Spartina alterniflora, commonly known as Smooth Cordgrass, is a native, perennial grass found along the Atlantic and Gulf coasts of North America. This salt-tolerant species plays a critical role in coastal wetland ecosystems, forming dense stands that stabilize shorelines and protect against erosion. Growing 3 to 6 feet tall, Smooth Cordgrass features tall, sturdy stems and narrow, bright green leaves that turn golden in the fall.

It thrives in tidal marshes and estuaries, where its extensive root systems anchor the soil and reduce the impact of waves and storm surges. Spartina alterniflora also provides vital habitat for fish, birds, and invertebrates, supporting a rich diversity of coastal wildlife.

Why Choose Spartina alterniflora?

• Thrives in tidal marshes and saltwater environments, ideal for coastal stabilization
• Provides critical erosion control and protects against storm surges and rising tides
• Offers essential habitat and food sources for fish, birds, and pollinators

Cultivating Tips

• Plant in full sun in wet, salty soils along shorelines, tidal marshes, or estuaries
• Requires regular water exposure and tolerates flooding and brackish conditions
• Low-maintenance once established, with minimal care needed

Design Ideas for Your Garden

• Use in coastal restoration projects to stabilize wetlands and prevent erosion
• Ideal for bioswales, rain gardens, and shoreline buffer zones in ecological landscapes
• Combine with other salt-tolerant native plants like Juncus or Spartina patens for habitat restoration

Ecological Benefits

• Provides habitat and shelter for coastal birds, fish, and beneficial insects
• Stabilizes soil and reduces coastal erosion through its extensive root system
• Improves water quality by filtering runoff and trapping sediments in estuarine environments
