Amazon Sword or Java Fern. I have never seen Petsmarts selection. Petco usually has some decent Amazon Swords and Java Ferns available. And you can buy them either small, medium, or large. Just remember they will grow. Root tabs are suggested.
stay away from anything you are not sure about, or seems like a non aquatic plant. Both Petco and PetSmart are notorious for selling non-aquatic plants as aquatic plants. I fell for it once.
But honestly your plastic one looks like an Amazon Sword. I have a group of them in my tank.
Whoops sorry, I didn't see that you did not want a live plant. I think you should give one a try :)
