Campanula glomerata 'Alba' | White clustered bellflower

Campanula glomerata 'Alba', commonly known as the white clustered bellflower, is a charming addition to any garden border. Its pristine white flowers, tightly clustered at the stem's apex, bloom profusely in the summer months of June and July, creating a focal point of tranquility and grace.

This perennial plant is favored for its upright growth habit and ease of care, making it a perfect choice for both novice and experienced gardeners alike.

Key Features of Campanula glomerata 'Alba'

The Campanula species is renowned for its showy blooms, and 'Alba' is no exception, offering a display of radiant white flowers that stand out against the green foliage.
It thrives in a range of well-drained soils and is adaptable to both sun and partial shade, making it a versatile addition to various garden settings.
While it is not evergreen, the plant's foliage remains a vibrant green from spring through autumn, providing a lush backdrop for the summertime blooms.
Reaching an ultimate height of 60 cm, Campanula glomerata 'Alba' fits perfectly in garden borders and group plantings, where its upright growth habit can be fully appreciated.
This species does not bear fruit and requires submerging for water, ensuring the soil remains consistently moist for optimal growth.

Tips for Growing Campanula glomerata 'Alba'

Regular watering is crucial for the white clustered bellflower, particularly during dry periods, as it is not drought-resistant.
To encourage healthy growth and rejuvenate the plant, propagate by division in spring or autumn. This method ensures the vitality of your 'Alba' and allows you to spread its beauty to other areas of your garden.
When planting in borders or groups, space the divisions adequately to allow for proper air circulation and light penetration, which will foster a robust and full display of flowers.
Although minimal maintenance is required, removing spent flowers can promote a second bloom and extend the flowering period of your Campanula glomerata 'Alba'.

Ideal placement of a Campanula glomerata 'Alba'

This species thrives in locations that offer full sun to partial shade, ensuring ample light for optimal blooming. While adaptable to all soil types, it is imperative that the soil be well-drained to prevent waterlogging, which the plant does not tolerate well. To achieve the best growth and flowering results, position the plant where it can bask in the morning sunlight and receive some afternoon shade, particularly in hotter climates. Proper site selection will reward with a profusion of white blossoms, enhancing the beauty of borders and group plantings.

How do I plant a Campanula glomerata 'Alba'?

For optimal growth, Campanula glomerata 'Alba' should be planted in well-drained soil, which can support a variety of soil types. Position the plant in a location that receives full sun to partial shade to encourage a profusion of its striking white blossoms during the summer months. During the planting process, ensure the root ball is fully submerged to facilitate adequate water uptake. This species, with its upright growth habit, will reach an ultimate height of 60 cm, creating an elegant presence in borders and group plantings. It's important to provide regular watering to maintain soil moisture, as this plant is not drought-resistant.

Pruning a Campanula glomerata 'Alba'

To maintain a neat appearance and encourage a second bloom, it is advisable to deadhead the spent flowers of Campanula glomerata 'Alba' throughout its blooming period. Once the flowering has ceased, cutting back the stems can help rejuvenate the foliage and compact growth for the following season. In autumn, as the plant prepares for dormancy, remove any old foliage to keep the area tidy. This species requires minimal pruning and benefits from the occasional tidying to sustain its vigorous and upright growth habit.

Watering a Campanula glomerata 'Alba'

The Campanula glomerata 'Alba' thrives with consistent moisture and should be watered thoroughly to ensure the soil is sufficiently damp. Given its preference for well-drained soil, care should be taken to avoid waterlogging, which can be detrimental to its health. During the active growth months, especially if the weather is dry, it may be necessary to water the plants more frequently to maintain the necessary moisture levels. Potted specimens will require more frequent watering than those in the ground, as pots can dry out rapidly. It is paramount to establish a regular watering schedule, particularly for plants in sunnier locations.

Fertilising a Campanula glomerata 'Alba'

To support the vigorous growth and abundant flowering of Campanula glomerata 'Alba', it is advisable to fertilize the soil in early spring before the onset of new growth. A balanced fertilizer, rich in all essential nutrients, is ideal for this species. As the plant prepares for its blooming season in June and July, an additional dose of fertilizer can be applied as a top dressing to sustain its energy needs.

The well-drained soil should be enhanced with the fertilizer, ensuring that it is evenly distributed around the base of the plant to avoid direct contact with the foliage and roots. Regular monitoring of soil moisture is crucial, and watering should be done thoroughly, allowing the soil to be fully saturated, to facilitate the proper uptake of nutrients by the plant.

The characteristics of a Campanula glomerata 'Alba'

The Campanula glomerata 'Alba' is a delightful addition to any garden space with its elegant white blooms. This species thrives in a range of soil types, provided they are well-draining. It's worth noting that the plant's clump-forming nature makes it an excellent candidate for creating a dense floral display in borders and beds. For optimal blooming, deadheading spent flowers encourages a second flush of blossoms, extending the visual enjoyment throughout the growing season.

Separating/dividing a Campanula glomerata 'Alba'

For a thriving display, division of this species is recommended every few years to maintain its health and vigor. The ideal times for division are during the cooler months of spring or autumn. Begin by gently lifting the plant from the soil, taking care to preserve as much of the root system as possible. Once removed, carefully separate the plant into smaller sections, ensuring each has a portion of the roots and foliage. Replant these divisions promptly, spacing them adequately to accommodate future growth. This practice not only rejuvenates the plant but also helps control its spread within garden borders.
