Those are gorgeous! I grew Evening Scentsation petunias from seed and they are very impressive in growth habit (sturdy not long ) and flower production (huge). Will keep growing them every year. The scent really is amazing, as advertised by the seed company.
When I worked for Seed Savers, we grew out their Heirloom Petunia and I remember that scent. Really lovely. :) Here is one of my 'Old Lady Petunia Baskets.' All three are the same and are hanging in the veggie garden. Sorry, I don't remember the exact names - bought them at Farm & Fleet; 2 six-packs, one light, one dark, put 4 plugs in each basket.
