A dead tree, an alive Australian plant and too much miscanthus

4 Replies
The grey coloured tangle of branches was the dead malus

We had our preferred arborist back this week. The dead malus in the entrance was not huge and access was easy but it looked like one of those jobs that would take us at least a couple of days but that he could complete by morning tea time. I was pretty much right on that. By 10.30, it was down, firewood cut to easy sizes and small stuff all fed through the mulcher.

A mere three hours later. Sometimes getting in the professionals is worth it.

The arborist described it as being like a bird’s nest. It was an extraordinary tangle of fine branches. I wondered how much of a gap it would leave but, in the event, not much, really. The prunus that stood beside it is looking more glorious in its autumn raiment.  It sent me down a rabbit hole, looking for earlier photographs of the area.

The entranceway back in 1986

Oh look. Here we have it looking remarkably romantic in April 1986. It was still being grazed by sheep and Felix still had his hens. And, looking carefully, it appears that the cherry trees and likely the crabapple were planted around this time so that particular tree lasted for close to 40 years.

The three diagonals heading upwards to the left are flower spikes
Same clump flowering in 2018. It has grown.

The Doryanthes palmeri has put up three flower spikes! I use the exclamation mark because this particular plant, commonly known as the Queensland spear lily, has only flowered once for us, back in 2018.  It was pretty remarkable, with the flowering lasting a good five months. In the years since, the clump has grown substantially and the entire Court Garden area has been developed and planted. Like the cardiocrinum lily, each rosette only flowers once after many years but it then sets offshoots which will also take many years but then flower spectacularly. They are surely the sturdiest flower stem of any plant we grow but not for the faint-hearted or small gardens. Our clump is now around five metres across.

Zach and I have been reviewing the adjacent Court Garden. It is time for some significant thinning and a major cull on the Miscanthus ‘Morning Light’. I see I wrote three years ago: 

What amazes me is that this plethora of Miscanthus ‘Morning Light’ all descend from just one small plant that Mark bought originally. It was still just one plant, albeit a large clump, when I first lifted it and started dividing it in 2017. We have just kept dividing since. In those six intervening years, that one original plant has now yielded several hundred sizeable clumps.

The miscanthus is falling apart after just three years – a sign that it needs more attention than we are willing to give it on an ongoing basis

Just three years ago, every miscanthus in that garden was dug out and carted away (to Pukeiti Gardens, no less). Zach had smaller clumps ready to go straight back in, divided from one of the plants. Three years on, they need lifting and dividing again. Already. This is not light work, the clumps are huge and falling apart.

At its best, shining in the lower angle of the winter sun
Too demanding of attention – this plant will collapse apart with rain.

It is a good looking and obligingly easy grass. As far as I am concerned, its best season is around the winter solstice when the sun comes in at its lowest angle, lighting up the pale flowerheads like moving lanterns. That is a magical sight. But we don’t need 25 to 30  clumps of it in the Court Garden to shine like lanterns in low winter light, all needing lifting and dividing every three years.   I think we can make do with a third of that number. It is not worth the effort required to keep it looking good in larger numbers.

Our native red tussock – Chionochloa rubra – is just a fantastic plant, given room to festoon

It might be time for me to update The Grass Report. The brief conclusion will be that if you have the space – at least two metres across in all directions – the low maintenance, looks-good-all-year-round, shining star of the grassy garden here is our native red tussock – Chionochloa rubra. I wouldn’t be without it.

April bulbs in bloom

Plenty of cyclamen flowering in shades of pink and pure white

Unlike earlier months, the April bulbs here have been a narrow range of different varieties, although certainly not in terms of numbers. The rockery in particular is a carpet of Cyclamen hederifolium but, as that became full, we have gently encouraged its spread to anywhere it wants to grow. It is very much the easiest and most adaptable of the cyclamen we grow.

Nerines and Moraea polystachya together

I wrote about both the Nerine sarniensis and the Moraea poystachya last month as they hit their peak. Both are heading towards the end of their season now but a six week season is a long time for a bulb.

The autumn snowdrops are always a surprise but at last I looked them up and I am pretty sure that these are Galanthus reginae-olgae, Queen Olga’s snowdrop. In the likelihood that few readers, if any, even know who this Olga was, I can advise that she was Olga Constantinovna of Russia who was also Queen of Greece at the time when a Greek botanist identified this species native to the area.

Now to commit the name Galanthus reginae-olgae to memory….

Mark often cites this snowdrop as an example of how even the most charming of bulbs is most charming when it flowers in the season when we expect it. Snowdrops, he feels, belong in late winter to earliest spring – harbingers of season change – and most of them do flower then and we are delighted to see them. It is why, as a plant breeder, he wants plants to flower at their allotted time of the year, not to appear as a novelty at the ‘wrong’ time.

