Flowering now - narcissus cyclamineus hybrids

If ever there was a reason to learn how to grow plants from seed, these little charmers are it. You can’t expect to buy these from your local plant shop. In common language, dwarf daffodils or botanically, narcissus cyclamineus. That last word just means that they are part of the group where the skirt of petals is completely reflexed as if the flower is a force 10 gale. In the wild they come from north west Portugal and Spain and are endangered. They are not endangered in our garden where we love them for winter cheer, though many that we grow are hybrids. They are classified as dwarf, not miniature, because they are on stems around 15 to 20cm long. Flowering long before the large, modern daffodils, we find they are nowhere near as susceptible to the nasty narcissi fly which can lay its eggs in the crown of the bulb (so the larvae hatch and eat out the bulb). The silver leafed plants beside are a wide leafed hybrid of our native mountain daisy or celmisia.

From meadows to motorway sidings with the classic border inbetween (part 4 English summer gardens)

Note: this follows on from the earlier column: English Summer Gardens – part 3.

I wrote two weeks ago about the English summer garden being a continuum stretching from natural meadows through to plantings on the sides of motorways or NZ traffic islands. I was gently drifting my way along this journey until I reached my word limit around the classic English country garden as exemplified by Penelope Hobhouse and the late Rosemary Verey. I had to stop there because suddenly there is a great big punctuation point with the late Christopher Lloyd at Great Dixter.

Great Dixter can be controversial. Mark stood in the garden and commented that it was a bit like an ongoing negotiation with nature. At its best, it is gifted and has clearly had an enormous influence on the direction taken in many New Zealand gardens. In the middle it can be somewhat serendipitous, but there are parts where there is a suspicion of the emperor’s new clothes. As a garden it sits between the meadow gardening–wildflower end of the spectrum which relies on a great deal of self seeding (and good chance) and the controlled Edwardian arts and crafts style synonymous with Edwin Lutyens and Gertrude Jekyll. Christopher Lloyd experimented all his life but his legacy to modern gardening is arguably the mixed border (using shrubs and clumping perennials in tandem and brave colour combinations) and the managed meadow. In New Zealand, we seized on the mixed border as if it was our own but alas it is not often carried out with the panache of Christo Lloyd and is frequently rather dull.

Historically Lutyens and Jekyll pre-dated Christo Lloyd and in fact Lutyens redesigned Great Dixter for the Lloyd parents. But on my continuum, they are more to the ordered and managed side. We travelled in part to see their legacy. Famous examples are Sissinghurst and Hestercomb but we also visited lesser known gardens. The spirit of the Lutyens-Jekyll style was formal landscaping by Lutyens in the Arts and Crafts mode (confined and defined spaces of the garden room type), softened by sweeping plantings designed by Jekyll. If you imagine beautiful stone work, clipped hedging, masses of blue delphiniums, extravagant fluffy pink peonies, pink and white roses and drifts of underplanting such as lambs’ ears (stachys), you will be on the right wavelength. It is very pretty although the borders and beds could be a bit on the narrow and busy side and it can get a little formulaic when you see a number of such gardens in a row. I suspect that it may be a little dated now. Certainly the very narrow borders worried me and I would want to rip them out. Keep the trademark Lutyens rounded stone steps, though. Nobody does steps like Lutyens.

Fortunately it was towards the end of our trip that we ended up at Wisley because there we saw a range of garden styles which gave us the framework to make sense of what we had seen.

Gifted and unusual colour combinations at Hyde Hall

Gifted and unusual colour combinations at Hyde Hall

Cue in the classic long border. Yes Great Dixter has one but Wisley sets the standard. Hyde Hall has a shorter long border divided into colour segments. Lots of gardens have the long border. At its Wisley splendour, it is two parallel borders with a wide grassy path between and we are talking a hundred and thirty metres long, each, and (here is the rub for many home gardeners) six metres wide. Beth Chatto’s garden is a whole series of freeform borders which curve and flow but are still following the principles of the long border. Such borders are often planted on terrain contoured to give extra height at the back. Because they froth out at the front (alchemilla mollis is a great favourite to achieve this effect and seems to be regarded as colour neutral), there is often a boundary of wide pavers defining the edge. This stops the frothing from killing the grass. Generally plants are layered from tallest at the back to lowest at the front and the crux of this type of planting is combinations of plant foliage and flower throughout the season. There is no mass planting. Many plants will need staking and deadheading and it is all extremely labour intensive. You need plenty of space for this type of voluptuous display.

