The plant breeder’s garden

“It’s very white out there,” he said

“It is very white out there,” Mark observed. We were standing in the roller door of our large shed, sheltering from another rainy squall and looking out to the new summer perennial gardens. The photo doesn’t fully convey the white experience. The row of Fairy Magnolia White, Camellia yuhsienensis and Mark’s hedges of michelia seedlings were all in view. Mark was envisaging a carpet of snowdrops at ground level as well, even though they are but a fleeting delight. I was looking at the michelia seedlings.

Mark has planted two sides of the new garden area in michelia hedges. Technically – in accurate nomenclature – these are all magnolias now but we continue to use the earlier term ‘michelia’ for the sake of clarity. When we say ‘magnolia’ here, we are almost always referring to deciduous magnolia trees so it is confusing to include the world of evergreen michelias which also feature very large in our lives at this time of the year.

Some of the seedlings are simply gorgeous but won’t be named

When planting seedlings, it means every plant will be different. For the largest length of visible hedge, he planted out one particular cross that had not come out as he hoped because very few were coloured. The nature of the parentage means that they will flower well, not grow out of control and be suited to clipping but they will never have the precision of planting a row that is all one clone – in other words, identical to each other. Mark likes seedlings for mass plantings because it adds interest to have them all similar but not identical.

Others are pretty on their day but floppy blooms don’t cut the mustard

I paced along his hedging, estimating how many individual plants there are. Getting close to 200, was the answer, planted at about 30cm spacings because we want a quick hedge that can be trimmed as required. Each individual plant in bloom is lovely on its day but some are lovelier than others. However, none will be named and put into commercial production. Mark has already named Fairy Magnolia White and Fairy Magnolia Cream and he won’t name any more white or cream ones unless there is something that is radically different or a major improvement. So these are ours to enjoy alone.

Heading into pink 

Part of a breeding breakthrough in colour but not good enough to select

At one end, there are about three different pink-toned varieties which are something of an oddity in amongst the cream and white majority. Again, he has already named Fairy Magnolia Blush in this colour range so they will just stay as a quirky aberration in the hedge at flowering time. We are okay with quirks.

Hardy michelias are basically white or cream. While there are new tropical species still being discovered and some of those show more colour, Mark has no interest in trying to breed with them, even if we could get them into the country to work with. Most of the michelias are not overly hardy at the best of times and he has been trying to get hardier selections (will they grow well and flower consistently in places like the UK, is one of his measures) without introducing more tropical genes. But he has managed to get as far as pinks, purples and primrose yellow by ever more complex crosses using the material he has available.

From white through to pinks and purples with a few heading into pale yellow –  blooms from the breeding programme

I see it was four years ago that I set out to pick a representation of single blooms from his seedlings to show the range in colour, flower size and shape that he has reached in what is predominantly a white or cream plant genus. While he has continued to flower more since, this photo remains a fair summary. We have selected three new ones that are currently in propagation and performance trials for probable release but there is a whole lot more to selecting a plant than the just flowers. My lips are sealed as to what makes these three worth singling out until we are further down the track of commercial trials.

Fairy Magnolia Cream just coming into flower

In case you are interested in what goes into selecting a plant (or you want to name something you have found), off the top of my head, the checklist includes the following:

  • Is it either distinctively different or a major improvement to similar plants already on the market? (This is arguably the single most important criterion).
  • Are there plenty of flowers? How long is the flowering season (some can be a short flash in the pan)? Does it flower consistently well every year?
  • Are the blooms reasonably weather hardy?
  • If it is scented genus, are the flowers fragrant?
  • Do the blooms age gracefully and fall cleanly?
  • Is the foliage as good as the flowers?
  • Is the foliage in proportion to the flowers?
  • Where do the leaf buds open from? In the case of michelias, does it just set leaf buds on the tips (in which case it will look leggy and bare very soon) or does it set leaf buds right down the stem.
  • Does it ever defoliate in a wet spring (a feature of Magnolia laevifolia formerly known as Michelia yunnanensis)?
  • What is its performance like as a garden plant , not just grown in a container? It takes several years to make this assessment. In the longer term, will it stay a garden-friendly size? Does it take pruning, trimming or clipping well?
  • What is its international potential? How is it likely to perform in more extreme climates?

Only then do the propagation trials start. There is no point at all in selecting a plant that is difficult to propagate, where the percentage of cuttings that do not set roots is too high, where plants *whiff off* – Mark’s phrase meaning die – during production, or where very particular propagation and growing techniques are required for success – growers just do not want to put the time and expense into growing plants that are unreliable or too picky.

