Blue Moor Grass

Don't worry. Sesleria albicans is neither poisonous nor toxic. It is completely safe to grow in family gardens where small children, dogs, cats, and other pets are present.

Blue moor grass (Sesleria caerulea) is a fully hardy, long-lived perennial that can withstand frosts down to -28 °C (zone 5a) in our conditions without any damage. It does not require any special winter protection such as conifer branches or garden fleece. On the contrary, its evergreen leaves add a beautiful winter effect to the garden.

This ornamental grass brings the garden to life very early in the spring. It blooms as early as April and May, when other plants are often still dormant. It produces interesting brown spikelets that gradually fade into delicate beige shades throughout the spring.

No, you don't need to worry about that. Sesleria caerulea forms dense, yet very neat and compact clumps. It does not spread via invasive underground rhizomes, nor does it self-seed. It will remain exactly and tidily where you first plant it.

Unlike many other grasses (e.g., Miscanthus), blue moor grass should not be cut back completely to the ground in spring. Since its leaves can remain evergreen under good conditions, you only need to gently 'comb' the clump with your hands in early spring or carefully prune out only the dry and damaged leaves with garden shears so that the plant looks fresh and tidy again.

We recommend planting the seedlings with a spacing of 40 cm. If you plan to create a larger area, 6 to 9 seedlings are ideal for one square meter. In this way, they will create a beautiful, continuous, yet not overcrowded patch of neat clumps.

This plant primarily requires good drainage, but it is very undemanding in terms of nutrients. It does not need regular fertilization at all. In over-fertilized soil with an excess of nitrogen, its leaves could lose their beautiful grey-green color, and the plant would not maintain its typical compact and neat shape.

Water a newly planted seedling regularly until it is fully established and starts growing. Once established, the plant is very drought-tolerant and gets by easily on natural rainfall. However, if the summer is extremely dry and hot, occasional watering will benefit it and help keep the leaves beautifully green.

Yes, the spring flowers of blue moor grass are very suitable for cutting and drying. The delicate beige spikelets hold their shape perfectly when dried and look great in small dried arrangements, wreaths, or simply as a minimalist natural decoration in a vase.

Yes, it is best propagated by dividing the clumps. This is a long-lived perennial that will form strong, mature clumps after just a few years. Simply dig them up carefully in early spring or autumn, divide them into smaller parts using a spade or knife, and plant them immediately in new locations. Do not forget to water thoroughly after division.

Blue moor grass (Sesleria) thrives best in a sunny location or partial shade. It likes well-drained, somewhat sandy soil, similar to that found in its natural rocky habitats. In heavy, constantly waterlogged soil, its roots could start to rot.

Yes, absolutely. Blue moor grass is also excellent for growing in containers. It forms nice, compact clumps that grow to a height of about 20–30 cm, which look great in pots all year round. Just make sure the pot has good drainage at the bottom and that the substrate is sufficiently permeable (e.g., lightened with sand or perlite).

Not at all! It is an extremely undemanding perennial that is not prone to common pests or diseases. It is a very problem-free and hardy plant, so even a complete beginner can handle growing it with ease.

Although Sesleria albicans is very hardy and not prone to diseases, if it begins to wither like this, the most common problem is waterlogged and heavy soil, especially in the winter months. Check to see if the plant is sitting in water. If so, transplant it to a drier spot or improve its bed with gravel and sand for better drainage.
