Do they seem to be early this year? Clustered bellflower, Campanula glomerata, typically waits until the end of spring to bloom. Once the initial and most prolific bloom phase finishes, sporadic bloom should continue almost through summer. Blue is their most popular and traditional color. White is their second most popular option. Bluish purple and purplish pink are still somewhat rare.
Vegetative growth stays relatively low and unassuming through autumn and winter, and then starts to stand up and get noticed just before spring bloom. Short varieties might bloom without getting even a foot tall, while tall varieties can get two feet tall or a bit taller in partial shade. Each blooming stem supports a dozen or so five-pointed flowers that are about thee quarters to an inch wide.
Clustered bellflower looks neater and probably blooms a bit better as the season progresses if stalks are pruned out as they finish bloom and start to deteriorate. However, a few stalks of some varieties might be retained after bloom to produce seed to scatter elsewhere. Some of the fancier or newer varieties do not produce many viable seed, and such seed may not be true to to type.
I do like the white ones (although blue is the rarer color in the garden). Perhaps it’s your photo that makes them look so particularly appealing too. Really nice.

There were both in the nursery, but I got this picture both because white is less common among bellflower, and because white happens to be my favorite color. However, I appreciate bellflower for providing such a nice rare blue too.

What a beauty. I recognized the genus name, and smiled at the specific epithet. Every time I come across glomerata, I grin. It reminds me of my mother’s love of the word ‘glom’ — as in, “If you leave those meringues stacked like that, they’re going to glom on to one another.”

To me ‘glom’ sounds like ‘globulus’ as in Eucalyptus globulus. It just sounds funny no matter how it is used.

White is my favorite color, but bellflowers are so perfect in blue that I do not know which one I prefer. I suppose it depends on the application.
