Ive seen those at the local supermarket too, and they were labled Stargazers. They smelled like Stargazers, I'm wondering if they are a new cultivar of the Stargazer family.

It depends upon where you get them. I suppose supermarket lilies could be mislabeled. Best to buy from a reputable bulb grower or broker. That way you can get the right one in the unlikely event that you recieve the wrong one in your order.
