    Healthy and good size. Out all the plants that I put in my aquarium, this one melted to nothing and hasn't come back. Not the seller fault. The shock of different aquarium conditions can cause plants to melt.

    This lobelia grows wild where I live, I had no idea it could be aquatic.

    Received two small stems. However, they were very nice looking with huge roots.