New releases used to be the life blood of our mailorder business. Some selections stood the test of time, others not so much. At least all the magnolias have proven to be worthwhile. It is the vireya rhododendron selections and a few of the camellias that have fallen off the Jury plant wagon. These days, we get a new plant through the initial selection and then we hand it over to our agents to manage through final trials and then getting it to market.

It is a long path to getting a new cultivar onto the market. But in the process, we get a lot of unique plant material to use in our own garden.

Magnolia doltsopa syn Michelia doltsopa – a selection released as ‘Rusty” by nurseryman, Peter Cave. Pretty flowers but showing typical floppy tendencies of this species and the original plant in our park is massive.

Tikorangi notes: narcissi, garden edgings and a happy plant breeder

The snowdrop season is all but over already. It is charming but brief. The narcissi, however, have a longer season, at least in part because we can grow a much wider range of species and hybrids. Yesterday felt like a winter’s day – the last gasp of winter, I hope – so I headed out to pick one each of the many different varieties in flower. We don’t grow many of the larger ones at all, preferring the charm of the littlies, the dwarf ones. Bigger may be better when it comes to magnolias – at least in our eyes – but daintiness wins with the narcissi. Most of these are named varieties though Mark is also raising cyclamineus seedlings to build up numbers for planting out and to get some seedling variation within them. The cyclamineus are the ones where the petal skirt sweeps back, sometimes completely reflexed, giving them a slightly startled appearance. He was intending to plant many of these down in the park but hadn’t got around to it so offered them to me for the new grass garden.

Drifting dwarf narcissi through the new grass garden. Camellia Fairy Blush hedge and Fairy Magnolia White edge the garden on both long sides. 

I have now compromised the big, bold, chunky planting in waves that is the hallmark of the new grass gardens by drifting hundreds of dainty, dwarf narcissi through them – though far enough out to escape being swamped by the large plants, for several years at least. It adds seasonal interest to an area that will not come alive again until later in spring.

Informal bark edging and bark and leaf mulch define the garden area

After much consideration as to how we wanted to complete the grass garden with regard to edging, mulch and path surfaces, we have gone for the casual, organic and local options. As soon as I started to load in the wood and leaf mulch that a local arborist delivered, I realised that the beds would need an edging to hold the mulch from spilling over. My idea of a seamless transition between bed and path was not going to work. We have pine bark to hand – left over from getting the firewood out from a fallen pine tree so I am constructing small edges out of that. It lasts for many years. The paths are still bare earth (we will probably use granulated bark on those) but as soon as I made the edgings and laid the mulch, it took on the appearance of a garden. It is a casual look but one that sits easily with us with the benefit of being low cost and, as Mark keeps saying, the use of organic materials adds carbon to the soils.

I am laying the mulch on fairly thickly – around a forefinger in depth which I measured to be about 7cm. Because it is fluffy, it will compact to less than that but if I see any weeds coming through, I can top it up.

Fairy Magnolia White – not only a beautiful flower form but a very long flowering season, beautiful velvety buds, good foliage and perfume

Mark is a quiet man, not given to blowing his own trumpet, but sometimes I hear him murmur a comment of deep contentment at a plant he has bred and named. So it was this week as we looked at the avenue of Fairy Magnolia White and Camellia Fairy Blush. “I picked White because it had a pretty flower,” he said. And it does. In a world of floppy white and cream M. doltsopa flowers, Fairy Magnolia White stands out with its beautiful star form. There were a lot of very similar sister seedlings to choose from in that cross and as a breeder, he always worries whether he picked the best one. I think he finally decided that he had indeed chosen the best which is just as well, when you think about it, because he will only ever name and release one of that cross

Camellia Fairy Blush also has a long flowering season, drops its spent flowers cleanly and clips well

Camellia Fairy Blush, planted as a hedge beneath the two avenues of Fairy Magnolia White, is also a continuing source of satisfaction and delight to us, even if it is a constant reminder of a missed commercial opportunity. It was the first camellia he ever named and sold. Back in those days, protecting a plant as our intellectual property was not even on the radar and now Fairy Blush is sold widely throughout the world and few know that it originated here and was Mark’s selection. We have even seen it branded overseas with other nursery names but we know it is ours. That is life and it is a very good camellia and continues to be a source of pride and pleasure to the breeder.

Fairy Magnolia White and a very blue spring sky

On the right track, at least

I came across the sight of this bulb drift in town and had to stop and look more closely because it seemed so unexpected. It is on Marsland Hill, for local readers. All credit to Council for putting it in and braving local flower thieves, but as I walked around it, I thought it was a good example of how it could be more exciting. My photos are less than ideal, sorry, on account of my mobile phone being a cheap one with a utility camera.

