With its strikingly blue-green foliage, Sesleria caerulea, also known as blue moor-grass or blue Sesleria, offers a unique color palette to any garden setting. This clump-forming perennial is native to Europe and known for its low-maintenance and evergreen properties, providing year-round interest to borders, group plantings, or as an edge plant.

Key Features

The Sesleria genus is renowned for its hardiness and the blue moor-grass is no exception, with several distinctive characteristics:

blue moor-grass boasts a unique foliage color that remains consistent throughout the seasons, transitioning from blue to green.

Tips

To ensure the health and vigor of your Sesleria caerulea, water it regularly, especially in dry periods, as it is not drought-resistant.
While blue moor-grass can tolerate a range of soils, improving your soil with organic matter will result in a more robust plant.
Deadheading is not necessary for this plant, but removing old foliage in early spring can promote new growth and maintain the plant's neat appearance.
When planting Sesleria caerulea, consider spacing them about 30 cm apart to allow each clump room to flourish and create a seamless ground cover.

Ideal placement of a Sesleria caerulea

For optimal growth, Sesleria caerulea thrives in a location with full sun to partial shade. It is versatile in soil preference, accommodating a range of types, provided they are well-drained. This species, with its striking blue and green foliage, is ideal for border or group plantings where its clump-forming habit can be fully appreciated. The blue moor-grass maintains its color throughout the seasons, offering a persistent visual appeal in the garden. To ensure its health and vigor, average water provision is necessary, especially in well-draining soils that do not retain excessive moisture.

How do I plant a Sesleria caerulea?

For successful cultivation, Sesleria caerulea should be planted in well-drained soil, which can be of virtually any type, displaying the plant's adaptability. This species thrives in a location that receives full sun to partial shade, offering flexibility in garden placement. The plant, supplied in pots, can be transferred to the ground year-round, provided the ground is not frozen. Upon planting, ensure the clump-forming grass is watered sufficiently to establish a strong root system. It's important to maintain an average watering regimen to support its growth, especially during dry spells, as it is not drought-resistant.

Pruning a Sesleria caerulea

Pruning is a minimal concern for Sesleria caerulea, due to its clump-forming growth habit and modest height of 40 cm. To maintain its tidy appearance and encourage healthy new growth, simply trim back the old foliage in early spring, before the onset of new growth. This practice will enhance the plant's natural vigour and ensure the rich blue-green hues of its leaves remain vibrant throughout the seasons. It is an undemanding species that thrives with just this simple annual care.

Watering a Sesleria caerulea

Sesleria caerulea thrives best with consistent moisture, particularly when establishing itself in a new environment. This evergreen grass should be watered deeply and less frequently to encourage a strong and deep root system. During the growing season, ensure the soil remains moist but well-drained, without becoming waterlogged. In periods of drought or extreme heat, increase irrigation to maintain plant vigor. Once established, it displays some tolerance to dry spells, but regular watering will keep the foliage's distinct blue-green hue vibrant throughout the seasons.

Fertilising a Sesleria caerulea

To ensure that Sesleria caerulea thrives and maintains its vibrant blue-green foliage throughout the seasons, a considered approach to fertilization is required. This evergreen grass benefits from a light application of a balanced, slow-release fertilizer during the spring. This timing coincides with the onset of its growth period, providing essential nutrients that support the early flowering and vigorous foliage development. Care should be taken to apply the fertilizer according to the manufacturer's recommendations, gently incorporating it into the soil around the clump, and ensuring it does not come in direct contact with the leaves to prevent burn. An additional application in the early fall can help fortify the plant against the winter months, although over-fertilizing should be avoided to prevent excessive growth that could be damaged by winter weather.