For us, this is the zenith of summer gardening. On the days we visited, we ranked Beth Chatto top of the list for plant combinations and quality management of this intensive style of gardening, Hyde Hall top in genuinely original colour and flower combinations and Wisley all round top in the total package of scale, design, plant combinations and management.

But, Wisley does not stop at the long borders. Dutch designer Piet Oudolf has moved herbaceous planting on a few steps and, in front of the spectacular new glasshouse, Tom Stuart-Smith has taken it further. There is an element of modern pragmatism and indeed we were told that the new borders only require a third of the input of the traditional long borders and that is a huge difference. The Oudolf borders have attracted both praise and criticism. They are a great deal more controlled. The plant palette is restricted and most of the plants chosen do not require staking (or, I think, regular dead heading) and they are pretty much of a standard height. But it is not mass planting and the skill of striking plant combinations remains to the fore. Oudolf has worked with parallel borders again but used different plant combos in rivers flowing across, more or less in diagonal lines when viewed from above. Each river is comprised of three or four different types of plants.

Tom Stuart Smith has further refined the Oudolf technique, bringing it together with the sweeps of colour first espoused by Gertrude Jekyll and the prairie meadow concept currently in vogue to give grand sweeps of herbaceous plantings for the larger canvas. Much of the detail and complexity of the long borders has now gone, as has the need for intensive maintenance. But plantsmanship and design lifts it well above utility mass planting and while it may not appeal for smaller scale domestic gardens, it is a modern and more practical approach for public plantings.

So how do we end up at the traffic islands filled with tussock or the motorway sidings of utility clumpy plants? Take the simpler blocks of colour planting done by Tom Stuart-Smith. Eliminate any plants that are pink flowered (not fashionable), anything that is deciduous (need foliage 12 months of the year), anything that is grown more for its flowers than its foliage, anything that requires more than a very occasional clean up. You are left with reliable, utility, evergreen clumping perennials which in recent years have become the repertoire of many landscapers for mass plantings – the liriopes, mondo grass, ligularia type of plant. Now reduce the range further. Take out any plants which are less than 30cm high, any plants which require good soil conditions or shelter, any plants which look sufficiently desirable to be stolen, and any plants which are not available dirt cheap and preferably from a native plant supplier or prison nursery. You are left with mostly tough grassy type plants which on their own are as dull as ditchwater. It is the end of the road.

  • Temperatures are inexorably creeping upwards and that means an explosion of slugs and snails. Waitara gardener, Alathea Armstrong reports that she caught no fewer than twenty of them partying and feasting on her emerging delphiniums. If you choose to use slug bait, remember that one bait can kill several. Reduce the danger to birds and hedgehogs (nature’s controls) and to pets by never spreading it thickly like fertiliser. Placing a bait or maybe two under a shell or a lid will keep the bait active and out of the way. Slug bait is designed to attract the targets which is why you do not need to carpet the garden hoping they will trip over it. Keep your packet of slug bait somewhere safe too and don’t leave it on the door step. Always wash your hands after touching it.
  • To avoid using toxic baits, get out with a torch for night time sport and reduce the population. Use a thick spread of cheap baking bran around special plants. Mulch with pine or rimu needles. Create a circle of sand, sawdust or egg shells around vulnerable plants. Place hollowed out citrus shells to provide a house for them (and don’t forget to do a terminator round each morning) or leave a partially buried, half empty can of beer to attract them. Stay on top of the problem from the start, which is now.
  • As sasanqua camellias finish flowering, it is time to trim and shape them. If you want to have a go at some creative pruning or topiary, sasanqua camellias are a good starting point. If you make a bad mistake, fresh foliage will hide it within a fairly short space of time. If you get it right, a shaped and trimmed mature camellia can be a wonderful feature plant and act like a punctuation point in the garden.
  • There is evidence that marigolds can repel some of the pesky insect infestations in the vegetable garden, although it is unlikely that one or two plants will do much. You probably need lots of them. However, they will feed good butterflies like monarchs and can be dug in as a green crop later so it is worth a try. Sow them from seed now. It is miles cheaper than paying for a nursery to produce a punnet of half a dozen plants for you. Tagetes are the recommended marigold family for this purpose though there is some evidence that calendula will work too.
  • If you are wanting to plant fruit trees, don’t procrastinate. While there is plenty of time left for planting, garden centres will have their largest selection available now and if you hang about too long, sure as eggs they will sell out of the ones you want. Hawera Plum, Apricot Fitzroy and Monty’s apple are all local(ish) selections.
  • In the veg garden you may like to get fennel seeds in now for an all round useful and long lived new vegetable. It is not bullet proof as a crop but its harvest is certainly useful. Dig in green crops.

