Sorry, but it sure sounds like it was mislabeled. What do the leaves look like on the CG? Can you post pix so we can help you out easier?

OK, here's some pics of my possible Datura buds.

And these were the first 2 blooms on my Santa Rosa. Can't wait for more.

That looks like a brug. Many will have buds that start out pointing upwards but will become pendulous as they mature. Not all brug hang straight down like your Santa Rosa. Some kind of stick out to the side but none face upwards like daturas.

Def a brug. You said you had blooms..like Karyn said, alot of brug buds will start out pointing up.
Santa Rosa look good, very nice :)

If you say it's a Brug then it must be. It's interesting that the buds are so different but then I don't have much experience to draw on. I'm really anxious now to see what these blooms will look like. I've also got a NOID that someone sent me late last summer. It's gorgeous and tall and full but absolutely no signs of a bloom. :( I keep watching and waiting though!
I should also mention that this is the BEST forum on Garden Web. Y'all are always willing to help. Thanks!
