Paul--it looks like Casablanca, but it's not. It's a little to upright. There are so many white Orientals in the market nowadays that it would be hard to say with certainty what it is, really. If you bought these from a grower/seller, I would suggest asking them. If you got them from a big box store, then it was probably labeled as Casablanca but it's strong upright character tends to indicate it's a recent hybrid developed primarily for the cut flower industry. Great looking, either way
