The plant is characterized by its cushion-forming growth habit. Its foliage is covered in dense, soft trichomes, which provide the plant with a unique silver-gray appearance and serve as an adaptation to minimize transpiration in windy, dry high-altitude conditions.
In terms of cultivation, this species requires specific environmental conditions to survive. Excellent drainage is the most critical factor; the plant will quickly succumb to root rot if grown in heavy, damp soils or exposed to excessive moisture during dormant seasons.
The ideal substrate for this plant is a mineral-rich, stony, or sandy mix with a neutral to slightly alkaline pH. It performs best in full sun or light shade, provided the surrounding air circulation remains high to prevent fungal issues associated with humidity.
While not a major agricultural crop, Draba mollissima is highly valued in horticulture. It is primarily used in specialized rock gardens and alpine houses, serving as a decorative specimen for collectors who can provide the necessary climatic simulation.
