Arenaria montana, otherwise known as the Mountain Daisy, is a wonderful evergreen, hardy and durable perennial. Beautiful white flowers in early summer cover dense green foliage, which is ideal for adding texture and depth to garden border pieces. Arenaria is best planted in a well-drained sandy and fertile soil. They are best placed in an area with full sun or partial shade. Sandstones are suitable for decorating low-maintenance structures, villas and gardens.
