NC State Extension

Campanula ‘Champion Lavender Improved’


Trial: Annual

Year Trialed: 2009

Good Qualities:

Nice soft color (5); In the past we had only grown the blue and pink, the white and lavender were surprisingly popular and were outstanding; Strong stems and large blossoms, customers couldn’t get enough, great vase life with all blooms opening; Long vase live, pleasing flower shape; Flowers were nice; Outstanding productivity early in high tunnel, attractive flower; Loved by all.


Thrips magnet; Heat stress; Germination wasn’t good and didn’t have many plants to work with, liked what I got, but just wasn’t enough to make a good recommendation; Set back severely by spring weather conditions in field; As apical flowers fade, they shrivel and brown without dropping, thus reducing quality of appearance, even though the subsequent flowers look beautiful.

Similar Cultivars:

Other campanulas; All colors of series are alike.


Harvested in 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 stems were large at 36 inches, 3 others averaged about 15 inches; New color for us, nice; A “must grow”; I should have used support netting; Cornell trial yield: 2 stems in field, 10 stems in tunnel and length: 13 inches in field, 22 inches in tunnel.


I just used water (2); Cut early in the day, kept cool and also used Floralife, strip bottom foliage before putting into buckets, seems to help with absorption; Cut early in bloom cycle.
