Calamagrostis × acutiflora ‘Karl Foerster’
Feather Reed Grass 'Karl Foerster'
I hold the RHS | Award of Garden Merit
Calamagrostis × acutiflora ‘Karl Foerster’ is an upright feather reed grass valued for strong vertical structure without a bulky footprint. Bronze flower panicles rise above arching green leaves in early summer, fading to pale brown and remaining effective well beyond flowering. Around 1–1.5m high, it suits sunny or lightly shaded borders in most reasonably fertile, well-drained soils.
✅ Strong upright habit gives excellent vertical structure
✅ Bronze flower panicles fade attractively into winter
✅ Hardy, reliable and generally low maintenance

- Full Sun Part Shade
- Aspect Aspect refers to the direction the planting spot faces (north, south, east or west). It affects light levels, warmth and exposure.
- North South East West
- Exposure Exposure describes how sheltered or exposed a plant’s position is, particularly to wind and weather.
- Exposed / Sheltered
- Hardiness Hardiness indicates how well a plant tolerates cold conditions outdoors. Higher ratings generally mean greater frost tolerance.
-
(−20 to −15 °C) Very cold-hardy
Ideal Soil Conditions
- Soil Type Soil type describes the texture of the soil (clay, sand, loam, chalk). This affects drainage, nutrients and how roots grow.
- Soil Moisture Soil moisture tells you how wet or dry the soil should be for best growth. Match this to your garden conditions for healthier plants.
- Moist but permeable / Free draining
- Soil pH Soil pH measures how acidic or alkaline the soil is. It affects nutrient availability and can impact plant growth.
