Sandwort

Arenaria montana (Mountain Sandwort) forms a spectacular low evergreen cushion of small, rich, glossy, green, elliptic leaves, almost fully covered by relatively large pure white flowers in late spring or early summer. Great for rock gardens or edging paths, it will quickly fill in the spaces between flagstones, in walls or trough gardens.

Sandwort

Also called Rock Sandwort and Minuartia dawsonensis, its long, tough root enables it to establish in cracks between rocks. Often found in limestone outcroppings, Stiff Sandwort is distinctive for its linear leaves and large white flowers despite its small stature. It requires dry, hot sites and sandy soils. This plant has a limited and sporadic native range in the US and is quite rare to see growing in the wild. In Minnesota Stiff Sandwort is being considered to be elevated from 'Special Concern' to 'Threatened' due to agriculture and grazing diminishing its habitat. It is a Special Concern plant in Wisconsin.

Mountain Sandwort Seeds 6330 These easy to grow moss-like, creeping plants form dense grey-green mats of narrow leaves, topped with attractive white flowers. Blooms 2.5 cm (1″) across sit just above the foliage and flower in early to mid May. In the garden, plants spread up to 20-30 cm (10-12″) across while keeping their low growing habit of 5-10 cm (2-4″). Tolerant of moderate foot traffic, these plants are ideal for crevices in pathways and are very attractive in rockeries or trailing over walls. Perennial hardy to Zone 4. Packet contains100 seed. Blunt-leaf Sandwort seems to spread primarily vegetatively through rhizomes, often forming a dense tangle of plants. I was steward for this species for a few years at Wild River State Park and only collected about 4 seeds between the two known sites in all that time. The seed capsules rarely developed fruit and I observed the same at two locations in Ramsey County as well. A very similar species is the rare Large-leaved Sandwort (Moehringia macrophylla), which (as its name suggests) has larger leaves up to 2 inches long, sepals at least half as long as the petals, and is a more erect plant.
