USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).

Tips On Growing Campanula (Bluebells)

Campanula (Bluebells) is a large genus of primarily Old World species known for their showy blue flowers.

Preferred growing conditions:

  • Plant in most any soil including clay with full sun to partial shade conditions.
  • Mulch with most common mulch materials. Mulching not needed in Eastern US.
  • Keep regularly watered and don't let them get too dry.
  • Fertilize lightly in fall with Yum Yum Mix/compost blend.

Special comments:

  • Deadhead to prolong blooming. Leave some seeds to ripen to encourage plants to re-seed themselves.
  • Cut back hard to just above the ground in mid-spring.
