Also known as the ‘clustered bellflower’, Campanula glomerata comes in a number of varieties that are well suited to growing in the perennial border or cottage garden.
As the common name predicts the flowers form in clusters atop stem in spring to summer. The species has a slow spreading suckering habit but is not invasive in our garden.
Flowers are useful for cutting, especially the taller varieties. The lower growing types are suitable for planting between small upright shrubs and roses.
- Campanula glomerata will reach around .5m with violet purple flowers.
- Campanula glomerata ‘nana’ is lower growing to around 20cm.
- Campanula glomerata ‘Crown of Snow’ has attractive white flowers on tall stems to around 50cm.
- Campanula glomerata ‘superb’ purple to blue flowers to .5m, similar to the species.
All varieties prefer a humus rich moist but well drained soil. Propagation is easy from basal cuttings or divisions taken in spring. Place newly divided clumps in a cool position and keep moist until new growth begins and indicates a strong root system.
Best position in in full sun, however we do suggest some protection from the heat of the afternoon sun as our climate is warmer than the natural habitat.
