Arenaria montana

Common Name: Mountain Sandwort

Description:
Arenaria montana, commonly known as Mountain Sandwort, is a low-growing, evergreen perennial ground cover prized for its dense, spreading habit and prolific white flowers. Blooming in late spring and early summer, this hardy plant produces masses of small, five-petaled, pure white flowers that create a carpet-like effect over its dark green, mossy foliage. It thrives in well-drained, sandy or rocky soils and prefers full sun to part shade, making it an excellent choice for rock gardens, edging, and filling gaps between stepping stones. Adaptable to Melbourne's climate, it is drought-tolerant once established and requires minimal maintenance. Mountain Sandwort is resistant to deer and rabbits, making it a reliable, long-lasting addition to any low-maintenance garden.
