Well, since Incense is a hybrid that can only be propagated via cuttings, either your seeds are an "Incense x" hybrid or the folks who sold them to you are clueless.

Varigration is fairly common among the decaloba types, less so among the larger flowering species. What do the leaves actually look like? Do they appear in the five-pointed Incense form? Leaf form is quite variable amongst passis, so it's tough to tell without more information.
