I don't profess to know every rosemary (Salvia rosmarinus) there is, but it's a distinctive plant, generally. That doesn't resemble any rosemary I've ever seen. Plus, even the smallest rosemary seedlings have a distinct scent.
I think you got fed a tall tale ☹️ . Apologies, I can't offer any better suggestions than Tiffany.
