It is also a component of purple moor grass and rush pastures, a Biodiversity Action Plan habitat in the United Kingdom.

[3] The natural habitat of Ajuga reptans spans across Europe, extending to the middle taiga subzone of northeastern Russia.

[5] While widely used as an ornamental shade ground cover, it is considered an invasive species in various parts of the United States[6][7][8] due to its aggressive growth and ability to form dense mats that outcompete native plants for sunlight, water, and nutrients.

Its rapid spread through both seeds and underground rhizomes can lead to significant reductions in local biodiversity, particularly in woodland and garden areas.
