Here is the charming hotpot that I could admire this Sunday. This is a seedling of Viola hederacea (Research Bay) in a potting soil with micorhizal fungi.
is it possible to determine this fungus? the 2 species seem to live very well together, but I can not be sure that they are in symbiosis ...
As I have seeds of Bletilla striata, and of Spiranthes cernua, I could perhaps try to sow them with this potting soil?
