Plant Summary
Botanical Name: Campanula isophylla
Type: Flowering
Origin: Campanula isophylla originates from the northern parts of Italy.
Height: The stems of the Campanula Plant trail up to a length of around 30 cm (1 ft).
Soil: For this house plant, a good potting mix capable of holding moisture is needed. Potting mixes formulated especially for African Violets tend to work well.
Light: Campanulas like bright, but indirect light. During the winter months, a little direct sunshine will be acceptable.
Humidity: Average levels of humidity keep this plant quite happy.
Temperatures: Preferring slightly cooler conditions, this type of plant prefers temperatures between 7 and 18 degrees C (45 to 65 degrees F).
Water: During the growing and blooming period, the soil should be kept moist, but not soggy, as this will rot the roots. When flowering has ended, the soil should be allowed to dry out a little before the plant is watered again.
Fertiliser: One part of a liquid, balanced fertiliser should be mixed with one part of water and fed to the plant once every 14 days from early spring through into mid to late autumn.
Propagation: Stem tip cuttings may be taken in spring or early in summer and rooted either in moist potting mix or just water to propagate the Campanula.
Description and Care Tips
Campanula Flowers look particularly effective when placed into a hanging basket, on a pedestal, or in a tall, slender pot that will allow the lovely bell-shaped flowers to spill out over the side on their long stems.
Easy to grow indoors, the Campanula isophylla requires nothing but cool air, indirect sunlight and moist soil. Treated right, it will produce masses of white or violet-blue flowers from around mid-summer right into the autumn months. Pinching out spent flowers as soon as possible will encourage new blooms.
Being a perennial, the plant can be kept to grow and flower again for many years. Late autumn or early winter, the stems should be cut back to the base of the plant. Providing the same temperatures and light as the remainder of the year, watering is cut down during the winter months, allowing the soil to become a little drier. Once new growth appears, the usual watering routine can be resumed.
Campanulas need to be repotted when their roots begin to show on the potting mix's surface. This should always be done in winter, or at the latest in early spring. Under no circumstances should this plant be repotted while blooming.
