The remarkable Eryngium planum 'Blauer Zwerg', commonly known as blue eryngo, is a captivating perennial that brings a touch of striking blue to any garden setting. With its steel-blue flowers and greyish-green foliage, this plant is a favorite among gardeners looking to add texture and color to their borders or group plantings.

Key Features

Eryngium 'Blauer Zwerg' boasts an upright to bushy growth habit, providing structure and interest to garden compositions.
This variety reaches an ultimate height of approximately 60 cm, making it an ideal choice for mid-border placement.
The blue eryngo's foliage begins as green in the spring and maintains its vibrancy throughout the summer and autumn months.
Flowering in July and August, the plant's blue blooms are a veritable magnet for pollinators, enhancing the biodiversity of your garden.
While it is not evergreen, the 'Blauer Zwerg' is drought resistant and has average water needs, making it a suitable candidate for gardens with less frequent rainfall.

Tips

To encourage healthy growth and propagation, the 'Blauer Zwerg' can be divided in the spring or autumn. This not only leads to an increase in plants but also ensures that your specimens maintain their vigor.
When planting, choose a location that receives full sun, as this will maximize the intensity of the flower's color and support robust growth.
Although the plant is adaptable to various soil types, it thrives best in well-drained conditions, so be sure to prepare the planting site accordingly.

Ideal placement of a Eryngium planum 'Blauer Zwerg'

Thriving in full sun, Eryngium planum 'Blauer Zwerg' is best positioned where it can bask in unfiltered daylight for the majority of the day. This species is adaptable to various soil types as long as they are well-drained, making it a versatile choice for gardeners. Its tolerance for drought and preference for open, sunny spots make it an ideal candidate for xeriscaping or rock gardens. When selecting a location, ensure ample space for its upright to bushy growth habit, allowing this striking plant to reach its full potential of 60 cm in height.

How do I plant a Eryngium planum 'Blauer Zwerg'?

To achieve optimal growth, these perennials should be situated in a location that receives full sun, which is integral to their development. The soil must be well-drained, yet this species is adaptable to various soil types. When planting, ensure there is adequate space between each specimen to accommodate their upright, bushy growth and eventual height of 60 cm. Post-planting, water the plants moderately to establish them in their new environment. It's beneficial to plant in spring or autumn, which provides a conducive setting for root establishment before the extremes of summer heat or winter cold.

Pruning a Eryngium planum 'Blauer Zwerg'

Eryngium planum 'Blauer Zwerg' benefits from occasional pruning to promote vigorous growth and maintain an attractive form. Deadheading the spent blooms after flowering in July and August can encourage a tidier appearance. Pruning is generally minimal; cut back the previous year's growth to the ground in early spring before new growth begins. This will allow the plant to concentrate its energy on producing a fresh flush of its distinctive blue and grey foliage and vibrant blue flowers each summer.

Watering a Eryngium planum 'Blauer Zwerg'

While Eryngium planum 'Blauer Zwerg' is drought-resistant, it thrives best with consistent moisture during its growing season. During prolonged dry spells, ensure the soil is kept evenly moist to maintain its vibrant blue blooms and striking foliage. Watering should be done deeply to encourage a robust root system, but always allow the soil to dry out slightly between watering sessions. Overwatering can be detrimental, as this species prefers well-drained conditions. Regularly checking the soil moisture will help establish an optimal watering routine for this resilient yet exquisite plant.

Fertilising a Eryngium planum 'Blauer Zwerg'

To promote a robust display of the striking blue blooms and maintain the vigor of Eryngium planum 'Blauer Zwerg', proper fertilization is key. Apply a balanced, slow-release fertilizer early in the spring to support the initial flush of growth, and then again just before the onset of the flowering period in July.

As this species is tolerant of a range of soil types, it does not require heavy fertilization; a moderate application will suffice. Ensure that the fertilizer is worked gently into the soil surrounding the plant, taking care not to disturb the root system. Adequate fertilization not only enhances the ornamental qualities of the plant but also strengthens its overall health, enabling it to withstand various environmental stresses.

The characteristics of a Eryngium planum 'Blauer Zwerg'

Eryngium planum 'Blauer Zwerg' is highly esteemed for its resilience and low maintenance requirements. Its striking steel-blue bracts and cone-shaped flowers add an unusual texture to garden compositions.

The 'Blauer Zwerg' cultivar, with its compact form, is particularly well-suited for smaller gardens or as a border plant, offering a unique aesthetic without overwhelming the space.

Separating/dividing a Eryngium planum 'Blauer Zwerg'

To propagate and rejuvenate Eryngium planum 'Blauer Zwerg', division is an effective method that should be performed during the cooler months of spring or autumn. Carefully lift the plant from the soil, ensuring you retain as much of the root system as possible. Once removed, the plant can be divided into smaller sections with a sharp knife or spade, making sure each division has a portion of roots attached. Replant the divisions promptly, spacing them adequately to accommodate their bushy growth habit. This process stimulates robust new growth and maintains the health and vigor of this distinctive blue-flowered species.
