Gardeners' Notes:

Negative anelson77 On May 18, 2009, anelson77 from Seattle, WA wrote:

I inherited this groundcover and it is too rampant for my taste. I have spend 4 years trying to eradicate it as well as the weedy wild morning glories that had taken over the rose garden. After a couple of years of digging them up by the roots whenever they appear the morning glories have given up but not the campanula. If I let it go for a few months it is all over everything as if I had never dug it up.

I haven't seen it spreading to the wild woods though. It likes water and garden conditions a little too well but I don't think it is an ecological threat. Probably ok to plant in places where you really don't want to ever grow anything else, or where you can't get anything else to grow. It is evergreen, freely flowering. I suppose if I didn't dislike it so much I would find it pretty.

Evergreen groundcover native to the northern Balkins. Grows to about 8 inches tall by 36 inches wide with heart-shaped, downy leaves and small, blue funnel-shaped flowers spring through fall with peak in mid-summer.

Plant grows well in Temecula, CA. We do get some frost but doesn't hurt the plant. Great ground cover ~ one that is easily pulled out in areas you don't want it. Not invasive. Highly suggest.

Have planted this in both mottled shade and full shade, with equally satisfying results. As a groundcover, the vibrant green offers vivid contrast in shady areas. The flowers are wonderfully bright, and the plant grows vigorously. A very satisfying ground cover. I combine with Siberian bugloss (variegated) and hardy cyclamen, peonies and heuchera.

Exuberent grower, makes a wonderful groundcover in sun or dark shade, although more floriferous in sun. The flowers are very long lasting and produced over a long period of time.
