ARENARIA

Low evergreen plants carpet the ground creating a dense mat of mosslike foliage; small white flowers in late spring and summer. They are often used as lawn substitutes, between steppingstones, or for velvety green patches in rock gardens. Can be invasive; hard to eradicate in well-watered gardens. Providing good drainage is recommended.

Arenaria montana

Grows to 2–4 in. high; weak stems up to 1 ft. long are usually covered with soft hairs. Leaves grayish green, 1/2–3/4 in. long. Good plant to let trail over rocks or tumble over a low wall.
