About Arenaria montana L.
Arenaria montana L. is an evergreen perennial plant that reaches a height of 14 to 22 centimeters (6 to 9 inches). It bears opposite leaves that are lanceolate or ovate in shape, range in color from green to grayish-green, and measure 10 to 30 millimeters (0.4 to 1.2 inches) long. From mid to late spring, it produces dense clumps of white to near-white flowers. Each flower is roughly 25 millimeters (1 inch) in diameter, and flowers are arranged in cymes that hold 2 to 10 flowers each. This species prefers well-drained, sandy to sandy loam soils with moderate acidity, between pH 5.5 and 7.5. It also prefers moist soils, because its shallow root system makes it vulnerable to drought. Arenaria montana has been awarded the Royal Horticultural Society's Award of Garden Merit.
