These long blooming perennials are a great source of late spring and early summer color. The Bells series provides a spectacular floral show over dense mounds of green foliage. Use these plants to line borders or in mass plantings for a head turning display.
Dark violet-blue flowers. Very upright. Later to bloom than other C. glomerata.

A member of GROUP 1:
This group of Campanula grows best in fertile soil with a neutral to alkaline pH. Lime can be added to the soil to obtain these conditions. Keep the soil moist but make sure it is well-drained.
Members of this group will grow in either full sun or partial shade, though some shade is recommended in areas with very hot summers. The delicate flower colors are best preserved with some shade. Taller varieties may require staking.
Cutting the plants back hard after flowering will keep them more compact and will help to prevent self-seeding. This action may also result in a second flush of blooms.
Container:
Trade 1 Gallon Container
When to Plant:
Late winter to spring.
Finish:
8-10 weeks
Container:
Trade 1 Gallon Container
When to Plant:
Midsummer
Finish:
7-9 weeks
Growing Temperature:
65-70° F
Holding Temperature:
50-60° F
Soil PH:
5.8-6.2
EC (What is EC?):
1.0-1.2 pour through method
Fertility:
Apply a constant liquid fertilizer program, 75-125 ppm at each watering. For Controlled Release or Slow Release Fertilizer, see your preferred supplier for recommended rates for incorporation or top dressing, as it varies by fertilizer.
Vernalization:
Cold required for 10-15 weeks at temperature below 40° F.
Pests & Diseases:
Aphids, onion thrips, slugs, snails, western flower thrips, spider mites, aster leafhopper, leaf and root-knot nematodes.
Crown rot, rot (Sclerotium), impatiens necrotic spot virus, aster yellows, leaf spots, powdery mildew, root rots, rust, damping-off, Botrytis blight, Verticillium wilt.
Potting & Timing:
Plant large vernalized plugs in early spring.
Small plugs are commonly potted in the summer of the year prior to sales.
Moisture:
For potting soil use commercial planting media.
Planting Level:
At crown level.
PGRs/Pinching:
May not be required. One or two 2,500 ppm applications of Daminozide (B-Nine or Dazide), seven days apart, can be effective at reducing plant height when applied just as the flower stems are beginning to elongate.
Lighting:
Long days required for flowering.
Other Comments:
Research has shown that most campanula cultivars display better quality characteristics, such as a higher bud count and flower size, when grown at cooler temperatures.