I digress, but when a new species of camellia, known first as C. changii but then renamed to the less helpful but correct in plant nomenclature C. azalea, became available, his interest in acquiring it for breeding was decidedly lacklustre. Its main flowering is in summer whereas pretty much every other camellia flowers in autumn (for sasanquas and some species), winter or early spring. A summer flowering camellia still strikes him as fundamentally on the fringes of the natural order; after all, he argues, we have an abundance of other summer flowering plants and we don’t need a range of camellias flowering at the same time.

Schizostylis oo hesperantha. Or river lily, apparently.

A somewhat unsung but easy autumn rhizome is what we know of as a schizostylis but I see it is more correctly named as Hesperantha coccinea. I am not sure which name is easier to remember but maybe its common name of ‘river lily’ could be helpful, even though it is an iris, native to southern Africa and Zimbabwe. I see photographs on line of it growing in big clumps, but its foliage is unremarkable. I divide it up and dot it through the cottage gardens we refer to as the Iolanthe garden to add an extra bit of autumn colour and interest. It seems to be more favoured in the UK where it has a history in the cut flower industry and various named cultivars selected and even awarded by the RHS. Perhaps we are not so much into autumn bulbs in these southerly climes.

I made the mistake of planting O. eckloniana in a rockery pocket and have been weeding it out ever since. It is mighty handsome in a pot, though.

The other main group of bulbs just hitting their stride are the ornamental oxalis. Set aside your prejudices about oxalis – there are a few that are real pests and downright weeds but there are also some that are extremely ornamental – pretty as. But they are not all equal. Some have good looks but a fleeting season in bloom (here’s looking at you O. fabaefolia and flavas pink and white). Some are downright dangerous with thousands of teeny tiny bulbs that if you liberate in your garden, you will never get rid of unless you replace the soil entirely. Some are not strong enough to survive well in garden conditions and need to be nursed along in pots. But some are excellent in the garden and not a problem at all.

Oxalis purpurea alba. We find the pink flowered forms of this species invasive but this lovely white form is reasonably strong growing but not weedy and it is easy to remove entirely if required.
I would give the same verdict on O. luteola – long flowering season and garden friendly.

When our Zach was doing his apprenticeship here, he was required to curate a collection of plants and he chose oxalis. He has a collection of over 30 ornamental species now, most retrieved from the garden where I had planted them (and regretted some). They are variable in terms of garden merit but it is hard to beat O. purpurea alba and O. luteola as garden plants. Call them by their common name of wood sorrel if it makes you feel better.

Just a small sampling of the more than 30 varieties we have in the oxalis collection. There is a wide range of leaf type, flower size and colour.

And so to May this coming Friday. The new month will open with Nerine bowdenii, the last of the nerines to flower for us each season and the easiest to grow and bloom. I see its first flower has opened.

A postscript – or maybe an update –  to my last two posts on digging ‘n dividing and bluebells.

I photographed this patch of asters trimmed to the ground because I thought it was a good example of when not to let sleeping asters lie. Digital photography is very handy for dating things and I see it is only three years since these were last dug and divided. It had become a seamless carpet of aster in the time since. Both Zach and I noted that it did not look as good as it should have last summer. They weren’t helped by getting hit by mildew which has not happened before, but there was no mass flowering.

It should have looked like this last summer, but it didn’t. This is from summer 2024.

Time for a dig and divide, which Zach did this week. A perennial that has to be lifted and split every two to three years is on the high maintenance side and we don’t have many in that category. My friend, Sue, who leads the team of volunteers at the pretty Te Henui cemetery, told me she is culling plants that are too high in maintenance for their labour resources and this aster might fit that category. I must ask her for her latest list of culls. Fortunately I have Zach to carry out such tasks or I might be casting around for a less demanding plant option.

Enter the rabbits. After a quiet few months on the rabbit front, they are back and there is nothing they like more than an area of soft, freshly dug garden and mulch to dig. I sent Zach a text yesterday telling him that the rabbits were undoing his work. He was equally unimpressed but at least the photo shows you the size of division he split off from the previous carpet to replant.

I have just replanted the casualties, filled in the holes and spread blood and bone. The rabbits don’t like blood and bone and will stay away from that area but it does need to be replenished after rain and we have had plenty of that this week.

A whole lot of bluebell bulbs, just from the Iolanthe garden. There were more. I have already disposed of some.

