I've never grown this before. Can the blooms be used in cut arrangements? Thanks!
We don't grow this annual. However, the variety Cathedral Bell Series is listed in the cutflower growers seed catalog. It is a zones 9-10 plant.
butterflylion, it's not a good cut flower, the stems the actual flower is on, are quite short. Cathedral Bells are a form of Campanula which isn't a great plant for the combination of heat and humidity we have here :(
I grew 2 plants from seed and they took over the yard. They are beautiful and I did use them in bouquets but the ants were impossible to control and filled every flower though one could not see them until brought in.
If you grow this plant you have to start the seed fairly early, because it takes quite a while to bloom. I grew it last year from seed and it didn't bloom for me. I gave one plant to my mother and she had a couple of blooms before frost. I planted mine in a pot to overwinter in the house and right now it is taking over my breakfast room waiting for the moment it can go outside. Cuttings are extremely easy to start, too - just stick in water and roots show up in no time.
I didn't grow it to use as a cutflower. I try to grow something new each year. I hope I will get blooms soon after it goes outside and gets fed.
