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, the species which is spelled differently and is a hybrid, not a pure species.
The plant in my photos will most likely get about three or four times larger, eventually, with a max frond length of about 1″.
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 the rock, with a tiny bit of sand, perlite, and some sphagnum to hold in place and keep it from drying out too fast.
The plant appears to do better when grown a bit more on the wet side, vs just moist. Since increasing water and moisture, it has begun putting more foliage out.
The humidity should be very high, to prevent the delicate foliage from drying out.
