The plant exhibits specific biological traits, such as a basal rosette of lanceolate leaves and an erect stem covered in stellate hairs, which gives it its common name. The stem typically reaches a height of 10 to 30 centimeters depending on local environmental conditions.
The distribution range of the species covers mainly the northern and temperate latitudes of Eurasia, as well as mountainous regions. It thrives in well-drained, dry, or rocky soils and is commonly found in limestone habitats and alpine meadows.
The species demonstrates high resilience to cold temperatures, enabling its survival in harsh climatic conditions. It requires ample sunlight for optimal growth and is sensitive to heavy shading or excessive soil moisture levels.
The economic utility of Draba incana is limited. While it was occasionally used in traditional herbal medicine, it is currently of primary interest to field botanists, ecological restoration projects, and landscape architects specializing in rock garden design.
