Decorative grasses convey out the most effective in your border, contrasting and complementing the flowers.
However they had been thought of ‘trendy’. Consequently many people missed them.
Till now, they haven’t been a part of a standard herbaceous border.
However now we more and more respect that decorative grasses add mild, texture and motion to a border.
They’ve gone past ‘style’ and at the moment are perennial border staples. And they’re very simple to take care of.
I visited Paul Seaborne of Pelham Vegetation, who’s enthusiastic about grasses, to learn how to decide on and use them.
Pelham Vegetation is in Sussex, and his adjoining backyard has open days for the NGS. And Paul additionally sells his crops by way of the Plant Festivals Roadshow.
Listed here are seven sensible decorative grasses and easy methods to profit from them in your backyard.

Golden Oat Grass/Stipa Gigantea
Hardy to: Minus 23C/minus 10F
Paul grows Golden Oat Grass (Stipa gigantea) ‘Gold Fontaene’ in his cottage backyard. ‘Simply because it’s a tall grass, that doesn’t imply it must be in the back of a border,’ he says.
Place it on the entrance or at a nook. It’s tall, feathery stems are nearly see-through. He significantly likes to position it the place it may be backlit by the rising or setting solar.
Though it seems to be fragile, he says that the slender stems are fairly sturdy and resilient. The seed-heads empty quickly after flowering, however stay on the plant so that you get the complete impact of a decorative grass all through winter. A number of stems might collapse, however in any other case, minimize it to the bottom in spring.
Paul makes use of a hedge-trimmer, so the job takes only some minutes. And that’s the solely care the golden oat grass wants all yr!
Feather Reed Grass/Calamagrostis ‘Karl Foerster’
Hardy to: Minus 40C/minus 40F. 1.5m-1.8m excessive
Calamagrostis ‘Karl Foerster’ is beloved by backyard designers in all places. It is vitally straight and upright, forming columns of golden grass from summer time by way of to winter.
I’ve seen it used as a ‘hedge’, the place it gives the look of a row of troopers on parade.
Paul used to have evergreen shrub columns in one in every of his borders. However he felt they dominated the borders, so he took them out and used Calamagrostis ‘Karl Foerster’ as a punctuation level as a substitute.
That is additionally a tall grass, however it’s fairly slender so it’s appropriate for the center or again of a border.
Chinese language Silver Grass/Miscanthus sinensis ‘Yakushima Dwarf’
Hardy to: There are numerous forms of miscanthus and hardiness varies. ‘Yakushima Dwarf’ is hardy to Minus 28C/minus 20F
There are numerous sizes and forms of Miscanthus or Chinese language Silver Grass. Heights range from 60cm/2ft to 1.8m/6ft.
Paul’s ‘Yakushima Dwarf’ is about waist-high and he makes use of it as a hedge.
Decorative grasses make good hedges as a result of they filter wind, however don’t take an excessive amount of moisture or nutrient from the soil.
The one drawback is that Miscanthus should not year-round. It’s best to minimize them right down to the bottom every year in spring. Nevertheless, they develop up shortly and supply motion and construction in late summer time and over the winter.
Miscanthus additionally make good punctuation factors – on a nook, within the center, entrance or again of a border, relying on the peak.
Clear Moor Grass/Molinia ‘Clear’
Hardy to: Minus 28C/minus 20F. Hieght 1.5m-2.5m
This can be a very clear grass. It is vitally tall and ethereal, however Paul recommends placing it on the entrance of a border or on a nook, as a result of it doesn’t block something.
You may see all of your flowers by way of it, so it provides texture and motion to a backyard.
This grass seems to be good from summer time till the primary frost. After that, its stems collapse. ‘And also you clear all of it away,’ says Paul.
The next spring Molinia ‘Clear’ will develop up once more. So it’s just about maintenance-free, other than clearing away the lifeless stems every year!
Fountain Grass/Pennisetum ‘Black Magnificence’
Hardy to: there are numerous forms of pennisetum so hardiness varies. ‘Black Magnificence’ right down to minus 28C/minus20F. Peak 80cm-1.5m
There are numerous forms of pennisetum, however ‘Black Magnificence’ is one in every of Paul’s favourites. ‘It’s a lump of grass, so it must be on the entrance edge or to dominate its place. Put smooth planting round it.’
This wants ‘good mild and a very good depth of soil. It may be fairly a thirsty plant.’ Many decorative grasses are good for ‘dry gardens’ or gravel gardens, however not this one.
Reduce right down to the bottom every year in spring.
Pheasant’s Tail Grass/Anemanthele lessoniana
Hardy to minus 6C/21F. Peak 90cm/3ft
One other backyard designer favorite. Not like many grasses, that is good in partial shade, though it additionally likes full solar. Has pretty autumn color.
That is thought of partially evergreen, so don’t minimize it right down to the bottom. Comb out the lifeless leaves with gloved arms.
Good on the entrance of a raised border, because it arches gracefully to the bottom.
Japanese Forest Grass/Hakonechloa Macra
Hardy to minus 28C/minus 20F. Peak 30cm-50cm
This low-growing grass is well-liked for mild shade, however don’t over-crowd the border when it’s getting established. It’s additionally fairly drought-resistant however will want watering in its first yr.
Paul grows it beneath a cornus and beside a hedge, alongside hardy geraniums, so it’s a helpful floor cowl plant.
It’s additionally good in pots and containers, as are most grasses. (The very tall ones are extra weak to the wind in pots.)

Ought to decorative grasses be in the reduction of yearly?
Firstly, discover out in case your decorative grass is evergreen or deciduous.
Deciduous decorative grasses often change color within the autumn, then many offers you sculptural dried seedheads and stems all through winter. These grasses want chopping to the bottom each spring.
Examine the care directions in your selection. In the event you minimize the extra tender grasses too early, a frost might get to the plant. However in any other case it’s easy!
In case your decorative grass is evergreen, then the leaves will keep inexperienced or primarily inexperienced all year long. A number of the leaves will change color and die off, so you’re going to get a stippled impact.
Many of the evergreen grasses ought to NOT be minimize down utterly to the bottom. Rake the lifeless leaves out or ‘comb’ by way of the grasses with a gloved hand.
You are able to do this in spring or at any time when the grass appears to have an excessive amount of lifeless in it.
