Mikasayama Felt Fern. I found this "compactish" Pyrrosia in a small consignment nursery in Japan. This is where the locals bring their home-grown wares to the nursery and sell them on consignment. One might get some of the best selections from these places, even plants which have never been released to the public. I was thinking that this was a P. lingua, but later found out that it is a separate species, P. hastata, which usually has a three-lobed leaf, but with lobes much longer than this cultivar. One needs to grow in in the garden in shade with a humousy type soil with uniform moisture. It will also do superbly as a container plant as well, especially when one is located in a zone too cold to grow it outside. The last two pictures are curtesy of Longwood Gardens.
