My 3rd year wave petunias
Here is a pic of my wave petunias that have re-seeded for the 3rd year. They started out as pink. Each year I get varying shades. I don't do anything special. I crunch the stems and leave them in the pot over winter. This year I added some fresh soil to the pot and a sprinkle of milorganite. I have some supertunias that are coming in to bloom now as well.
