Campanula

Campanula persicifolia
Campanula persicifolia

Commonly called ‘Bellflowers’ Campanula are a varied group of plants perhaps best known for the ‘Canterbury Bells’ which are Campanula medium.

However their is more to this wonderful group of plants than one species. And although some flowers are indeed distinctly ‘bell shaped’, other varieties are more ‘star shaped’, such as the wonderful C. persicifolia pictured right.

Some are low growing and spreading, some mound forming and others are tall growing varieties reaching over 3ft tall.

Lots of hybrids around, and some garden worthy species as well, however, some can be a little weedy.

General Care

In general Campanulas require a humus rich soil and some moisture during summer. However with so many species growing requirements will differ.

Look for specific growing instructions when purchasing.

  • C. takesimana – This is the Korean Bellflower, attractive mottled pink flowers, HOWEVER it tends to be weedy, and we would not have it in the garden.
