Common Names

  • peachleaf bellflower
  • peach-bells
  • willow bell

Taxonomy

Growth

The comparatively fast-growing perennials have a stemless growth and reach heights of 50 to 100 centimetres. The plants reach a width of 30 to 60 centimetres.

Leaves

Campanula persicifolia is evergreen. The dark-green, simple leaves are alternate. They are lanceolate and petiolate with denticulate margins and pinnate venation. The surface of the leaves is glabrous. They turn an attractive yellow in autumn.

Flowers and Fruits

Campanula persicifolia produces racemes of nodding, sky-blue campanulate flowers from June to August. The plants are hermaphroditic.

The perennials produce poricidal capsules.

Root System

The plants form rhizomes.

Distribution

Campanula persicifolia is native to the whole of Europe with the exception of the British Isles, the Caucasus and West-Siberia and is naturalized in the British Isles.

Cultivation

The perennials prefer a sunny to half-shady situation on moist soil. The substrate should be loamy or sandy-loamy soil with a pH between 8 and 10. They tolerate temperatures down to -40°C (USDA zone 3).

Classification after Prof. Dr. Sieber:

  • flower beds (rich soil)
  • open areas with dry to fresh soil
  • woodland borders (soil usually rich in humus)

Uses

The recommended planting distance is 25 to 30 centimetres. Suited for cottage gardens, nature gardens, rockeries, roof greening and for beds and borders, as well as suited as cut flowers and as bee pasture.

Maintenance and Propagation

  • Spreading by self-seeding.
  • Cut back in spring.

Propagate by sowing or by division at the beginning of the growing period.

Pests and Diseases

Honeydew, galls and distorted leaves are a sign for an infestation with aphids. Use an insecticide or control biologically , e.g. with parasitic wasps or predators such as Aphidoletes aphidimyza.

Cankers indicate an infection with fireblight. Generously remove affected parts and destroy them.

A powdery white coat on the plants indicates an infection with powdery mildew. Remove affected plants and apply a fungicide. To prevent infection improve ventilation, keep the roots moist and do not water the plants from above.

White tufts or white covering on the lower surface of the leaves indicates an infection with downy mildew. Remove affected plants and apply a fungicide. To prevent infection improve ventilation, keep the roots moist and do not water the plants from above.

Fine webs on the plants indicate an infestation with red spider mites. These sap-sucking insects mainly appear under glass and can be controlled either with insecticide or biologically with parasitic mites.

Gnaw marks and slime trails indicate a problem with slugs. Prevent infestation by improving hygiene and by regularly working the soil. In case of an infestation use slug pellets or nematodes to control pest. Handpicking the slug also helps, do this preferably in the evening hours.
