Common Names
Common names for Campanula trachelium L. include:
- Nettle-leaved Bellflower
- Bats in the Belfry

- Canterbury Bells
Uses
Campanula trachelium L. has been used for medicinal purposes for centuries. The plant was believed to have diuretic, anti-inflammatory, and anti-rheumatic properties. The root and leaves were used to treat a variety of ailments, including kidney problems, respiratory issues, and joint pain. Today, the plant is primarily cultivated for its ornamental value, and is a popular choice among gardeners.
Appearance
Campanula trachelium L. is a herbaceous perennial that grows up to 1.5 meters tall. It produces numerous light purple, bell-shaped flowers that are approximately 5 cm wide and appear in clusters at the top of the stems. The leaves are long and narrow, with serrated edges and a slightly hairy texture. The plant prefers moist, well-drained soil and partial shade.
Light requirements
The Campanula trachelium L. plant thrives best in a location that receives full sun to partial shade, i.e., about six to eight hours of sunlight in a day. They can tolerate some shade and even prefer it during the hottest part of the day. In full shade, the plant might grow taller, but it might not produce flowers or will have reduced flowering.
Temperature requirements
C. trachelium L. is a hardy perennial plant that can tolerate a wide range of temperatures. It can grow in USDA zones 3 to 8, which means that it can withstand temperatures ranging from -30° to 20° F. During the growing season, the optimum temperature for the plant is between 65° to 75° degrees Fahrenheit.
Soil requirements
Campanula trachelium L. prefers well-draining soil that has a pH of 6 to 7.5. It can grow in various soil types, such as sandy, clay, and loamy soil, but it prefers moist, fertile soil. The soil should be enriched with organic matter, such as compost or well-rotted manure, to boost its fertility.
The plant does not tolerate waterlogged soil, and it is susceptible to root rot. Therefore, the soil should be well-draining. The plant is also sensitive to drought, so watering should be done consistently, but not excessively, to prevent waterlogging.
Cultivation methods
Campanula trachelium L. is a versatile plant that can grow well in a range of soils, including loams, sands, and clays. The plant prefers well-draining soil that is slightly acidic with a pH between 5.5-7.5. It grows best in full sunlight but can tolerate partial shade. This plant can be propagated either through seeds or by division.
Watering Needs
Campanula trachelium L. requires consistent moisture levels, and it is essential to water the soil regularly. However, overwatering the plant can lead to root rot, so it is best to water only when the top inch of soil is dry. The plant should be watered at the base, and it is best to avoid wetting the foliage, which can increase the risk of fungal diseases.
Fertilization
Adding compost or well-rotted manure to the soil before planting can help boost Campanula trachelium L.'s growth. During the growing period, the plant can be fertilized using a balanced fertilizer once every month. It is essential not to overfertilize, as this can lead to excessive foliage growth and reduced flowering.
Pruning
Campanula trachelium L. requires minimal pruning, but cutting back spent flowers can promote new growth and prolong the flowering season. If the plant becomes too large or starts to look untidy, it can be cut back to the ground in late autumn or early spring. However, it is essential to leave a few inches of stem above the ground to mark the plant's location and avoid accidentally damaging it while clearing debris or mulching.
Propagation of Campanula trachelium L.
Campanula trachelium L., also known as nettle-leaved bellflower or bats-in-the-belfry, is a perennial herbaceous plant that belongs to the Campanulaceae family. It is native to Europe and Asia but is commonly found in gardens and landscapes around the world for its beautiful blue-purple bell-shaped flowers.
The following are the methods for propagating Campanula trachelium L.:
Propagation by Seeds
Propagation by seeds is the most common method of propagating Campanula trachelium L. Seeds are sown in a seedbed or in pots during spring. The seeds should be sown on moist soil and covered with a thin layer of soil or vermiculite. After germination, the seedlings can be transplanted once they have established themselves.
It is important to note that Campanula trachelium L. does not always come true from seed, meaning that the characteristics of the parent plant might not be passed on to the offspring. Therefore, this method might result in variations in flower color, size, and shape.
Propagation by Division
Propagation by division is another method for propagating Campanula trachelium L. This method is best done in early spring or fall when the plant is not in flower. The root clump should be dug up and carefully divided into smaller sections, each with some roots and shoots. The new plants can then be replanted immediately in the desired location and watered well.
It is important to ensure that each section has enough roots and shoots to establish itself in the new location, and make sure each section is planted at the same depth as the original plant.
Propagation by Cuttings
Propagation by cuttings is a less common method, but still possible with Campanula trachelium L. The cuttings should be taken in the summer from non-flowering stems. The bottom of the cutting should be treated with rooting hormone and planted in a pot or a well-prepared bed. The soil should be kept moist but not waterlogged. The cutting should root after a few weeks.
Propagation by cuttings is a good way to ensure that the offspring shares the same characteristics as the parent plant.
In conclusion, Campanula trachelium L. can be propagated by seeds, division and cuttings. Each method has its advantages and disadvantages, and the choice of method depends on the conditions and needs of the gardener.
Disease Management
Campanula trachelium L. is generally a hardy plant, but it can be affected by several diseases that can cause significant damage. Here are some of the most common diseases affecting the plant:
- Powdery Mildew: Powdery mildew is a fungal disease that causes a white powdery coating on the leaves, stems, and flowers of the plant. To manage powdery mildew, it is essential to ensure proper air circulation and avoid overcrowding of plants. Additionally, remove and dispose of infected plant parts immediately, and consider using a fungicide.
- Leaf Spot: Leaf spot is a fungal disease that causes small, circular spots on the leaves of the plant. To manage leaf spot, remove infected plant parts, avoid overhead watering, and improve air circulation around the plant. Consider using a fungicide if the infection is severe.
- Crown rot: Crown rot is a fungal disease that affects the base of the Campanula trachelium L. and can cause the plant to rot and die. To manage crown rot, remove and dispose of infected plant parts, improve soil drainage, and avoid overwatering the plant. Fungicides are not effective against crown rot.
Pest Management
In addition to diseases, Campanula trachelium L. can also be affected by pests. Here are some of the most common pests that affect the plant:
- Aphids: Aphids are small, pear-shaped insects that suck the sap from the leaves and stems of the plant. To manage aphids, spray the plant with a strong jet of water to remove them physically, or use insecticidal soap or neem oil to control the infestation.
- Slugs and snails: Slugs and snails are common pests that can cause significant damage to the leaves and flowers of Campanula trachelium L. To manage slugs and snails, use physical barriers, such as copper tape or eggshells, or consider using slug pellets. Additionally, remove any potential hiding places for the pests, such as piles of debris or weeds.
Regularly inspecting the Campanula trachelium L. for signs of pests and diseases can help catch any issues early and prevent them from spreading. Additionally, ensure that the plant is healthy and grown in the right environmental conditions to reduce its susceptibility to pests and diseases.