  • A few mild days mid week were the klaxon heralding spring. In New Plymouth if you look to the right as you drive along Powderham Street between the radio station and the well known liquor store, you will see the campbellii magnolias in all their glory. These are the first of the season to flower every year. Our English snowdrops are starting to pass over and the dwarf daffodils are flowering their little heads off. It is very much countdown to spring. Be prepared for some relapses to miserable, bleak weather as well.
  • It is still garlic planting season but don’t leave it too much longer.
  • Don’t delay on pruning grapevines because the sap will start to move soon and they weep and bleed if you prune too late. However there is no harm in taking a little longer on the roses, wisteria, clematis and hydrangeas.
  • If you are enjoying eating the yellow kiwifruit and want to grow a vine, you will need to try it from your own seed. As far as we know, the fruit you buy in the shops all comes from cultivars still owned by the plant breeders [Hort Research] and not available to buy for the home gardener. There is, however, nothing to stop you from trying your own from seed although there is no guarantee you will get a top cropping one from seed. Mark has several plants which he raised and we will be planting them out in the field to see which is worth keeping. Just use seed from a good specimen of fruit you have bought.
  • Continue sowing broad beans. If you don’t think you like them, try eating them at the juvenile stage and you may become a convert. They are a most useful spring bean and, as an experienced veg gardener noted, once you have harvested the beans, the remaining plant makes a wonderful green crop for digging in to the garden..
  • The optimum time for feeding plants is just as they are about to go into growth which is… [wait for it….drumroll…] now – for most plants. Prune, clean up the garden beds, feed and get mulch on. The mulch is really important if you have poor soils and if you dry out easily in late spring. We still advocate blood and bone or Bioboost as garden fertiliser. Leave the plastic coated prills (Osmocote, Nutricote, Plantacote type) for container plants and don’t waste your money using them in the garden.
  • If you have ugly, leggy or otherwise crusty looking rhododendron plants, now is the time to cut them hard back. For brutal pruning back to bare woody trunk and stems, don’t delay. You are going to shock the plant and you want to maximise its new growth so sacrifice this year’s flowers. Cut back hard, feed and mulch. It won’t flower next year but you should have a really attractive, renovated plant which is bushy and fresh. No guarantees – it is kill or cure with sick plants. You can cut all the foliage off on both rhodos and camellias but only at this time of the year.

English Summer Gardens – Part 3

We went to England to look at summer gardens which are all about flowers, particularly perennials and annuals. We didn’t expect to see so many meadow gardens and nor did we have the perspective of the summer garden as a continuum.

At one end, we saw natural wildflower fields, grazed by sheep and not managed as gardens at all. There are two key aspects to understanding British meadows. One is that many of our weeds in this country are in fact wildflowers in their home environment. So what might be seen as a rank, unloved and weedy infestation of dandelions, stinging nettle, daisies, convolvulus and blackberry is an entirely appropriate and acceptable meadow garden in its natural setting. Add in other elements such as cowslips and wild orchids (dactylorhizas and anacamptis pyramidalus) and you have something altogether delightful. The second aspect is that wild flowers thrive in a climate that is cold enough to stop all growth in winter and dry enough to stunt most growth in summer. These are hardly typical Taranaki conditions.

Inch along the continuum and you discover managed meadow gardens which were integral to most of the large gardens we visited. The late Christopher Lloyd of Great Dixter was an influential figure in popularising and enriching the meadow garden genre by encouraging a wider range of wild flowers to naturalise. The general rule of thumb for managing meadow gardens is to cut the meadow down in August (the equivalent of February or March in our hemisphere) and to leave it lying for about three weeks. This allows the seed to distribute. The hay is then raked off the meadow in order to keep the fertility low. If the soil is too rich, the growth becomes rampant and grasses will dominate. The existence of a parasitic annual referred to as Yellow Rattle (Rhinanthus major) helps to keep the grasses weakened.

