Almost identical but dwarf
I am familiar with the typical Sansevieria trifasciata, or mother-in-law's tongue. My mother has something very similar and I'm trying to find out exactly what it is. She has at least 2 full pots that needed to be separated when we pulled the plants out of the pots we found they had also been multiplying inside the pots under the roots and dirt, new shoots and babies gallore, I brought some home. It has the same type leaves the only difference is that it is only maybe 6 in tall and is only the dark green color solid. I have checked the internet looking for dwarf and the ones I found are all variegated. Can someone help with the answer.
