A garden of grasses. Mostly.

The grass garden at Bury Court

The grass garden at Bury Court

It is interesting to reflect on gardens over time. Sometimes a garden that makes you go ‘wow’ on the day is not the one that endures in the memory. In fact, not wanting to be too dismissive, but it is a rare garden that stays in the memory for long after a single visit.

The grass garden at Bury Court has endured for me. So much so, in fact, that it has inspired me to start a grass garden here.  Bury Court’s grass garden was by leading UK designer, Christopher Bradley-Hole but credit must also go to the garden owner, John Coke, whom we didn’t meet but had certainly stamped his mark on the other areas of the garden which were early Piet Oudolf. It is not that I want to recreate that grass garden which was full of soft, waving, tall grasses in informal plantings but contained within a sharp-edged, rectilinear design with a charming Japanese-influenced summer house at its centre. I am just using it as inspiration.

Anybody who has looked at gardens in the UK and Northern Europe over the past decade or maybe nearing two, will have seen the extensive use of grasses in perennial plantings. It is variously described as ‘prairie planting’, ‘New Perennials’, ‘naturalistic gardening’, ‘Sheffield School style’, ‘Oudolf- inspired’ and, no doubt, other terms as well. The bottom line is that it is the integration of grasses with flowering perennials in various styles and combinations and it has yet to catch on in New Zealand. Towards the end of our last trip in 2014, we started counting the ratios and it was common to see 3:1 – three flowering perennials to one grass. The Bury Court grass garden was 1:8 – that is one flowering perennial to eight grasses. The effect was very different and the movement of the tall grasses a delight.

I have been incubating ideas for the past three years. In an old garden, it is rare for us to be in a position to start a new area from scratch but that opportunity has arisen. Somewhere over 250 square metres of empty space in full sun with good drainage, in fact, that I can get down on for my grass garden. But we need that amount of space for we envisage B I G grasses waving in the breeze and when each plant will take up probably a square metre, that chews up the space. We have enough highly detailed garden here already, so we are looking at bigger canvas garden pictures with lower maintenance. That is the plan, anyway.

We have been given some plants of Stipa gigantea, beloved by UK gardeners. It remains to be seen if it will perform in our conditions, but I have put the first nine plants out. Also our native toetoe (which used to be a cortaderia but has now been reclassified as an austroderia) which will grow here and is our native version of the pampas grass often used overseas. Pampas (Cortaderia selloana) is on the totally banned list where we live, be it pink or creamy pampas. I have a very large miscanthus that I will relocate and divide in winter and a few other different grasses we have gathered up over the years but never found a suitable spot for. In using some of our native grasses and the Australian lomandra, there is an immediate difference to what we have looked at overseas. For our grasses are evergreen and theirs are generally deciduous. That is a big difference. Deciduous grasses give a fresh new look every spring whereas evergreen grasses hold their dead leaves so they don’t look as pristine but they are present all year round.

In terms of flowers, it will be a restrained palette. Mark has raised a lot of Aurelian lilies (clear, bright yellows and few in orange) that flower in early January and are desperate for a forever home in the garden. They will be number one, planted in groups of five. I have no idea how many there are out in his vegetable garden waiting to be lifted – maybe 80 flowering sized bulbs or so?

For mid summer, the crocosmias can add spots of colour and I may use the pure red and pure yellow tigridias too. We have a giant, autumn flowering yellow salvia that towers over 2 metres high so needs big space. I think that will fit in. Self-seeding, towering fennel (I like fennel flower and seed heads), a tall, creamy yellow alstromeria and that might be it for the initial plantings. The grasses are to be the prime focus in this new area.

Being gardeners, not designers, we are working from gut instinct and experience, not a formal plan. We are debating about whether to turn it into a gravel garden by using fine gravel as both mulch and path surface but that is a bit further down the track. We happen to have a small mountain, almost a mountain range, even, of fine gravel that would be suitable if we decide that is a good idea.

It is not instant gardening. Because it is dependent on plants, not hard landscape features, it will take time to fill in and mature. But that is in the nature of long term gardening – gradual evolution rather than instant gratification.

And a weedy carex - at least we think it is a carex, that we are hand digging to remove from both the new garden and the park. Decorative seed heads but way too badly behaved and invasive

Postscript: A Facebook follower says of that weedy carex above: “Eek, that weed is a Cyperus eragrostis ( I think) type of sedge.” We are in complete agreement that it is a menace.