Meadow gardens appeal to the romantic and naturalistic instinct cherished by the English. It is not seen at all as scruffy or unkempt and it is fine to have a designated meadow area as your main point of entry to the garden. The naturalism is often combined effectively with that most prim and proper of all gardening techniques – topiary. Great Dixter does it – the large clipped yew shapes created by Lloyd Senior now stand in the midst of an informal meadow. At Helmingham Hall in East Anglia, an undulating wave of pathway is cut through meadow grasses which surround large clipped yew domes.

I don’t see many New Zealand gardeners managing this meadow genre. Our soil fertility is too high, our grasses grow too strongly and will choke out most competition, our torrential rains will flatten meadows even in summer and if the rain doesn’t do it first, then winds will. Our nitrogen levels are too high. And we tend to be a bit anally retentive and suburban, dedicated to manicured lawns and edges, let alone to glyphosate, to tolerate the casual live and let live philosophy of the meadow.

Take another step along the continuum and there is the completely contrived and totally enchanting field of flowers (without grasses). We saw this done at East Ruston Old Vicarage Garden where the field of yellow daisies had hints of blue cornflowers and red soldier poppies and it was so perfect that it took our breath away. If you start with bare earth, in the first season there are no competing grasses or weeds so all that is seen are the desired annuals. By the second season, competing plants mean that you are closer to the managed meadow situation.

We are now moving into a style of gardening which has a debt to the North American prairies and the prairie meadow style reaches a pinnacle at Wisley Gardens where Professor James Hitchmough from the University of Sheffield is responsible for one of the most delightful meadow gardens of perennial flowers that you will ever see. Apparently the inspiration was Missouri meadows but the execution of the vision was achieved with gardening skills. The brief included a requirement that this garden be easily managed by Wisley staff so it went in to an area which had been cleared of weeds and grasses and probably also cleared of much of its topsoil. A rope mesh mat was laid, allowing the plants to stay anchored and a carefully chosen palette of about ten plants from seed mixed with sawdust was sown to create a sea of perennial flowers. There wasn’t a lot of foliage evident and the plants were tough performers which thrived in hard, dry conditions. It was magic. It was also in its second season already and there was no evidence of weed or grass contamination although it must be said this is managed with some ongoing minor intervention.

Move along the continuum further and you get to the classic cottage garden style which the English made their own. Cottage gardening is an indulgence of self seeded annuals and perennials, usually combined with roses, along with other shrubs and climbers such as clematis. The effect is a riot of colour and flowers with nothing so contrived as colour toned borders or stage managed plant combinations. Plants should look as if they are growing naturally where the seed falls and hard landscaping takes a back seat in this informal, romantic look. Readers who know the Armstrong’s garden in Waitara will have seen a rare local example of this gardening genre. If you have yet to visit, go and see it this Rhododendron Festival. Alathea Armstrong has it peaking to perfection for that week and it is very pretty, albeit labour intensive.

But take another step along and you come to what I call the managed cottage garden look which I associate with English gardeners such as Rosemary Verey and Penelope Hobhouse. The romantic naturalism is now combined with hard landscaping, form and formality. It is much more controlled, as can be seen in the Hobhouse Country Garden at Wisley. Colour toning becomes a major factor. Deadheading becomes intensive in order to prolong the display. Planning for successional flowering from spring to autumn is important. Constant management means spent plants are cut back and holes are plugged by bringing in fresh potted colour from out the back somewhere. Weed management becomes more critical. Many of the plants need staking. We talked to Lady Xa Tollemarche at Helmingham Hall about her borders and she manages to keep them at a peak for several months. The English do this classic garden style so well but it is not for the home gardener who sees spending every spare minute in the garden as a form of slavery. Easy care and low maintenance, I think not.

We are, dear Reader, only half way along the continuum. How silly of me to think I could summarise all we saw and talked about in 1200 words. We need to pause in the middle before moving on next instalment through the mixed border a la Christopher Lloyd, the sweeps of herbaceous colour softening formal landscaping in the style made famous by the Lutyens-Jekyll partnership, moving through the classic and intensive long borders to the recent work of Piet Oudolf and Tom Stuart Smith and onwards to the modern minimalism of mass planting. There is still quite some distance to go and any number of points where thinking gardeners can hop off the continuum, comfortable that they have found the point that best suits their situation.
