Read the Latin on the tag. The upright sterile hybrid is ‘Karl Foerster’. [1] Striped leaves are ‘Avalanche’ (wide white center) or ‘Overdam’ (more green than white). Both stay more compact than Karl Foerster. [2] Korean feather reed (C. brachytricha) is warm-season, with later pink plumes. [3] Bluejoint (C. canadensis) spreads in marshes and wet prairie — not a small-garden clump. [4]

What is the difference between Karl Foerster and Overdam?

Both are the same cool-season hybrid. Karl Foerster is the green upright screen. Overdam (and Avalanche) are striped and more compact.

What is Korean feather reed grass?

Calamagrostis brachytricha — a warm-season species with later pink plumes. It is not Karl Foerster, and it can seed.

Browse by kind

Upright sterile hybrid

‘Karl Foerster’ is the sterile upright screen — narrow green foliage and early tan plumes. It does not seed around the bed.

Striped hybrid

‘Avalanche’ has a wide white stripe down the leaf. ‘Overdam’ shows more green than white. Both are more compact than Karl Foerster and share the same cool-season hybrid.

Korean feather reed

C. brachytricha is a warm-season grass with later pink plumes that loosen by early winter. It can seed. It is not the Karl Foerster clock.

Native wetland or coastal reed

C. canadensis is a spreading wetland native, not a narrow border clump. C. nutkaensis is a coastal wet native — Pacific or Nootka reed grass — for moist ground, not a dry screen.

Not feather reed grass — pampas, fountain grass, and maiden grass

  • Pampas grass (Cortaderia) is a much larger tussock with big plumes. It is not this narrow sterile hybrid.
  • Fountain grass (Pennisetum) makes arching bottlebrush spikes. It is a different genus and a different shape.
  • Maiden grass (Miscanthus) is a warm-season arching clump with a silver midrib — not Karl Foerster's tight vertical screen.

Is feather reed grass the same as pampas?

No. Pampas is Cortaderia — a large tussock. Feather reed grass here is Calamagrostis, usually the sterile Karl Foerster hybrid.

If the tag says pampas, fountain grass, or maiden grass, it is a different genus — read the Latin before you bed it as feather reed grass.

FAQ

Do we list Eldorado or Lightning Strike as extra kinds?

No. Eldorado, Lightning Strike, and similar shop selections are other striped hybrids, not extra catalog cards. The four jobs here are upright sterile, striped, Korean, and native reed.

Is Overdam a Korean grass?

No. Overdam and Avalanche are striped selections of the cool-season hybrid. Korean feather reed is Calamagrostis brachytricha.

Is Stricta the same as Karl Foerster?

Nurseries sometimes mix the two. Karl Foerster is sterile and blooms a little earlier. Confirm the name on the tag.
