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.

Weeding the stream. Again. An ongoing task.

“Believe me, my young friend, there is nothing – absolutely nothing – half so much worth doing as simply messing about in boats.”

Kenneth Grahame, The Wind in the Willows

I misremembered. I felt sure there was a Wind in the Willows quote about messing about in the muddy waters of a stream but I was wrong. Of course they were messing about in a boat, not mud. When I went searching, there were many other charming quotes from the same book which are gently affirming in a world seemingly gone mad, but I found another escape this week.
img_3982I have been weeding the stream. Yes, hand weeding the stream. I see it is five years since I last got down and dirty in the water, although Mark and Lloyd do a certain amount of ongoing maintenance with the long handled rake. I find it easier to climb right in and scoop by hand or sometimes with a rake. It is very muddy and Mark laughs when I stagger back up from the park but I am way too vain (or self conscious, maybe) to immortalise this by taking a selfie of Muddy Me.

There are both eels and fish in the stream – small fish, mostly mud fish – and I find it deeply unnerving when something smooth and slippery brushes past my bare legs. I wouldn’t be quite so anxious were it not for Mark’s recent encounter with an eel. He was reaching into the water to pull out some blockage when an eel mistook his hand for something else and latched on. There was blood, quite a lot of blood and all of it was Mark’s. Eels are renowned for their backward facing teeth so it is not easy to dislodge them, though I think both the eel and Mark got such a fright that everything went flying. I console myself with the thought that eels are not known for aggressive attacks and it would be bad luck for one to follow up with me so soon after. Just in case, I wear both shoes and gloves as a precaution. I am hoping one will not attack my knees, calves or thighs.  Still, as I reviewed one cleaned area of the stream a few hours later, I was disquieted to see an eel gently swimming along the somewhat bare expanse. But it was a small one and I will not be intimidated.

But the weeds! We get up close and personal with the weeds that are carried down to us from properties further upstream but the major flood in 2015 has caused us a few more problems than before. Crocosmia, often referred to as montbretia but technically crocosmia x crocosmiiflora, have pretty summer flowers but the huge flood carried the corms far and wide and we are now working on restricting its spread. There is simply too much of it for us to be able to eradicate it and we would get reinfested during the next flood event.

Eradication, however, is the aim with the dreaded Wandering Jew (Tradescantia fluminensis). Mark has spent two decades battling this on our properties but still we get new outbreaks washed down to us. The problem is that every piece that is broken off is capable of growing and it is truly rampant once established. Both the tradescantia and the crocosmia grow alongside the water, rather than in it.

The goal is also to eradicate the oxygen weed and the Cape Pond Weed (Aponogetum distachyum). Mark has succeeded once in eradicating oxygen weed so he was most disappointed when he saw a larger form of it getting established on our place. His theory is that it comes from people emptying their little aquariums into fresh water ways, presumably because they do not wish to euthanise their goldfish and can’t find anyone to give them too. Don’t. Please don’t ever do this. Not only do we not need or want free range goldfish in our waterways, the oxygen weed becomes a choking blanket in slow moving fresh water. We have spent countless hours pulling it out but unless we get every bit, it will grow again. Ditto the Cape Pond Weed, about which I have written several times in the past.

What I call the blanket weed – a mass of very fine filaments – is here to stay but we try to keep it from getting too solid and impeding the flow of water. It is at least easy to rake out. Besides, the aquatic life needs some cover.

We are not perfect. Although we try and dead head our waterside irises and primulas, some of those may have washed downstream. I did at least go to a lot of effort to get rid of the noxious flag iris beside and in the water when we realised what an environmental hazard it is in this country.

In the meantime, there are worse ways to spend a pleasant, mild day than poddling about in the water. Our adult son is returning home from overseas next week and plans to stay for a few weeks. He spent many childhood hours playing with his mates in the ponds and the stream  – boogie boarding up and down and playing bike jumping games into the water. I am wondering at what stage I might suggest to him that it would be a huge help to his Aged Parents if he could turn his attention to scooping or raking the weeds from the deepest sections of the ponds which are beyond my reach. We shall see.

As you drive around the countryside in January, ponder this: does a sprayed roadside with dead grass and roadside litter look better than wildflowers? And are garden escapes (which takes in most roadside plants and flowers) environmentally worse than repeated application of weedkiller? Maybe it is time we reviewed our attitude to weeds.

It is often said that a weed is simply a plant in the wrong place, though I see Sara Stein is attributed with the extended statement, “A weed is a plant that is not only in the wrong place, but intends to stay.” After all, even weeds are native to somewhere and one country’s treasure can be another country’s problem.

