Hi Cheryl,
I bought the seeds from Park Seed last year, but they are probably available from other seed companies, too. Just search for Petunia superbissima Wine Red. I believe GeoSeed offers a similar one called Ruffly Double Wine. I've sown that one before too and I don't think there is much difference, if any.
They were very nice. I like Petunia superbissima varieties. All those ruffles.
