Best ornamental grass - Pampas grass

Updated on

Have you thought about ornamental grass for your space? Whether you're looking for a statement plant to add some airy elegance to your garden or a spiky, structural number to add a little drama to your borders, ornamental grasses tick all the boxes. There is also an untapped air of whimsicality to this outdoor plant, which we are happy to explore. If you want to keep your garden bang up-to-date on style and design, they're worth introducing to your outdoor space.

If you're keen on these outdoor ornamental grass plants, we recommend planting them in autumn or making them an addition to your springtime garden. Ornamental grasses are grown primarily for their aesthetic appeal in gardens, landscapes, and ornamental plantings. These grasses are prized for their graceful, flowing foliage, and in many cases, their striking seed heads that add texture, movement, and visual interest to outdoor spaces. They are a great plant for birds, providing habitat and food. They feed on the seeds of grasses and nest in the dense growth below.

To tidy up your grass after winter, comb through it with a gloved hand or fork in early spring to remove dead leaves. If you need to keep the soil well-drained but moist in summer, dig in compost or use a soil improver or conditioner. Remember: feed ornamental grass with a controlled-release fertiliser to encourage growth and add a generous layer of compost or mulch around the plant in autumn. We recommend adding a water-retention gel or a rich compost.

Best ornamental grass for your garden

Wispy, pale and compact

Description

'Stipa tenuissima' or Mexican Feather Grass always features heavily in gardens at summer flower shows, after which sales go through the roof! A neat, compact grass with stiff, thin stems, a strong arching shape, and an open structure, it's almost transparent, rather than the dense effect of some other grasses. Also known as ponytails or angel hair, its wispy, pale leaves are topped with fluffy heads of silvery-green flowers from June to September.

Customer Review: "My grasses arrived well packaged and in good condition. I've bought from T&M before and would do so again."

Pros

  • Fine, billowing, thread-like foliage
  • Fluffy, buff-coloured flowerheads
  • Tactile, deciduous grass

Cons

  • Flowers only in May

Pink and silver flowers

Description

'Hordeum jubatum' or Foxtail Barley is short-lived but it will self-seed to grow new plants. Give it a warm, sunny position and it'll reward you with delicate, pale pink, silvery flowers. Plant in drifts and the flowers will sway in the breeze creating attractive waves. Looks great in a gravel garden or at the front of a modern border.

Customer Review: "I'm so pleased with the germination rate of these seeds. I'm looking forward to seeing the squirrel tails to grow."

Pros

  • A large swathe of pink flowers
  • Easy to grow from seeds and will self-seed
  • No reported toxicity to pets

Cons

  • Short-lived but will self-seed

Grey-blue fades to brown

Description

Grown for its stiff, architectural blue foliage, the Festuca Glauca (or Blue Fescue) is a useful evergreen grass for year-round interest. These low-growing hummocks of grey-blue, needle-thin leaves are evergreen, with pretty flower spikes in summer slowly fading to brown. Other than a comb-through in spring to remove any dead foliage, it needs zero attention from you. It has a particularly neat, clump-forming habit that remains nicely compact as it grows.

Customer Review: "Good, healthy plants that arrived in perfect condition. A little small at the moment but they look good at the front of the border and seemed to have settled in well."

Pros

  • Stiff, architectural blue foliage
  • Useful evergreen grass for year-round interest
  • Short, blue-green flower spikes

Silky, cream-white flowers

Description

With huge, graceful feathery heads of silky cream-white flowers, this majestic ornamental Pampas Grass has boomed in popularity over the past year both indoors and outdoors. Fully hardy, these make a striking feature for late summer and autumn and still look attractive in the winter frost. These come supplied in approx. 2-litre containers.

Customer Review: "Very pleased with this plant. Looks strong and healthy."

Pros

  • Looks great blended with shrubs and grasses
  • Resistant to drought and freezing temperatures
  • Superb grass for late summer and autumn effect

Cons

  • May be too big for some spaces

A contemporary look

Description

The upright blades of Japanese Blood Grass (or 'Imperata cylindrica Rubra') are green at the base and red at the tip, glowing like flickering flames when backlit by the sun. It's not terribly tough, so plant it in a sunny spot and keep it cosy with a layer of mulch in autumn. Or, grow it in a pot and pop it under cover in winter.

Pros

  • Resilient, easy-to-grow plants
  • Stunning, spiky grass
  • Add contrast to your flower beds

Cons

  • No customer reviews

Adds a sculptural edge

Description

This Chasmanthium Latifolium originates from North America where it's also known as northern sea oats. It boasts masses of unusual flat flowers that add a sculptural edge to a modern plot, and the whole plant dries to a rich russet-brown colour in autumn. Give it a sunny spot and cut stems to ground level in early spring.

Customer Review: "Beautiful and very nice to see enjoyed growing from seed."

Pros

  • Lovely cascading over a path
  • Could fare well arranged in a vase
  • Delicate upper-storey perennial grass

Cons

  • Some customers didn't have any luck

Resembles a squirrel tail

Description

'Pennisetum alopecuroides' or Chinese Fountain Grass has long, arching, slender, green leaves and fluffy, brush-like, brown spikelets in summer that resemble a squirrel's tail. Decorative and low-maintenance, it can grow up to 150cm and thrives in the sun with fertile, well-drained garden soil. Growing in clumps, it's ideal for filling gaps in your borders.

