Karl Foerster Feather Reed Grass is a hardy, easily grown grass that is one of the most popular of all the ornamental grasses. It forms a dense clump of green leaves, topped with tall, upright stems of nodding seed-heads, that are soft-purple to begin with, and then turn sandy-brown, lasting for months, even into snow. This plant is incredibly hardy, thriving from zone 3 to zone 9. It begins to flower early, so even in areas with a short growing season you can be sure you will have plenty of beautiful stems to look great in the garden, or to cut for flower arrangements. Plant this grass as a specimen, in groups, or as an informal hedge, swaying in the breezes.

  • Beautiful strong vertical accent
  • Long-lasting sprays of seed-heads
  • Hardy to zone 3, and early flowering
  • Thrives even in wet soils
  • Clump-forming and not invasive

Grow Karl Foerster Feather Reed Grass in sun or partial shade. It thrives in all soils, including clay, and grows tallest in damp soil, even growing in those difficult wet spots, or along a stream. It is a clump-forming, non-invasive grass, that will not spread and take over parts of your garden. Although it has many beautiful seed heads, the seeds are sterile, so it will not germinate and cannot become a weed in your garden, or in surrounding areas. This plant is not eaten by deer or rabbits, and it has no significant diseases or pests. For a dramatic accent in your garden, with an easy to grow, cold-hardy, tough, and trouble-free plant, this is a top pick of the ornamental grasses.
