A few years ago, I found a field of petunias and fell in love with their heartiness. Follow this link to see the petunias I found in an abandoned lot. Last year we had a flowerbed here with azaleas, so I planted petunias too. They grew well, even in full sun. Our privacy fence was replaced and the flowerbed and azaleas removed, but look what keeps popping up! Sometimes the lawn service mows them down, but they keep popping back up.
