Which species of bellflower are hardy?
The bellflower - the botanist calls it Campanula - is a popular and very lush flowering ornamental plant that thrives almost everywhere: in the garden under woods, in the rock garden, on dry stone walls as well as on the balcony or on the windowsill in the living room. However, their purpose depends strongly on the desired bell flower species, because these differ in terms of their needs and claims in some cases significantly from each other.

This is especially true with regard to winter hardiness, because the individual species of bellflower are almost everywhere from the Arctic to the Mediterranean climates. Of course, they also prefer a location and hibernation that best suits their natural environments. So if you live in a rather cold area of Germany and want to plant bellflowers in the garden, then you better choose a little frost-sensitive species. These are originally often from the high mountains, v. a. the Alps.
Bluebell species and their hardiness
In the following table we have compiled some of the most popular bellflower species as well as their winter hardiness.
Do not just pay attention to the frost hardness
However, those who wish to overwinter bellflowers should not just go for the frost sensitivity of the plants. Most species of the Campanula are perennial shrubs that, although their shoots freeze in winter, re-expel from the overwintering rhizomes in spring. Other species, on the other hand, are only one to two-year-old bellflowers that need to be sown again and again. Among them is the Marien bellflower, which is very popular especially as a cut flower, which basically only has to survive a single winter.
