También se conoce como Ammophila arenaria, European beach grass, European beachgrass, Marram, marram grass, sea matgrass

Marram grass is a hardy, dune-stabilizing plant that thrives in sandy, coastal environments. It is famous for its ability to trap blowing sand and build up dunes along the shore. You will mostly see this plant outdoors in natural landscapes rather than as a houseplant.

Cuidados
This grass needs full sun and sandy, well-draining soil to stay healthy. Watch for signs of rot if the soil stays wet for too long, as it prefers dry conditions. It is best left to grow in its natural, rugged environment.
- Riego
- Water only during extreme drought once established.
- Abonado
- It rarely needs fertilizer in its natural sandy habitat.
- Poda
- Trim back dead foliage in late winter or early spring.
- Trasplante
- Only repot if the plant becomes severely root bound in a container.

Seguridad
- Personas
- The plant is not toxic, but the sharp leaf edges can cause minor skin abrasions.
- Niños
- The sharp, serrated edges of the leaves can cut delicate skin, so keep it away from play areas.
- Alérgenos por contacto
- The stiff, sharp leaf blades can cause mechanical skin irritation if handled without gloves.
- Alérgenos en el aire
- The pollen may cause mild seasonal allergic reactions in sensitive individuals.
- Comestibilidad
- This grass is not considered edible for humans.

Cómo cultivarla
- Propagación
- division, seed
- Cuándo plantar
- spring, autumn
- Cuidados en invierno
- Leave the foliage standing through winter to protect the crown, then trim back in early spring before new growth appears.
- En maceta
- It is not well-suited for containers as it requires significant root space to thrive.
Division
- 1. Dig up a mature clump in early spring.
- 2. Use a sharp spade to divide the root mass into smaller sections.
- 3. Replant immediately in sandy soil.
Group this with other salt-tolerant coastal plants to create a resilient, low-maintenance dune garden.
Buenas compañeras
- Eryngium maritimum — They share similar requirements for sandy, coastal conditions.
- Armeria maritima — This low-growing perennial provides a nice contrast to the tall grass.
Especies parecidas
- Ammophila breviligulata — This is the North American counterpart that serves the same ecological role.

Lo que más preguntan
- Can I grow this in a garden without sand?
- It prefers sandy, well-draining soil and will likely struggle in heavy clay or rich garden loam.
- Does it need fertilizer?
- No, it is adapted to low-nutrient soils and excessive fertilizer can actually weaken the plant.
De dónde viene el nombre
The genus name Calamagrostis comes from the Greek words for reed and grass, while arenaria refers to its preference for sandy habitats.
Bueno saberlo
- It is also known as Marram grass.
- The deep, extensive root system can reach several meters into the sand.
- It thrives in nutrient-poor, salty environments where most plants fail.
