Bailey's Notes
Champion Campanula is a biennial by nature, but has been bred to behave like an annual. It will flower any time days are 12 hours long or longer, which is why you MUST plant them in during the shorter days of the year. This allows them to establish their roots and leaf structure before trying to flower. If you plant them out under long day conditions, they will flower immediately on short stems. For best results plant after Week 40 in the fall, or before Week 10 in the spring. This may require a tunnel in northern climates.
