I have veronica speedwell (Crater Blue) which was planted when I first began gardening (at least 5 years ago). There were flowers the first year at the time it was planted, but I have not had blooms on it since. I have tried moving it to different spots. We fed with Miracle Grow. Nothing. Any suggestions? Everyone I talk to or web sites I have visited love veronica and talk about the flowers, but how can I get some?