A disclaimer first: our native bush and forest are precious and vulnerable to takeover by invasive and aggressive imports. We do not need another old man’s beard (Clematis vitalba) and perish the thought that Japanese knotweed (Fallopia japonica) ever gets a major foothold here. If you are lucky enough to live adjacent to near-pristine native bush, that brings an obligation to be very careful with what escapes your property and colonises roadsides. It also behoves us all to have some awareness of what is on our Regional Council banned and watch lists.

But most of us live in heavily modified environments and I suspect a preference for weedkiller over wildflowers arose from our farming heritage and feeling of obligation that “weeds” should not be permitted to invade precious farmland. Nowadays, when farming has become much more industrialised – a green desert, often, lacking even shelter belts – based entirely on imported grass and feed species, I don’t think that argument holds.

The ugliness of the sprayed  verge

The ugliness of the sprayed verge

Each time we visit Britain, we are entranced by their hedgerows and natural roadside vegetation. Apparently, after major clearance in decades past, there came an awareness that hedgerows contribute a great deal to the eco-system and grants were made available to reinstate them. There is not widespread mowing of road verges, let alone the ugliness of spraying. Would that we had such an enlightened attitude here. In vain do we protest that repeated spraying creates a vacuum into which unwanted weeds move first (notably the invasive, yellow bristle grass in Tikorangi), but it also prevents the ground from absorbing rainfall. Instead, the surface water is funnelled down drainage ditches, washing with it weed spray and any petrol residue from the road into waterways. How much better to have a growing roadside which filters the run-off?

Crocosmia - weed or woldflower?

Crocosmia – weed or woldflower?

Roadside vegetation is more interesting visually too, offering flowers and seasonal colour. Add to that a wildlife corridor role and we argue that they can make a significant contribution to a healthy environment. If you are worried about using imported ornamentals, you can encourage native re-vegetation. The native plantings alongside the new Waikato Expressway feature an abundance of toetoe which is wonderfully sculptural and interesting, especially silhouetted against the sky.

But we like the random mix of plants and colours we see. I look for the point where wild hydrangeas on the Otorohanga bypass change from blue tones to pink tones. I guess that marks the transition to limestone country. All our hydrangeas in Taranaki are blue as blue and they thrive on roadsides in a climate where we get summer rainfall.

005The white Japanese anemones that flower in the long grass around the country corner where we live make me smile every autumn. Orange-red crocosmia – earlier referred to as montbretia – feature large around here. So too do red hot pokers, fennel, arum lilies and cannas while further north the ox-eye daises, yellow vetch and wild carrot feature more.

012And agapanthus. There is a plant that is a great deal more revered overseas than here. It is controversial, actively discouraged and some forms banned in northern regions. Some folk hate it with a passion and it cannot be sprayed out with glyphosate. But truly, our roadsides round here would be the poorer without the summer display. In its defence, we have not seen this tough plant seed down any great distance from its parent in our conditions and it is also very good at stabilising clay banks.

I recall two English garden visitors a few years ago who asked what were the “giant bluebell and what looks like a lace-cap yellow hydrangea” flowering on all our roadsides. The yellow lace-cap was fennel but the giant bluebell had me absolutely stumped until I next drove out. It immediately dawned on me that they were referring to agapanthus. It is not cold-hardy in large parts of Europe and the UK and is a prized garden plant. No wonder they failed to identify it growing wild in abundance here.

The sad state of Camellia chyrsantha

The sad state of Camellia chyrsantha

Tikorangi Notes; Friday 27 January, 2012

It was only last year that I featured one of the best flowerings we have had on Camellia chyrsantha (it of the butter yellow flowers – bright New Zealand butter at that). It only took a decade or two to start performing well. Alas, it came off second best to the rapid descent of a massive old pear tree last week. The trouble is that it is a grafted plant and the trunk has been split. We are hoping it may still recover and live to bloom again. We can take the long view and wait another decade, if need be.

I have been photographing the different bulbs flowering this month. We were worried we had lost the yellow-orange form of crocosmia but it has leapt into flower and is remarkably showy with very large blooms. The red form (the one above is a hybrid called Lucifer) is such a strong grower that the chances of losing it are negligible, which means we take it completely for granted. Indeed, red crocosmia is a widespread roadside flower regarded as an invasive weed and known as montbretia in our area. The pink vallota is also looking particularly fetching. I would describe it more as peach than pink. There appears to be some debate about whether it is a vallota or a cyrtanthus so the pink vallota may in fact be the peach cyrtanthus. The auratum lilies are still fattening buds and not yet in full stride – just some tasters open so far.

The pink vallota. Or should that be the peach cyrtanthus?
