Smooth Cordgrass (Sporobolus alterniflorus)

Smooth Cordgrass

Also known as: Salt-water Cordgrass

Smooth Cordgrass (Sporobolus alterniflorus) creates new land in saltmarshes by establishing a beachhead right at the edge of the sea. By doing this, the species is able to construct an extensive root system that helps keep silt from washing away. This provides a haven for other plants and animals to settle in. Over time, this dramatically increases the salt marsh area.

Pruning: Smooth Cordgrass thrives in coastal marshes and benefits from early spring pruning of old stems to promote new growth and improve air circulation. Retaining some foliage in winter aids erosion control and wildlife habitat. Cut stems to ground level pre-growth for optimal seasonal results.

Propagation: Smooth Cordgrass, a coastal perennial grass, propagates by sowing healthy seeds in a moist, well-draining medium. Consistent moisture, preferably high, is essential without waterlogging. Use a saltmarsh potting mix for saline conditions, and provide gentle warmth and sunlight to boost germination while reducing fungal risks.
