Answer: Bellflower is Campanula. These seeds need light and warmth in order to germinate. Sow seeds on the surface of moistened seed starting and press them in, but don't cover with additional mix. Cover the trays or pots with plastic wrap to help hold in the moisture, and place them when they will be warm. Seeds should sprout in 14-28 days when kept at 65F-70F degrees. Remove the plastic wrap as soon as the seeds sprout, or they may develop the fungal disease called damping off.