The paperwhite narcissi are gorgeous and deliciously fragrant but they aren’t exactly mass flowering in comparison the amount of foliage. I think they may be interplanted with other varieties that will come into bloom later which is good planning. But if that is the case, the paperwhites could have been concentrated in maybe four separate clumps with others planted between. It would give more visual oomph.

The combination with Dutch iris is a really good idea. But the selection of a pale variety in pastel shades is a bit insipid from a distance, though pretty enough close up. I saw a blue bud and my eyes lit up. But when I found one open, it was not a good blue. In fact, I would deem it an awful colour combination of yellow, purple and brown that should never have been selected in the first place.

Purple, yellow and brown to the left… our blue to the right

I am no expert on Dutch iris and we don’t have many in the garden. But we do have a pretty blue. It was a bit coarse and out of scale in the rockery (they are not a plant of great refinement) so I relocated them to the new perennial borders where they are right at home, multiplying satisfyingly and putting on a pretty show at this time of late winter. And it is a much prettier blue than the murky mix of the one in the planting I was looking at.

I feel I am learning constantly so I enjoy analysing what I think works and doesn’t when it comes to plantings. And while this planting was sufficiently delightful to make me stop and turn the car around, I think it would have worked better with concentrated patches of paperwhite narcissi interplanted with purer blue Dutch iris. Now I am going to have to go back in the next few weeks to see what comes into bloom next and how it changes through the spring. I will take my good camera with me. And I do hope that rogue flower pickers leave it alone so we can all enjoy it.

From cob to cracker

Indian corn or flint corn

Really, I wanted to show the photo of Mark’s pretty corn cobs. This is commonly called Indian corn or flint corn. It is maize, not sweetcorn so not suitable for eating as corn on the cob. Modern sweetcorn is a very different crop after a great deal of selection to get strains with very high sugar content – so much so that I often find them too sweet.  I think Mark just grew the Indian corn out of curiosity the first time. This year he put in a bigger row of it because we used all the previous crop and he is looking for grain crops that we can grow, harvest and use here.

I only have a photo of dead pheasant. We found two which had been hit on the road but he counted more than that in the patch.

He was loving the presence of the growing population of beautiful pheasants in his cropping area across the road until he realised they had quietly consumed about a third of the Indian corn. We are still delighted to have a local population of exotic-looking pheasants but he hastily harvested the remaining cobs.

Curiously, when I dehusk the dried cobs, the remaining core also shows colour variation. Red kernels usually mean a red or purple cob.

Kernels, maize flour and the handy old coffee grinder I kept in case it was needed again one day

What do we do with the corn? Home made corn crackers! I first tried grinding the kernels in the food processor and it had to work hard to achieve a fairly coarse result. I worried the meal may crack tooth fillings. Then I remembered the old electric coffee grinder I put away in a top cupboard when we upgraded to a burr grinder for coffee beans. It does an excellent job. The texture is not completely consistent and I don’t think I can manage the process to get polenta meal out of it, but it is fine for crackers. I have stopped buying corn chips and taco shells. My thin crackers make a more than acceptable substitute, though I would be lying if I said they tasted the same. I have learned that the kernels need grinding immediately before they are used because the flour goes mouldy really quickly.

I doubt that many readers have a crop of maize or Indian corn sitting around waiting to be used, but just in case, I offer you my recipe which I adapted from a great recipe I was given for making seedy crackers.

About 1 ¾ cups of fresh ground maize flour

¾ cup of spelt flour

2 tbsp chia seeds

1 tsp salt

1/3 cup olive oil

½ cup water

Mix and then roll out thinly on baking paper with another sheet of paper on top. Sprinkle the top with coarse salt flakes and grated parmesan cheese or similar (I used grana padano because that was what I had) and cut the sheet of cracker into suitable sized squares but leave it as a sheet.

Bake in a medium low oven (about 130 on fanbake) until it is golden brown and crisp (about 30 mins but keep an eye on it).

That is it. From grinding the corn to getting crispy, tasty crackers out of the oven takes about 40 minutes. We ate them this evening with chilli beans (homegrown, of course) and will continue to eat them during the week as a snack, with or without toppings.

Rolled and ready for baking

Started at last – a perennial meadow

Not a blank canvas – closer to a wasteland with potential

Sometimes a garden can catch you unawares. At least, that is the case in a large garden. It is probably harder to avert your eyes from messy areas in a small garden. So it was that I found myself in the Iolanthe garden this week, thinning both the Daphne bholua forest that had formed (there is a plant that can seed and sucker alarmingly if you turn your back on it) and the sugar cane patch.

