Howdy! I have had this rosette plant growing in my propagation tank for a while. I first thought it was val. americano or dwarf sag with a disease, but I let it go just to see what would happen, and it spread via runner into identical rosette plants. It's grassy looking with rusty tiger stripes as you can see below. runners go below the substrate and come up to make new rosettes unlike dwarf sag. Any ideas?
