Yes Ursula, that's precisely what I'm asking about....I wonder if it works.
Ken, I'm referring to real "moss" and lichen...Spanish moss is tillandsia and it seems to happily cling onto things on my epi-wall somehow....I've never glued it on or anything. I just start with a long strand, drape it over stuff and feed/water it as I do everything else and it turns sortof aquamarine color and gets clingy. I also stick ball moss, another tillandisa that looks like a tangle of spanish moss, onto places and it seems to stick like velcro to some things happily and commit suicide off other things! I have more Spanish moss than I know what to do with, but I love it. It's very mystical looking.
Two plants I mounted today:
A Potinara on a chunk of wood my son spotted in the woods (he has an amazing eagle eye for good mounts)
A mini Phal on pecky cypress:
