This striking perennial grass produces slender, spiky foliage in shades of blue-green, and it's easy to grow and care for. In this guide, we'll cover everything you need to know about growing and caring for Sesleria caerulea.

What is Sesleria Caerulea?

Sesleria caerulea is a species of perennial grass native to Europe, where it can be found growing in rocky, mountainous areas. It belongs to the family Poaceae, which includes many other common ornamental grasses like Miscanthus, Panicum, and Pennisetum. Sesleria caerulea is known for its slender, spiky blades of foliage, which typically grow to a height of 10-12 inches. The foliage is a distinctive blue-green color and has a slightly wavy texture.

How to Grow Sesleria Caerulea

Sesleria caerulea is an easy-to-grow ornamental grass that thrives in full sun to partial shade. It prefers well-draining soil and will not tolerate wet feet, so make sure to plant it in a location with good drainage. This grass is drought-tolerant once established, but it will appreciate occasional watering during hot, dry spells. Sesleria caerulea is hardy in USDA zones 4-9, so it can be grown in most parts of the United States.

To plant Sesleria caerulea, dig a hole that is slightly larger than the root ball of the plant. Make sure the top of the root ball is level with the surface of the soil, then backfill with soil and tamp down gently. Water thoroughly after planting, then monitor the soil moisture level for the first few weeks until the plant becomes established.

Caring for Sesleria Caerulea

One of the best things about Sesleria caerulea is that it requires very little maintenance once it's established. Here are a few tips for keeping your blue moorgrass healthy and looking its best:

• Water regularly during the first growing season to help the plant become established.
• After the first year, Sesleria caerulea is drought-tolerant and does not require regular watering.
• Trim back any dead or damaged foliage in the spring before new growth appears.
• Divide the plant every 3-4 years to prevent overcrowding and promote healthy growth.
• Fertilize once a year in the spring with a balanced fertilizer like 10-10-10.
• Watch out for pests like slugs and snails, which may be attracted to the tender foliage of Sesleria caerulea.
