In 2003 I purchased several packs of these and planted them in window boxes on my deck. They all grew like crazy. At the end of the season, the seed pods were EVERYWHERE. The next season, I had an INVASION of these petunias as they started growing everywhere under my deck, in old containers, even in other areas of the yard.
Even this year, they are still coming back.
This leads me to great confusion as to why merchants are charging **35 CENTS PER INDIVIDUAL SEED**. Initially I thought it must be a hybrid that doesn't put many seeds out, but of course now I know this is wrong.
These vendors don't charge these high prices for their other petunia seeds like "celebrity."
