Panicum amarum (Coastal Panic Grass) is a hardy, clump-forming perennial grass that thrives in coastal environments. Its slender, arching green leaves create a graceful, flowing appearance, adding a natural, beach-like aesthetic to any garden. This drought-tolerant grass is perfect for sandy soils and areas with high winds, where many other plants struggle to grow.
In late summer, Panicum amarum produces airy, light green seed heads that turn golden in autumn, adding colour and texture to garden beds. This grass is ideal for stabilising sandy soils or creating a natural, windswept look in coastal or low-maintenance gardens. It’s also a great choice for erosion control and as a background plant for larger landscapes.
