I winter sowed these seeds and it seemed they all came up. I was so pleased. The seeds were a trade labelled campanula blue bellflower. I planted them in the garden in late April and they really took off. I was so pleased. Then they bloomed. They have a tubular shape to the flower head and a very small white or light pink flower. Here is a picture. Are they really 'campanula blue bellflower' ?? There is cosmos in the background
