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.

Wispy, pale and compact
www.thompson-morgan.com
'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.

Grey-blue fades to brown
www.thompson-morgan.com
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.

We can't get enough of this fluffy Pennisetum villosum with flowers of whitish-green that take on purple tints as they mature.

Whimsical, cottage feel

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.

Oat-like flowerheads
www.crocus.co.uk
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

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.

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.
