A 4" round terra cotta pot with a large amount an unknown Vallisneria species, probably spiralis.  You are bidding on the pot in the RIGHT side of the photo.  The pot on the left is in another listing.  Use as-is or divide.  The rootball easily slides out of the pot for replanting or dividing into additional pots. This species grows FAST in my hard water under LED shop lights without any supplements, so it couldn't be much easier to grow. Nuisance snails are guaranteed to be included, Chilatherina facitata Clearwater Creek eggs are a likely possibility.
