Micranthes stellaris, commonly known as Starry Saxifrage or Star Saxifrage, is an evergreen perennial herb that thrives in the cold climates of the Northern Hemisphere, including Arctic regions and alpine zones of mountains. It is typically found in moist but well-drained, rocky slopes and crevices, often near melting snow, where it contributes to the fragile tundra and alpine ecosystems. Starry Saxifrage reaches a modest height of 0.3-1 feet (0.09-0.3 meters) and forms a low, cushion-like mound of foliage.

The plant is notable for its star-shaped, white flowers with contrasting yellow or red centers that bloom in the summer, providing a showy display against the green, sometimes reddish-tinged leaves. The flowers attract pollinators and are valued for their delicate beauty in rock gardens and alpine collections. Starry Saxifrage is appreciated for its hardiness and ability to thrive in challenging environments, making it a suitable choice for gardeners looking to create naturalistic settings. It requires well-drained soils, such as clay, loam, or sandy types, and consistent moisture, though it can tolerate drier conditions once established. It performs best in full sun to part shade, reflecting its natural preference for open yet somewhat protected habitats. While generally disease-free, it can suffer from root rot if overwatered or planted in poorly draining soils.CC BY-SA 4.0
