It doesn't have a bulb. I did a bit more research and I believe that you are correct. I have it on the side of my tank. I think I will move it to the background when it gets a bit larger.Thank you.I don't think it is either. To me it looks like Cryptocoryne crispatula var. Balansae. And if I'm wrong , then it's Crinum natans (Crinum aquatica) which should have a bulb-like root that should be planted ~1/2 out of the substrate.
