Campanula ‘Champion White Improved’



Trial: Annual

Year Trialed: 2009

Good Qualities:

Really liked the white variety; In the past we had only grown the blue and pink, the white and lavender were surprisingly popular and were outstanding; Great vase life, very popular form and flower presentation; Beautiful colors particularly the blue and white, long vase live, pleasing flower shape; Color choice and flowers were nice; Outstanding productivity early in high tunnel, attractive flower.


Thrips magnet; Weakest of the Champions trialed, heat stress; Germination wasn’t good and didn’t have many plants to work with, did like what I got, but just wasn’t enough to make a good recommendation; Set back severely by spring weather conditions in field.

Similar Cultivars:

I did not notice any improvement in any of the ‘Improved Champion’ campanulas over the regular ‘Champion’; Other campanulas; All colors of series are alike.


Harvested July week 1 to 3 (planted in field 4/25, Zone 5); We will be adding the white and lavender to our regular plantings from now on, they are worth having in the mix, initial stem was large at 36 inches, 3 others averaged about 15 inches; I should have used support netting; Nice white; Cornell trial yield: 2 stems in field, 9 in tunnel and length: 14 inches in field, 21 inches in tunnel.


I just used water; Cut early in the day, kept cool and also used Floralife, strip bottom foliage before putting into buckets, seems to help with absorption; Water.