Customer Review: "Looks lovely. Planted in my wildflower meadow (just sown)."

Pros

  • Highly decorative ornamental grass
  • Almost all year-round interest in the garden
  • A low-maintenance plant

Cons

  • Few customers reported poor condition

Keep this cosy through winter

Description

We can't get enough of this fluffy Pennisetum villosum with flowers of whitish-green that take on purple tints as they mature. This grass won't survive a chilly winter so keep it cosy with mulch or grow in a pot and bring it undercover in late autumn. Plant the wheat-like feathertop grass in a sunny, well-drained location. Their fluffy texture will soften surrounding planting schemes and they look particularly good when the sun catches them from behind.

Customer Review: "Lovely planted under pleached fruit trees adding winter interest."

Pros

  • Greeny-white, wheat-like flowers
  • This grass usually self-seeds
  • Loosely tufted bunch in spring

Cons

  • Requires extra maintenance through winter

Whimsical, cottage feel

Description

'Eriophorum scheuchzeri' gets its common name (White Cotton Grass) because of the fluffy, white flowerheads that look like cotton wool balls floating among clumps of grassy foliage. Native to Alaska, Canada, Greenland, and Iceland, it's super hardy and can grow up to 30cm. It needs to be kept moist so would do well next to a garden pond, and you can expect to see the white flowerheads from June to September each year.

Pros

  • Slender, grass-like leaves
  • Forms a spreading clump
  • Fluffy-looking spikelets

Cons

  • No customer reviews

Perfect for gravel gardens

Description

Planted in large drifts at the edge of a path or beneath trees, this slow-growing Hakonechloa macra 'Aureola' grass will bring movement to your garden with its tumbling cascades of striped yellow and green leaves. Plant in full sun, where the leaves can develop a reddish tint or part shade, and cut back to the base in spring.

Customer Review: "Really good size plants! I have planted them and can't wait for them to show their full potential."

Pros

  • Clump forming grass
  • Perfect for sun or shade
  • Ideal for containers or in gravel gardens

Cons

  • Some customers have had some issues with quality

Oat-like flowerheads

Description

Slender leaves sit atop towering stems, creating quite an impression. Plant the Stipa gigantea (golden oats) where it will catch the sun and its seedheads will shimmer like gold into winter. The leaves have sharp edges so wear gloves when handling and comb through in spring to remove dead foliage. Supplied in 3 x 9cm pots.

Customer Review: "This is a very impactful, very tall grass with amazing, tall, golden spears that shimmer in the sun. It has proved difficult, though, to keep them in shape. Some of the spears go off at an angle and look less attractive. If planted with other things of contrasting colour it can look fantastic. A real statement plant that we first got to know from seeing it in a National Trust garden."

Pros

  • Glistening, golden, oat-like flowerheads
  • Majestic semi-evergreen grass
  • Perfect for a mixed, sunny border

Cons

  • One or two customers feel that the results were poor

As its name describes, miniature rabbits' tails are ideal to use as an upper-storey in any cut flower bunch and container. It should be well-drained and in full sun.

FAQs

What types are there?

There are numerous species and varieties of ornamental grasses, coming in various growth habits, including clumping, spreading, and trailing forms. Some are evergreen, while others are deciduous, meaning they lose their foliage in the winter. If you were keen on learning more, we've listed some common types of ornamental grass:

Fountain Grass (Pennisetum): Known for its arching, fountain-like growth habit, fountain grasses are popular for their fluffy, bottlebrush-like flower spikes.

Japanese Silver Grass (Miscanthus): These grasses are known for their tall, upright growth and feathery plumes that can be quite showy.

Switchgrass (Panicum): Switchgrass is a native North American grass that offers a range of cultivars with different heights and foliage colours.

Feather Reed Grass (Calamagrostis): This grass features upright, narrow foliage and feathery plumes, making it a popular choice for formal gardens.

Blue Fescue (Festuca glauca): A smaller ornamental grass with striking blue-grey foliage.

Maiden Grass (Miscanthus sinensis): Tall and graceful, these grasses are prized for their silky plumes and colourful fall foliage.

Ornamental grass planting ideas

Match with hardy geraniums and Siberian bugloss for the ultimate low-maintenance showstopper patio pot.

Plant into a trio of small patio pots to pretty up and punctuate your paving or decking.

Plant in a row to use as a garden screen from neighbours, to divide up your garden, or to frame a seating area.

Because of its cascading shape, ornamental grasses such as the Mexican feather grass look gorgeous in a wide shallow bowl.

Use as the perfect backdrop to show off garden sculptures, especially with grasses with fluffy heads that’ll gently sway in the slightest breeze. They’ll provide a beautiful contrast to straight lines and spheres.

Cut and dry some of the seedheads in autumn for indoor arrangements or leave them where they are to feed finches and other seed-eating garden birds.
