Wildlife Value:

Karl Foerster Feather Reed Grass may be used as a nesting and cover source for bird species.

Maintenance Tips:

As it does not self-seed, you may leave it up over winter for a vertical accent. In late winter or early spring, cut back the clump to 2-3 inches above the crown to give room for new growth.

Pests/Problems:

There are no major disease or insect problems. In particularly wet periods, rusts can become an issue but this typically dissipates as moisture levels drop.

Leaf Lore:

Calamagrostis x acutiflora is a hybrid between the Eurasian species Calamagrostis epigejos and Calamagrostis arundinacea. Karl Foerster Feather Reed Grass is named after the German nurseryman who discovered and introduced the variety in Europe. In 1964, Karl Foerster Feather Reed Grass was introduced to the United States and quickly became popular for its tidy habit and durability. Because of its toughness and low maintenance, Karl Foerster Feather Reed Grass can often be seen planted along parking lots, in medians, or around commercial buildings.

Companion Plants:

Karl Foerster Feather Reed Grass looks best when given adequate spacing, so be careful not to pack too many plants around it. When properly spaced, consider using Little Goldstar Black Eyed Susan or Hairy Wild Petunia to give added color.