The original plant of Iolanthe is the dominant feature on one side 

Iolanthe has only opened her first two blooms this year but here is a view I prepared earlier

I paced out the Iolanthe garden and it is somewhere over 500 square metres so it is not a small space, though it is in a prime position and has a mix of shade and sun. It lost its way some years ago. In Mark’s father’s time, it was his vegetable garden but as the original plant of Iolanthe grew ever larger, the shade increased. I admit to having done a major effort on it back in the early 1990s, attempting to turn it into a stylish potager. In self defence, it was the fashion at the time and I was following Rosemary Verey’s example. I divided the space into rectangular areas defined by square, concrete pavers and planted rather a lot of twee buxus hedges. Of course, anybody with experience can tell you that little buxus hedges are not actually compatible with growing plants like vegetables that require friable soils to be dug over every season. Their root systems encroach ever more on the surrounding areas.

At its best, Mark’s chaotic butterfy garden could look like this – but all too briefly

Mark’s dad was patient with my efforts to pretty up the area but Mark removed most of the buxus in the years that followed. He then relocated the vegetables to a sunnier area on the property and the Iolanthe garden became the holding area for plants that needed to be relocated to other parts of the garden ‘in due course’ and the trial area for growing perennials he was buying in to see how they would perform here. And it became increasingly chaotic. At its best, in summer, it was Mark’s butterfly and bee garden with a riot of unrelated flowers, both self-seeding and planted. At its worst, it was a mess and that was for most of the year. I could no longer ignore it and it needed more than just an annual spruce-up.

This is a massive job and I had already started when I realised what I was doing – making a perennial meadow. We have made a considerable study of meadows and I have written plenty about different meadow styles. In our climate and conditions, we have to maintain some level of weed control at all times so that pretty mix of flowering annuals and field grasses is not a look we can maintain. But finally, I think the threads are coming together and I can plant a perennial meadow that will require only light maintenance and flower for maybe nine months of the year. The influence is very much Nigel Dunnett and some of the plantings I see on Pictorial Meadows. If you want to know more about this, google the work Dunnett has been doing at Trentham Gardens, near Stoke-on-Trent.

Existing citrus trees in this area

We are extending the permanent trees and shrubs. Mark has long talked about establishing an orange grove to give some purpose to the area. There are already about 10 citrus trees there (tangelo, limes, lemon, oranges and mandarins) and another three plants were hanging around the old nursery waiting to be planted. And feijoas. There was one growing and another two waiting for a home. Same with the tea camellia (C. sinensis).  While we are never going to be self sufficient in tea, I have taken to harvesting the big plant each spring and Mark had another two or three waiting to be planted.

Planting beneath the widely-spaced trees and shrubs is the big task but also the most interesting one. The meadow effect. Liberated from the feeling that I must manage the colours carefully and follow certain rules for herbaceous planting, all I am doing is thinking as I go about sustainable combinations planted in loose blocks. I am using the plant material we have to hand but avoiding using the perennials I have already featured heavily in the sunny perennial plantings around the new Court Garden area. In other words, really casual plantings but strong growers, a different plant palette so it doesn’t all look the same. Am I lucky that we can go into planting a fairly large area drawing on plant material we already have around the place or is that good management? Using material we already have does mean we know how it will perform in our conditions and how to manage it.

It was a throwaway comment from Mark that made me think more clearly about what I was doing. “I’ve always thought wind anemones have a place in an orchard,” he said. Yes! I thought. We have two shades of pink Japanese anemones on our roadside that I can raid and this is a place where they can grow in their own space and star in their season.

Elsewhere, we have a variegated agapanthus that I have never found the right place to feature in the garden. I have yellow day lilies I could use with that in one block. It is painting with plants and that is fun. I have already interplanted the purple eucomis with yellow crocosmia and am now interplanting bluebells and a pink alstromeria.

I have more confidence with this venture having ascertained that a small area I replanted two years ago and mulched heavily with fresh bark and leaf chip has stayed weed free. This week, I found that the price of a truckload of up to 6 cubic metres of such mulch material can be delivered here for a mere $100. This seems like a bargain to me. I am waiting for my first load and will mulch heavily. As with everything we do in the garden here, we factor in sustainability and maintenance from the very start.

Our bulb hillside plantings are successful but do not a meadow make

We have always wanted a meadow and have had success with bulb hillsides but have been apprehensive about going full-on into a more extensive area. There is romance in the simplicity of flowery meadows but that does not mean they are simple to create. I am hoping that we now have sufficient experience and knowledge to make it work. It may be the last piece in the assemblage of sunny perennial gardens we have been putting in – all different in style and concept with very little overlap in the plant selection for each area.

I have a lot of work to do before summer to get the meadow planted. I just wish it wasn’t quite so muddy at the moment and that the weather gods would give us a spell of several dry days in a row.

It is an old photo but one of my favourites and is the view at one end of what is to be a perennial meadow
