Arenaria balearica, the mossy sandwort, is a species of flowering plant in the family Caryophyllaceae, which also includes carnations.. As suggested by its common name, it is indeed native to the island of Corsica, which is located in the Mediterranean Sea and is a territorial collectivity of France. The plant also naturally occurs on this neighboring Italian island. It can be found in certain parts of the Italian peninsula, particularly in rocky, limestone-rich areas.
This plant grows approximately 2-6 inches tall. It can spread quite a bit more laterally, forming mats or clumps that can cover an area of 12 inches or more in diameter. The leaves are tiny, often not more than a few millimeters long, contributing to its overall low-growing, compact form. The flowers are small, white, and star-shaped, sitting close to the foliage or slightly above on short stems. Flowers bloom in late spring to early summer.
Corsican Sandwort prefers rocky or stony places, often in limestone areas. It can be found in crevices, on walls, or in other well-drained, often nutrient-poor soils. It’s well-adapted to dry conditions. Not typically listed as endangered, but like many wild plants, it can be threatened by habitat destruction in its natural environment.
Ecological and Landscape uses
- Its flowers are a source of nectar for small insects.
- Works well with other Mediterranean or alpine plants like thyme, sedum, or small species of dianthus.
- Provides ground cover which can help in soil erosion control in rocky or sloped areas.
- Perfect for creating an alpine garden feel, where it can mimic the high-altitude, rugged environments with other low-growing alpine plants.
- it’s excellent as a ground cover, especially in areas where you want to suppress weeds or cover bare soil without needing a plant that will grow too tall.
- Can be grown in pots or troughs, especially those designed to mimic alpine conditions. Its trailing habit can also provide a nice spill-over effect in taller containers or hanging baskets.
- In more natural or wild garden settings, it can be allowed to spread freely to give a natural, unmanaged look, particularly useful in replicating Mediterranean or mountainous sceneries.
Cultivation
- Growth: It’s often used in rock gardens, alpine gardens, or as ground cover due to its ability to spread and cover ground with its green foliage and delicate flowers.
- Sunlight: Prefers full sun but can tolerate light shade.
- Soil: Well-drained soil is crucial. Sandy or gritty soils with low fertility are ideal.
- Watering: Low water requirements; it’s drought-tolerant once established.
Propagation
- Seeds: Can be sown directly in the garden or started indoors. Germination might require cold stratification to mimic natural conditions.
- Cuttings: Taken in spring or early summer can root in gritty compost.
- Division: Mature clumps can be divided in spring or autumn for propagation.
