How to Take Care of a Campanula Flower?

Overview

Campanula flowers (Campanula spp.) are a group of flowering perennials native to the Northern Hemisphere. Also known as bellflowers, these plants are highly desirable for their large, bell-shaped flowers that come in shades of blue, purple, pink and creamy white. The size of the plant varies between only 4 inches tall and over 4 feet tall, depending on the species and cultivar, with a maximum spread of 3 feet. Campanula flowers are hardy to United States Department of Agriculture zone 3 and are low-maintenance plants, according to the University of Illinois.

Step 1

Choose a sunny or partially shaded area for your campanula flowers. Well-draining soil is best for these plants, according to the University of Maryland, so avoid planting in a depression or where standing water collects.

Step 2

Sow campanula seeds early in the spring, when there is no danger of frost. Place the seeds between 12 and 18 inches apart, and cover them with a fine layer of soil.

Step 3

Water at least once a week. While these plants can tolerate brief periods of drought, according to the University of Illinois, they grow best when the soil is kept moist.

Step 4

Feed your campanula flowers with a balanced (10-10-10), all-purpose fertilizer in the spring when growth appears and again in the summer when the first flush of flowers has faded.

Step 5

Deadhead (remove spent flowers) frequently to encourage re-blooming. If properly deadheaded, campanula flowers will bloom from spring clear through the end of summer.
