Hi I'm growing what was supposed to be kentucky old fashioned petunias this year but I don't notice them any more fragrant than other types. Do I have the wrong kind? Some descriptions say the old (kentucky included) types of petunia have a rich "jasmine like" perfume. Has anyone else grown the real heirloom types? What do you think? If you found a good source of really fragrant ones let me know. Thanks :)
