A highly adaptable grass, it will thrive in moist to wet soils and is tolerant of full sun to partial shade. A valuable addition to water gardens, rain gardens, and wildlife habitats.

Maintenance Tips

  • Trim back old foliage and spent flower stems in late winter or early spring to promote fresh growth and maintain a neat appearance.
  • Remove any dead or damaged stems as needed throughout the growing season.
  • Divide mature clumps every 2-3 years in early spring to rejuvenate growth and prevent overcrowding.
  • Allow some seedlings to naturalize for a more spontaneous look or remove them to control spread.
