Arenaria montana (Mountain Sandwort)

Arenaria montana, commonly known as Mountain Sandwort, is a low-growing, mat-forming perennial featuring delicate, white, star-shaped flowers that bloom profusely above small, dark green, needle-like foliage. This hardy ground cover creates a dense, cushion-like mound, making it ideal for rock gardens, borders, or as a ground cover in sunny areas. Its compact habit and charming flowers make it a favorite for adding softness and elegance to garden spaces.

Arenaria montana grows best in well-drained, sandy, or rocky soils and thrives in poor soil conditions, making it ideal for low-maintenance and xeriscaped gardens. This drought-tolerant plant requires minimal care; occasional trimming after flowering can encourage a neat appearance and prevent legginess. It pairs beautifully with other low-growing perennials such as sedums, creeping phlox, or dianthus, creating a vibrant and textured landscape. The flowers attract pollinators like bees, while the plant's dense foliage resists deer and rabbits. With its ability to thrive in difficult soils and its delicate yet durable nature, Mountain Sandwort is a versatile choice for rock gardens, edging, or as an evergreen ground cover in sunny garden spaces.
