Blooming Plants

Campanula spp. (cam-PAN-yoo-la)

Bellflower, Bluebell, Chimney bells, Canterbury bells, Star-of-Bethlehem, Falling stars

This group includes annual, biennial and perennial plants with many forms and uses. The flowers are bell- or funnel-shaped, are 1inch to 2 inches wide and come in loose clusters at the ends of long stems.

Most Campanula varieties are available in violet-blue, purple, pink and white.

Each flower may last only five to seven days, but the plant itself can last for many months with proper care. Only a few flowers usually are open at any given time, meaning that the plant can be in bloom indoors for three weeks or more, and perennial varieties can then be planted outdoors for longer enjoyment.

Campanula are available year-round

Here are some of the more popular species and varieties of Campanulas:
• C. carpatica ‘Blue Ball’ (Tussock bellflower) (purple)

LIGHT Bright, indirect light is best for plants displayed indoors. For outdoor plants, full sun to light shade in the warmest climates is recommended.

WATER Keep the soil moist at all times. Irregular watering and drying can cause bud drop. Avoid standing water.

TEMPERATURE Warm areas (65 F to 75 F) are best for displaying and storing Campanula plants. Do not refrigerate Campanulas because sudden drops in temperature can result in blossom drop, wilt or burn.

HUMIDITY Campanulas benefit from daily misting. Moderate humidity is required.

FERTILIZER Healthy, fertilized plants are more tolerant of insect attacks. Be sure plants are well watered before applying fertilizer, which should be applied at half rate sparingly during the spring and summer. Do not fertilize during the winter.

SOIL Campanulas will do best in an acidic, moist, well-drained soil.

GROOMING Cut these plants back when they have finished flowering to remove straggly stems and faded flowers. Trimming also will stimulate new, healthy growth and additional blossoms.

ETHYLENE SENSITIVITY All Campanulas are moderately sensitive to ethylene gas, and some species are more sensitive than others. Check with your supplier to make sure your plants have been treated with an anti-ethylene agent at the grower level or during transportation.

PESTS Several insects are likely to show up on Campanulas. Check frequently for aphids, thrips, scales, whiteflies and slugs should be checked for frequently.

FAMILY Campanula is a member of the Campanulaceae, or bellflower, family. There are about 70 genera and more than 2,000 species of this family. Relatives include Platycodon (balloon flower), Lobelia and Wahlenbergia.
