## Appearance

The European marram grass has stiff, rolled, grey-green leaves that grow in dense, upright clumps, often reaching over a meter tall. Its leaves curl inwards, giving them a needle-like appearance, a distinct feature from broader-leaved grasses.

## Taxonomy

- **Kingdom:** Plantae
- **Phylum:** Tracheophyta
- **Class:** Liliopsida
- **Order:** Poales
- **Family:** Poaceae
- **Genus:** Calamagrostis

## Interesting facts

- Early Europeans used its tough leaves to weave ropes, mats, and even thatch roofs!
- Its roots can grow up to 10 feet deep, helping it find water in dry sand!
- Marram grass can survive being completely covered by sand and still grow back!
- This amazing plant actually helps build sand dunes higher by trapping blowing sand.

## Special abilities

- **Sand Anchor:** European marram grass can grow incredibly deep, extensive roots that hold shifting sands in place, helping it survive strong winds and erosion.
- **Water Saver:** European marram grass has leaves that roll inwards to create tiny tubes, trapping humid air and dramatically reducing water loss in dry, sandy environments.
- **Burial Buddy:** European marram grass can grow taller when buried by sand, which helps it thrive and create new dunes instead of being suffocated.

- **Spread:** 30-90 cm
- **Flower Size:** 0.5-1.5 cm
- **Bloom Season:** Summer
