Summary

Sisyrinchium arenarium, commonly known as Sand Blue-Eyed Grass, is a perennial herb that is native to Chile and Argentina, but it is not restricted to coastal sands and dunes; it also thrives in grasslands and open, rocky areas. It typically grows at a moderate rate to a height of 0.5-1.5 feet (0.15-0.45 meters) and a width of 0.5-1 feet (0.15-0.3 meters). This plant is characterized by its grass-like foliage and striking blue, star-shaped flowers with yellow centers that bloom profusely in the spring and summer, adding a splash of color to the garden.

Sand Blue-Eyed Grass is valued for its low maintenance requirements and its ability to adapt to various soil types, although it prefers sandy soils. It is often used in rock gardens, as a border plant, or in naturalized areas where its showy flowers can be appreciated. While it thrives in full sun, it can tolerate light shade and requires moderate watering, especially in well-drained soils. It is not commonly affected by serious pests or diseases, but overwatering can lead to root rot.CC BY-SA 4.0
