Might have to do with your location I guess. In Europe you see them in every shop that sells plants. They might know them under the name Scindapsus.
Although if you get blank stares when using the latin names I'd say the people arent very experienced in their profession
I always tell customers to give me the latin name of the plant they look for as a lot of plants share the same name in my native tounge, but are very different species.
For example Monstera Deliciosa and Fatsia Japonica, both popular plants here share the same name in my native tounge. Latin names can only ever refer to one specific plant. (As it goes for fish)
