Alpine Sandwort
cherleria obtusiloba
Alpine Sandwort (Cherleria obtusiloba) is a resilient, low-growing perennial plant that thrives in some of the harshest environments on Earth. Sprouting in dense, moss-like cushions, this remarkable alpine specialist hugs the ground to escape the punishing winds and freezing temperatures of high-altitude mountain peaks. During its short summer blooming window, these green mats transform into a beautiful spectacle, blanketed in tiny, star-shaped white flowers. Its compact, dome-shaped cushions act as natural heat-trappers, allowing the plant to photosynthesize efficiently even when surrounded by snow patches. Highly valued as a 'nurse plant,' Alpine Sandwort creates a microhabitat that accumulates organic matter and traps moisture, paving the way for other less hardy alpine species to colonize barren rocky terrain.
生息地: Typically found in dry, exposed alpine tundra, gravelly ridges, fellfields, and rocky slopes at or above the treeline.
外見
This species is easily recognized by its dense, mat-forming cushion growth habit, which closely resembles a clump of moss. It features tiny, tightly packed, needle-like green leaves that are slightly hairy and sharp-tipped, measuring only about 5 to 10 millimeters long. During the mid-summer flowering season, the foliage is adorned with small, five-petaled flowers that range from creamy white to pale yellow. Each flower, approximately 6 to 10 millimeters in diameter, sits on a short, hairy stalk just above the foliage, displaying prominent orange or yellow anthers at its center.

おもしろい事実
Alpine Sandwort cushions can survive for over a century, growing only a few millimeters in diameter each year in their harsh mountain homes.
Despite looking like soft moss, its needle-like leaves form extremely tough, rigid cushions that can withstand freezing winds and light trampling.
The dense interior of the cushion traps dead leaves and debris, creating a self-fertilizing compost pile that nourishes the plant's own roots.
特殊能力
能力
Cushion Growth Habit
The dense, low-to-the-ground dome shape reduces wind exposure, limits water loss, and traps warm air within the foliage.
能力
Deep Anchor Taproot
A sturdy, elongated woody taproot anchors the plant securely in loose talus and reaches deep water sources amidst dry rocky soil.
能力
Thermal Regulation
The plant acts like a solar collector, maintaining internal temperatures up to 15 degrees Celsius warmer than the ambient alpine air.
