Adiantum mariesii is an extremely rare, micro fern species, which grows on wet rocks in China. It should not be confused with the more common and much larger Adiantum x mairisii, which is spelled differently and is a hybrid, not a pure species.
It’s hard to see but the new fronds have a lovely yellow green color with a tinge of pink.
This one is tucked in a crevice in a rock. I’m not sure what kind of rock it is, but it seems soft, somewhat like sandstone. I doubt that the type of rock matters.
Inside the crevice is a bit of sand, perlite, and some shredded sphagnum to hold the plant in place and keep it from drying out too fast. I didn’t record the substrate mixture details, but if I had to guess, I’d say it’s ⅓ sand, ⅓ perlite, ⅓ shredded sphagnum.
The plant appears to do better when grown on the wet side, as opposed to just moist. Since increasing water and moisture, it has begun putting out a lot more foliage.
The humidity should be very high, to prevent the delicate foliage from drying out.
The tank in which I’m growing this has a couple of small PC fans to move the air around. I don’t know if that has played a part in my success with this species, but I have a feeling it probably does. The reason I think so is because this fern grows on cliffs in its natural habitat, and cliffs generally have good air flow.
