What is this dream-grass plant and why such a name?

Dream-grass is a type of ornamental grass grown for its soft, feathery foliage and its ability to remain evergreen in mild climates. It is also known as Festuca ovina glauca, blue fescue, or sheep's fescue. The name "dream-grass" comes from the way the foliage looks when it is in full bloom, with its soft, wispy blades resembling the dreamy appearance of clouds in the sky. The plant is often used in ornamental gardens and landscaping, as it is relatively easy to maintain and can tolerate a wide range of conditions. It is also a popular choice for naturalizing areas, as its evergreen foliage provides year-round color and texture. Dream-grass is a low-maintenance plant that is drought-tolerant and requires little to no fertilization or pruning.
