A cultivar name is given to a very specific looking hybrid or sport, they are patented. If your plant came with a tag that says that, it's possible your plant has lost its' variegation for some reason, or might have had a wrong tag stuck into the pot (erroneously at grower, or accidentally stuck into wrong pot by a shopper who had picked it out to read.) Would you be able to add another pic or two of this plant to this discussion? Somebody should recognize it.
