Hi, can someone id the plant in the picture for me? It's a long straight stalk with 2 opposing leaves about every half inch or so. It kind of just popped out of the Eco complete one day after I put in some plants that I bought so I guess must be a hitchhiker seed. It's not really fast growing and so far only has this one stalk. Anyone know if it's possible to propagate it and how to do it? I'm guessing it's most likely not a stem plant so cutting it and planting the cutting probably won't work?
