Dahurian mouse-ear
Cerastium davuricum
Description
Dahurian mouse-ear (Cerastium davuricum) is a perennial herbaceous plant belonging to the Caryophyllaceae family. While not a conventional agricultural crop, it is a significant species in horticultural and ecological restoration contexts due to its hardy nature.
The plant originates from the regions of East Siberia and the Russian Far East. It is naturally adapted to harsh environments including stony slopes and steppes, where it has developed resilience to extreme temperature fluctuations and limited nutrient availability in the soil.
Botanically, it is characterized by its glandular-pubescent stems and lanceolate leaves. The white flowers exhibit the distinct split petals typical of the genus Cerastium, creating a delicate appearance that is highly valued in its natural habitat and during the blooming period.
Regarding cultivation, the plant requires excellent soil drainage and full sun exposure. It is highly susceptible to root rot if grown in heavy or waterlogged substrates. Minimal fertilization is recommended, as this species is adapted to nutrient-poor soils and may become leggy if overfed with nitrogen.
In terms of agricultural and horticultural use, it is primarily employed in rock gardens and alpine planting designs. It serves as a decorative perennial that provides ground cover, helping to stabilize soil on minor slopes and preventing erosion in decorative landscapes.
