  • Position: full sun or partial shade
  • Soil: dry or wet, well-drained soil
  • Rate of growth: fast growing
  • Flowering period: early summer to autumn
  • Hardiness: fully hardy

    A stiff, erect habit is the defining feature of this grass, named after the famous German plantsman who introduced it to the public in the 1950s. Plant it en masse to form a feathery screen, or in small groups to add height and definition to a perennial border. It also looks good planted next to buildings. This is one of the earliest perennial grasses to get going, with shoots appearing in early spring, followed by flowers that are green first, then fade to buff.

  • Garden care: Very low maintenance, it simply needs to be cut down to the ground in February. Don’t be tempted to chop it earlier, as its wheat-coloured stems add drama and strong winter presence to the garden.

Easy to establish and flowered in their first year. Was coveting this plant for a while and was not disappointed. Mesmerising to watch the flowers sway in the breeze.

Great for winter structure and movement

A big upright grass,good at the back of a mixed herbaceous planting. It can look a bit untidy so best planted with some shelter from wind.Don't be tempted to be too tidy in the autumn as this grass comes into its own in autumn/early winter giving movement and structure when everything else is dying back

I bought this for my late father's garden and happily it grew very quickly. It offers movement and height in that area of the garden and I hope the new people decide to keep it there. Given half a chance to bulk-up and spread out it will look even better.

Have had this grass in pots for a few years with no problems, provides great movement as it billows in the breeze. Mixed with Crocosmia it looks fantastic at this time of year.

Hi, the 9cm pot is smaller than we were hoping to buy this in. Can you give me an idea of how quickly this would get to a metre in height please? Many thanks.

Matt

Hello, These are pretty fast growers, but ultimately the growth rate is determined by external factors such as the availability of water, light and nutrients. If you want a more immediate impact, we do have a larger sized (2-litre) plant, which will be a year or so older than the 9cm one - please click on the following link to go to both. http://www.crocus.co.uk/search/_/search.Calamagrostis-%C3%97-acutiflora-Karl-Foerster/sort.0/

Helen

Hello. I would like to plant this to screen a wall . The area is sheltered and gets the east sun all morning and then south sun until about 2pm. I live in Edinburgh... Thank you

Sea Glass

Hello, It will be happiest in a sunnier spot, however provided it gets a reasonable amount of sun, it should be fine.

Helen

How many pots (small or big ones) would I need to build a screen along a 2m wall?

Ruby

Hello, It really depends on how impatient you are and what type of effect you are trying to create. These plants will eventually form a clump around 60cm across, however if you want a hedge-like effect, then I would recommend planting them at 30cm intervals as they will fill in faster.

Helen

Hi Do you think these grasses would be suitable to screen an oil tank in a quite a windy area? Thanks

JoBo

Hello, This can be a bit tricky, as while the more established plants tend to hold up better in a windier spot than the younger ones, I would not recommend growing them in a very exposed position.

Helen

Hi there, I am looking on your site for a nice upright, oaty-turning grass to add height to a naturalistic planting bed, with the other grass being Stipa tenuissima. But the bed and garden is small, so the tall grass needs to retain a relatively narrow footprint and not to arch too much at the top. Do you have any suggestions? I love Karl foerster, but have been told it's base grows too wide. Thanks very much.

Hello, I would not rule out Calamagrostis × acutiflora 'Karl Foerster' as it does have a distinctly upright habit, and it it does get too big, it can be lifted and divided in mid-spring. As for alternatives, there are a couple of things that spring to mind - here are some of my favourites... Helictotrichon sempervirens http://www.crocus.co.uk/plants/_/helictotrichon-sempervirens/classid.2905/ Miscanthus sinensis 'Kleine Silberspinne' http://www.crocus.co.uk/plants/_/miscanthus-sinensis-kleine-silberspinne/classid.2023/ Panicum virgatum 'Heavy Metal' http://www.crocus.co.uk/plants/_/panicum-virgatum-heavy-metal/classid.2000004386/ Panicum virgatum 'Shenandoah' http://www.crocus.co.uk/plants/_/panicum-virgatum-shenandoah/classid.2000007020/

Helen

Is this grass suitable for growing in a container? What maintenance would be required in terms of fertilising, repotting etc?

Dahliadarling

Hello, This plant looks so great when planted in big blocks in the border, but it is possible to grow it in a pot filled with John Innes No.2 too. You will need a biggish pot - I would suggest something with a diameter of at least 45cm and a sturdy base, so it does not topple over. As for maintenance, it is pretty easy to care for, just make sure it is well watered in the growing season and cut it back hard when it starts to look really tatty. You can also give it the occasional feed with a good, general-purpose fertiliser such as MiracleGro from spring to midsummer.

helen

Please can you tell me how far part these should be planted?

Naughty Nicky

Hello there These plants can grow to at least 60cm wide eventually. The planting distances between the plants depends really on the look you would like to create, and how patient you are waiting for them to grow But normally I would plant them 50-60cm apart.

Indulge a passion for ornamental grasses by creating a prairie- or meadow-style garden. They can be richly planted with native wildflowers or a selection of complementary perennials and self-seeding annuals to create a naturalistic planting effect.

Shimmering late-season grasses

With the garden devoid of summer froth and carpeted in autumn leaves, certain plants shine at this time of year, a well-placed grass shimmering against a winter sunset, or the reddish brown, silky feathers shimmering in low sunlight are winter treats.

Late ornamental grasses

Late-season grasses come into their own from September adding another element or two - movement and texture to your garden. Most are tall and graceful and most move and sway with a gossamer presence. As autumn continues the texture of the awns, be it soft
