Astrantia ‘Magnum Blush’ thrives in soil that is consistently moist but not waterlogged. Adequate watering is essential, especially during the plant’s active growth periods and particularly during dry spells. It is crucial to maintain a balanced approach to watering, ensuring that the soil remains moderately moist without becoming excessively soggy, which can lead to root rot and other moisture-related issues.


In terms of sunlight requirements, Astrantia ‘Magnum Blush’ prefers partial shade to full shade. While it can tolerate some morning sun, especially in cooler climates, it generally performs best in locations with dappled sunlight or partial shade. In hot summer regions, providing the plant with protection from intense midday sun is beneficial for its overall health and vigor.


Astrantia ‘Magnum Blush’ benefits from periodic fertilization to support steady growth and abundant flowering. A balanced, slow-release fertilizer can be applied in early spring as new growth emerges. It is important to follow the manufacturer’s recommendations regarding application rates and timing to prevent over-fertilization, which can negatively impact the plant’s health.


The greater masterwort thrives in humus-rich, well-drained soil with a slightly acidic to neutral pH. Amending the soil with organic matter such as compost or well-rotted manure can enhance its fertility and structure, providing an optimal growing medium for Astrantia ‘Magnum Blush’ to flourish.


Pruning plays a vital role in maintaining the health, appearance, and longevity of Astrantia ‘Magnum Blush.’ Deadheading spent flowers not only promotes continuous blooming but also prevents the plant from self-seeding prolifically. Additionally, removing any yellowing or damaged foliage can enhance the plant’s overall aesthetics and reduce the risk of disease. Pruning should be carried out with sterilized tools to prevent the spread of potential infections.



Propagating Astrantia ‘Magnum Blush’ through division is a reliable method to create new plants and rejuvenate existing ones. This can be done in early spring or early autumn by carefully dividing the plant’s clumps into smaller sections, each containing healthy roots and shoots. These divisions can then be replanted in suitable locations, where they can establish and flourish.

Seed Sowing

Growing Astrantia ‘Magnum Blush’ from seeds can be an engaging and rewarding process. Sow the seeds in a well-prepared seed-starting mix in early spring, maintaining consistent moisture and moderate warmth to encourage germination. Once the seedlings have developed into sturdy plants, they can be transplanted into their permanent growing positions.

Container Popularity

Astrantia ‘Magnum Blush’ is well-suited for container cultivation, making it an excellent choice for gardeners with limited space or those seeking to add a touch of elegance to patios, balconies, and other outdoor areas. When grown in containers, this enchanting plant can be showcased individually or combined with other complementary flowers and foliage to create captivating displays.

Container Common Diseases

In container gardening, certain diseases can affect Astrantia ‘Magnum Blush,’ primarily due to factors such as overwatering, poor air circulation, and inadequate drainage. Common container diseases that may impact the plant’s health include:

  • Root Rot: Caused by overly soggy soil or poor drainage
  • Powdery Mildew: Fungal disease favored by humid conditions and stagnant air
  • Leaf Spot: Fungal infection promoted by excess moisture on foliage

Preventative measures such as using well-draining soil, providing adequate air circulation, and monitoring moisture levels can help mitigate the risk of these diseases in container-grown Astrantia ‘Magnum Blush’ plants.

Aphids are tiny, sap-sucking insects that can infest Astrantia ‘Magnum Blush,’ particularly during periods of new growth. These pests can cause deformities in plant tissues and the transmission of viral diseases. To control aphid populations, physical removal, insecticidal soaps, or horticultural oils can be used with care to safeguard beneficial insects and pollinators.

Spider Mites

Spider mites are common pests that thrive in hot, dry conditions, often infesting plants cultivated in arid climates or indoor environments. These minuscule arachnids feed on plant sap, causing stippling and webbing on the foliage. Mitigating spider mite infestations involves employing techniques such as increased humidity, targeted spraying with water, or the use of natural predators.
