Help - Petunias came back everywhere
Last year I planted 3 small Petunias in the front corner of the bed next to my walkway. These soon filled in nicely to cover the entire corner of the bed, and they flowered all summer and fall. They died in the winter though, so that area was bare. I also had a hanging basket of petunias hanging on my porch.
I was very surprised that this spring the Petunias have come back. The entire corner is covered with petunia's green foliage and its making deep pink flowers already.
I had another surprise though. I have petunias coming up all over in the bed beside my porch. They're coming up in patches in between and under the other plants in that bed. They are flowering already in deep pink, light pink and lavendar. I have never planted any petunias in this bed. Did these come from the hanging basket that was hanging on the porch a few feet away from this bed? The hanging basket contained the same deep pink petunias that I planted by the walkway - no other colors, so I'm not sure how I got other color varities.
I just wanted to ask if petunias usually come back? I thought since they were annuals that I planted in Spring 2005 that I would need to replace them in Spring 2006.
Does a hanging basket of petunias cause patches of petunias to grow in the area the next year? I threw that hanging basket away before the summer was even over last year. This is just my 2nd year of gardening, so I'm still trying to learn how all this works. Please help.
