Campanula kemulariae

by Iza Goroff

Campanula kemulariae is a member of the Campanulaceae, the family which also contains the genera Adenophora, Asyneuma, Codonopsis, Cyananthus, Edrianthus, Jasione, Physoplexis, Phyteuma, Platycodon, Symphyandra, Trachelium, and Wahlenbergia, all of which have valuable rock garden plants, as well as other genera which have not yet found places in rock gardens. The genus Campanula contains about 300 species. Campanula kemulariae is one of many which originate in the Caucasus Mountains.

Campanula kemulariae is a slow, but sure spreader. The spreading plant is low, about 4" (10 cm tall) with shiny, heart shaped, doubly dentate leaves about 2" (5 cm) wide and , putting up suberect (i.e. they flop a bit) multibranched flowering stems, each as long as 12" ( 30 cm). A flowering stem may contain as many as 15 of its lavender-blue bell flowers, each about 0.8" (2 cm) long and 1.25" (3 cm) wide. The flower's long stamen is orange-toned, like a copper bell clapper.

Campanula kemulariae is an easy plant in a wide variety of soils. It is surprisingly shade tolerant. Because of its spreading nature, it is best to keep it from delicate plants. Easily divided, it can also be propagated from seed. It is cold hardy throughout North America.
