skill and intimate knowledge of the genus, so why try?) Most of it came from Hortus Botanicus (what the heck happened to Robert??) as packing moss accompanying purchased plants, and some from Jeremiah, and some came from spontaneous colonies that generated from chopped, dried moss used for Nepenthes seed germination cultures. The stuff from HB grows very red at times of the year (some pots are a mix of bright green and dark red right now, and yet are all the same plant!) but mainly stays green or green-brown. Getting Sphagnum to consistently grow red likely requires serious witchcraft, the likes of which few of us can summon.
@Sundrew: re better beards. Agreed. And DJ has told me the next time we meet, she will wear a prosthetic chin wig, to feel more in sync with the group. I can tell you, that is something I am looking forward to!
@mass: I am pleasantly surprised by my Cephaloti (plural?), since this is my first experience growing the genus, and I expected more trouble than I got. Mind you, until I have gone another four or five years, I don't consider myself genuinely successful with them: still just "an accomplished novice".
@Brie: another time, another time. It will only get better!
