There are plenty people on Etsy selling petunia seeds for things like "red star" or "rose star" petunias, or "double madness red white" or "purple pirouette". A couple people were selling live plants of the "night sky" petunia series but I think they may all be sold out now. Park Seed are also good for petunia seeds www.parkseed.com
You can always try calibrachoas as a fun alternative to petunias.
Then there is always Burpee https://www.burpee.com/flowers...
Or Proven Winners: https://www.provenwinners.com/...
Thank you!
They have nice things, I seen alot of stuff from Proven Winners, those are nice. Our lowes carries some PW but they sell fast and they don't have alot of variety.
They do but their shipping is high and they are always out of what I want! I have ordered other plants from them before and they send nice healthy plants, well packaged. Was pleased w my order.
