The first Campanula that behaves as an annual (although the rest of its species are biennial). People have trouble with this crop because it has a strong day length response. Below 12 hours of daylight it remains vegetative, and above 12 hours it initiates bud, regardless of how established it is. (Hence the talk of it flowering in the plug tray, or on 2" stems when planted too late in the season) Early planting is recommended to let it establish before natural day length triggers flowering. It would be worth experimenting with blackout fabric to provide long nights (thus short days) until the plant has bulked up enough to support long stem growth. This crop would be best grow in the tunnel for northern growers, as your ground may otherwise be frozen at the ideal planting time.
Best results will occur if planted before mid March (week 10 or 12)
Many folks succeed with a fall transplant in mild winter areas, or northern areas with good snow cover.
