Few-flowered mouse-ear

Few-flowered mouse-ear (lat. Cerastium pauciflorum) is a herbaceous perennial plant belonging to the Caryophyllaceae family. This species is known for its ability to form dense, low-growing mats of foliage, making it a popular choice for rock gardens, ground cover applications, and decorative landscaping. It is characterized by its resilience and adaptation to cooler temperate climates.

The native range of Cerastium pauciflorum encompasses large areas of Eastern Asia, including the Russian Far East, Eastern Siberia, Japan, and Northeastern China. In these regions, the plant naturally inhabits moist meadows, riverbanks, and woodland edges. Its evolutionary adaptation to these habitats makes it suitable for gardens that experience moist, temperate conditions and requires careful site selection in drier climates.

Botanically, the plant features branched, slightly pubescent stems and opposite, lanceolate leaves. Its most distinctive feature is the white, five-petaled flowers which are deeply cleft at the tips, typical of the genus Cerastium. During the blooming season, the plant produces a visually striking display of white blossoms that attract various pollinators, contributing to local biodiversity.

Agricultural and horticultural requirements focus on providing well-drained, fertile soil with consistent moisture. While the plant is robust, it thrives best in positions that offer full sun or light shade. It is not overly demanding in terms of fertilization, though an application of balanced compost or a slow-release fertilizer in early spring can encourage more vigorous growth and a longer flowering period.

Common issues for this species include sensitivity to waterlogged soils, which may induce root rot, and occasionally powdery mildew during periods of high humidity and poor air circulation. Proper spacing between plants and ensuring good drainage are the primary preventative measures. In landscaping, it is highly valued for its low-maintenance nature and its ability to act as a living mulch, suppressing weed growth effectively.
