Campanula glomerata 'Superba' | Clustered bellflower

The Campanula glomerata 'Superba' is a captivating perennial known for its vibrant display of blue-purple blossoms that make it a standout in any garden. Commonly referred to as the Clustered Bellflower, this plant's charming flowers group together at the top of sturdy stems, creating a visually striking effect. Perfect for borders and group plantings, it brings a touch of wildflower beauty to cultivated spaces.

This species thrives in a variety of soil types, provided they are well-drained, and is partial to sunny or semi-shaded locations, making it a versatile addition to your garden.

Key Features

The Campanula glomerata 'Superba' is celebrated for its generous clusters of bell-shaped flowers that bloom in the summer months of June and July.
Its flowers boast a radiant shade of purple, which is particularly striking against the lush green foliage that remains vibrant throughout the spring, summer, and autumn seasons.
With an upright growth habit, this plant reaches an ultimate height of approximately 50 centimeters, making it an ideal choice for adding structure and height to garden borders.
Though it is deciduous, its seasonal appearance is eagerly anticipated each year for the burst of color it provides.

Tips

To maintain the health and vigor of your Campanula glomerata 'Superba', consider dividing the plant every few years. This process rejuvenates the plant and stimulates robust growth.
The ideal time for division is during the cooler months of spring or autumn. Carefully lift the plant from the soil, divide it at the root, and replant the sections with ample space to flourish.
Regular watering is essential, especially during dry periods, as the 'Superba' is not drought-resistant. Submerge the soil around the roots to ensure it receives adequate moisture.
Deadheading spent blooms can encourage a longer flowering period and prevent the plant from expending energy on seed production.

Ideal placement of a Campanula glomerata 'Superba'

For optimal growth, Campanula glomerata 'Superba' should be situated in a location that enjoys full sun to partial shade. The area should be able to accommodate the plant's upright growth habit and allow for its potential height of 50 cm. Thriving in all soil types, the key is ensuring the soil is well-drained to prevent waterlogging, which this species does not tolerate well. Regular watering is necessary, particularly during dry spells, as the plant is not drought-resistant. A position that provides the right balance of sunlight and moisture will showcase its striking purple blooms in their full glory during the summer months.

How do I plant a Campanula glomerata 'Superba'?

To plant Campanula glomerata 'Superba', begin with well-drained soil that accommodates all types, ensuring optimal drainage and aeration for the roots. The plant thrives equally well in full sunlight or partial shade, offering flexibility in garden placement. Being pot-grown, it can be introduced to the garden throughout the growing season, avoiding periods of frost. Upon planting, water thoroughly, submerging the soil to encourage root establishment. This species will require regular watering to maintain soil moisture, as it does not exhibit drought resistance. The upright growth habit of this plant will reach its full height of 50 cm, adding a vertical dimension to borders and group plantings.

Pruning a Campanula glomerata 'Superba'

Pruning is an essential aspect of care for Campanula glomerata 'Superba' to encourage a more prolific blooming period. After the initial flowering in early summer, it is advisable to deadhead by removing spent flower stems. This not only tidies the appearance of the plant but can also stimulate a second, albeit less abundant, flowering period. As a deciduous species, it will lose its foliage in winter. Pruning should be done post-flowering, cutting back the foliage to the ground level to promote healthy growth in the spring.

Watering a Campanula glomerata 'Superba'

For the Campanula glomerata 'Superba', ensuring consistent moisture is key to maintaining its vibrant blue and purple blooms. This species thrives when the soil is kept evenly moist, which can be achieved through a method called submerging. This involves watering deeply, allowing the water to fully saturate the root zone, promoting a strong and healthy root system. During periods of drought or particularly hot weather, increase the frequency of watering to compensate for the higher evaporation rates. However, despite its need for regular moisture, it is crucial to avoid waterlogging by ensuring that the soil is well-drained.

Fertilising a Campanula glomerata 'Superba'

To promote vigorous growth and enhance the striking blue and purple blooms of Campanula glomerata 'Superba', it is essential to provide adequate nourishment. Fertilization should commence in early spring, as new growth appears, using a balanced, slow-release fertilizer that will provide consistent nutrients throughout the growing season. Care should be taken not to over-fertilize, as this can lead to excessive foliage at the expense of flowers.

A second application of fertilizer may be beneficial just before the onset of the flowering period in June to support the plant's energy needs during blooming. Always follow the manufacturer's instructions for dosage and application methods. After fertilizing, ensure the soil is well-watered to help distribute the nutrients to the roots, especially if the plant's water requirements indicate submergence.

The 'Superba' variety adds a touch of elegance to borders and cottage gardens.

Separating/dividing a Campanula glomerata 'Superba'

To propagate Campanula glomerata 'Superba' effectively and ensure its ongoing health, division is a recommended practice. This process, ideal in spring or autumn, involves carefully lifting the plant and separating it into smaller sections.
