The Story

Plant Bio

A tall, robust, warm-season native grass with long, arching leaves that have sharp, serrated edges. It forms dense colonies via tough, rope-like rhizomes and is excellent for erosion control. The leaves have a prominent white midrib and turn a beautiful golden-yellow in fall. Its name 'cord grass' refers to its strong, cord-like rhizomes, which make it an aggressive spreader in moist soils.

Planting

How to Grow

  1. Select a site in full sun; it tolerates a wide range of soils.
  2. It thrives in moist to wet conditions but tolerates some drought.
  3. Dig a hole large enough to accommodate the root ball.
  4. Place the plant in the hole, with the crown at soil level.
  5. Backfill with soil and water deeply.
  6. Be aware of its spreading habit when choosing a location.

Pro Tip

Use this grass with caution in small gardens; its rhizomes are very aggressive. Consider installing a root barrier if spread is a concern.

Keep It Thriving

Care Guide

Do

  • Plant in full sun for the strongest growth.
  • Use it in areas where its spreading nature can be an asset, like large banks.
  • Provide supplemental water in very dry conditions to keep it looking its best.
  • Cut back foliage in late winter to allow new growth to emerge.

Don't

  • Do not plant it in a small, mixed perennial border without containment.
  • Avoid handling the leaves without gloves, as the edges are very sharp.
  • Don't plant in deep shade.
  • Do not fertilize; it does not require it.
