Gardeners' Notes:


On Dec 12, 2014, coriaceous from ROSLINDALE, MA wrote:

One of the longest bloom displays of any small campanula, especially if deadheaded. A vigorous trailing habit, but it has not inherited the aggressive or invasively spreading propensities of its parent C. portenschlagiana. Best if divided every other year.

The Royal Horticultural Society gave this plant its coveted Award of Garden Merit. The Elizabeth Cary Miller Botanic Garden selected this for their Great Plant Picks program for the Pacific northwest.

Introduced by Walter Ingwersen.

I just purchased these cute little flowers, but I'm wondering if they spread out of control or if they stick to the described habit of spreading about 12" wide. I really don't want it to invade everything. Can someone chime in with their experience?? Thank you!

This plant is blooming its little heart out in the garden and has been since the last part of May. The flower color is a clear and crisp lilac-blue. It has been a trouble free plant for me, although I have been told that slugs and snails will feast on it. If that were true I am sure they would have done it by now.

There is much about this plant to bring joy to the heart of anyone who sees it. However, if there is one thing they could improve about this plant is to make it stand up to being rained on better. On sunny days the little bells dance at the end of their stem in the lightest breeze. Today, in the rain, they are prostrate. A plant that brings such joy to your heart should not have to suffer having its face to the cold ground.

This hybrid combines the best qualities of its parents, the Dalmatian and Serbian Bellflowers. Plant habit is half-ways between both parents. Lovely display and very floriferous.
