Geranium 'Johnson's Blue' | Cranesbill

The Geranium 'Johnson's Blue' offers a delightful splash of color to any garden with its vibrant blue flowers that bloom from May through July. Commonly known as cranesbill due to the shape of its seed capsule, this hardy perennial is cherished for its low maintenance and versatility in garden design.

With its lush green foliage and bushy spreading growth habit, Geranium 'Johnson's Blue' is an excellent choice for borders, group plantings, or edge plantings, adding structure and depth to the garden landscape.

Key Features

The Geranium 'Johnson's Blue' reaches an ultimate height of around 50 cm, making it an ideal candidate for underplanting beneath taller shrubs or as a standalone feature in a smaller garden space.
This Geranium variety is adaptable to a wide range of soil types, provided they are well-drained, and thrives in both sun and partial shade.
Its deciduous foliage remains a vibrant green throughout the spring and summer, offering a pleasing backdrop to the stunning blue flowers that characterize the summer months.

Tips

To ensure the Geranium 'Johnson's Blue' remains vigorous and healthy, consider dividing the plant every few years. This process rejuvenates the plant and encourages more abundant flowering.
Regular watering is needed to maintain its lush appearance, especially during dry spells, as it is not drought resistant.
Although it is a robust plant, overwintering in colder climates may require a layer of mulch to protect the root system from freezing temperatures.
Deadheading spent flowers can extend the blooming period and keep the plant looking tidy throughout the season.

Ideal placement of a Geranium 'Johnson's Blue'

Geranium 'Johnson's Blue' flourishes in locations that offer full sun to partial shade, making it versatile for various garden designs. It is imperative to ensure the soil is well-drained to promote optimal growth and health of the plant. This species adapts to a range of soil types, from loamy to sandy compositions, provided they maintain adequate drainage. The bushy spreading growth habit of this cranesbill makes it an ideal choice for border and edge plantings, where its vivid blue blossoms can fully develop and provide a long-lasting display from late spring through to midsummer.

How do I plant a Geranium 'Johnson's Blue'?

When planting this variety, choose a site that offers full sun to partial shade and ensure the soil is well-drained. The robust root system, cultivated in pots, facilitates successful transplantation and quick establishment in the garden. During the planting process, spacing should be ample to accommodate the bushy spreading growth habit, allowing each specimen to flourish to its full potential, reaching up to 50 cm in height. After planting, provide consistent moisture to support the plant's development, particularly as it adapts to its new environment, but take care not to overwater.

Pruning a Geranium 'Johnson's Blue'

To encourage the bushy spreading growth habit and prolonged flowering of Geranium 'Johnson's Blue', it is beneficial to deadhead spent blooms regularly. This practice can enhance the plant's vigor and may lead to a second flush of flowers later in the season. After the initial flowering period, which typically concludes in July, it's advisable to reduce the entire plant by approximately one-third. This will not only tidy the appearance but also stimulate new growth, possibly resulting in additional blooms. Pruning should be done with clean, sharp tools to ensure clean cuts.

Watering a Geranium 'Johnson's Blue'

To ensure the flourishing of Geranium 'Johnson's Blue', consistent moisture is key, particularly during its peak blooming period from May through July. Aim to maintain even soil moisture, but take care not to overwater, as this species thrives in well-drained conditions. When watering, focus on the base to avoid wetting the foliage, which can lead to issues in dense, bushy plants. During extended periods without rain, increase watering frequency to compensate for the lack of natural precipitation. In contrast, during cooler, wetter spells, reduce the amount to prevent waterlogged soil.

Fertilising a Geranium 'Johnson's Blue'

To ensure the vigorous growth and profuse flowering of Geranium 'Johnson's Blue', it is essential to provide the right nutrients. Fertilization should be done early in the growing season, around March or April, and can be repeated in midsummer to give the plant an additional boost as it enters its peak blooming period. A balanced all-purpose garden fertilizer, preferably one that includes both quick and slow-release nutrients, is ideal for this species.

Apply the fertilizer according to the package instructions, taking care to distribute it evenly around the base of the plant, avoiding direct contact with the foliage. Water thoroughly after applying, to help the fertilizer penetrate the soil and reach the roots. Well-timed and correctly applied fertilizer will support the lush, green foliage and the striking blue flowers that make this plant a standout in any garden setting.

The characteristics of a Geranium 'Johnson's Blue'

Geranium 'Johnson's Blue' thrives when the soil is well-draining and enriched with organic matter, ensuring robust health and vibrant blooms. Deadheading spent flowers promotes further blooming and maintains the plant's tidy appearance. This cultivar's foliage turns a striking red in the autumn, providing an unexpected splash of color in the garden. Additionally, it's known to gently reseed, offering a delightful surprise of new growth in surrounding areas without becoming invasive.

Separating/dividing a Geranium 'Johnson's Blue'

To maintain the health and vigor of Geranium 'Johnson's Blue', division should be carried out every three to four years. The best time to undertake this task is during the cooler months of spring or autumn. Carefully lift the plant from the soil, ensuring all roots are intact. Once removed, inspect the bushy growth and proceed to separate it into smaller segments, each with a good root system and healthy foliage. Replant these divisions promptly, spacing them adequately to accommodate future growth. This method stimulates robust development and ensures a continuation of the species' characteristic blue blossoms.
