The Italian Val is actually V. spiralis (although common names often don't actually match). It is a straight leaved Val that will get to 24" or more. It is a beautiful Val if your tank is deep enough. I am no expert on vals, but I believe the V.american is shorter, and tortafolia, a twisted val, gets to be only about 10". Stay away from anything that says jungle val and has a broad leaf, as they will exceed 3 feet. Sorry I couldn't be of more help. I have a bunch of spiralis that has taken over a 12" deep tank and is covering 2/3 of the surface, although it is only on one side of the tank. It was not what I thought I was buying. It was labelled as jungle val at auction, which it obviously wasn't as the leaves were opnly 1/4" wide, and the plants were short. I thought it was a type I had bought before that only grew, to a height of 10' to 12". Always a risk when buying plants at auction. They should be fine in the 90 when I set it up.