The war on bluebells continues and I am at an advanced stage of boredom. I took this photograph as proof that I am not exaggerating. This is by no means all of the bulbs I have dug out of just the Iolanthe garden. Most were never planted there but I will have spread a few when I planted that area in 2019. Some have already been disposed of and still there are more to be dug.

They did not dehydrate in the summer sun. They grew instead.

Bluebells have no place in the cultivated garden. I found a couple of photos from last year, recording our attempts to deal with some culled from the Avenue Gardens. I worried about how many we were dumping on our wild margins and they don’t rot down in the compost. I had the idea that if we spread them thinly on weedmat, they would dehydrate and die in the summer sun. They didn’t. They kept growing. I then thought they might compost in plastic bags in the sun, as wandering tradescantia does. Some did over the summer months but others in those bags were still firm and viable. Responsible disposal is quite a big problem.

Nor did they rot down in the plastic bags, as I hoped.

We have a lot of bluebells in the park and the Wild North Garden and they can stay there. To get rid of them, we would have to go for repeated use of some heavy-duty sprays and we try and avoid that. Besides, they are very pretty in spring. Ours are all Spanish bluebells or hybrids; the more desirable English bluebells are extremely scarce in this country. I don’t think I have ever seen them.

“If they stank like onion weed, they would be seen as a weed,” said Mark. “They are a weed,” I replied.

If we had our time over again, we would think twice about introducing them to our property. Mark put a bit of work into building up numbers in the first place. A decade or so on, I am putting a great deal more work into digging them out from some areas, all but sifting the soil to get the baby bulbs. You have been warned.

From happier bluebell days

Let there be flowers and the gentle change of seasons

In a world that seems to be growing more chaotic, unstable, downright dangerous and even vicious by the day, let there be flowers.

I know I am not alone in limiting my time following the news and on social media. Never in my life did I think I would be taking life guidance from RuPaul but his advice to ‘look at the darkness but don’t stare’ are words that I repeat to myself every day. It is one thing to be aware of what is happening but it can be overwhelming if I spend too much time following it closely.

The bright cheer of the dwarf helianthus makes me smile. This is a named cultivar but I have forgotten where I recorded the name.

Instead, I give you the gentle predictability of the change of season from summer to autumn here with photos from yesterday. I have used the shorter version of the helianthus in the borders but the tall leggy form – likely closer to the species or as it is found in the wild – seemed to fit better in the controlled abandon of the Court Garden. No more. We are in danger of losing it because it is not as capable of coping with competition as I thought. As soon as this remaining clump has finished flowering, I will relocate it to the more cultivated environment of the borders where it will be given its own space to thrive.

The Jerusalem artichoke is also a member of the helianthus family but it does not justify its place as an ornamental plant. Not enough flowers, I am afraid, but an abundance of tubers which I dare not eat. While tasty, no matter how hard I try, I can not find ways to prepare it that improve its digestibility without the unfortunate side effects. Its name as fartichoke is fully justified.

The heleniums are in the twilight of their season but remain eyecatching. These have one of the longer flowering seasons of the summer perennials and fully justify their prime position in the borders.

Cyclamen hederafolium are coming into their autumn peak and what a delight they are. We have many of them, many many in fact because we encourage them to seed down in their pretty pink and white charm. I am not a fan of the bigger cyclamen hybrids but the species are a source of great delight throughout the garden.

The rockery is hitting its stride with its autumn display. The colchicums are a fleeting delight but one we would not be without. The nerines are just starting, mostly red so far but plenty about to open in other colours. I live in hope that the Lycoris aurea will stage a reappearance. I planted a pot of flowering bulbs out in the rockery years ago but I can’t remember where and it has never flowered since. It may have gently withered away to nothing or it may still be masquerading as a random clump of nerines which I just haven’t noticed aren’t flowering. Perhaps our hot, dry summer will have triggered it to flower. Or maybe not.

We have two dwarf crabapples in the rockery, standing little more than 1.2metres high after about 50 years. Their flowering is insignificant and their form and foliage unremarkable but they justify their place with their ornamental fruit in autumn.

Moraea polystachya, an autumn form of the peacock iris, seeds around enthusiastically but harmlessly and rewards us by popping up randomly – on the edge of the drive in this photo – and having one of the longest seasons in flower of any of the autumn bulbs because it keeps opening a generous succession of buds.

The belladonnas are bold, a bit scruffy and have bulbs and foliage that are too large to make them obliging garden plants. But they are a welcome addition in wilder areas, in this case on the site of the old woodshed we removed this summer before it fell over of its own own accord. We don’t know anything about the grinding wheels except that Felix must have gathered them up fifty years ago and there are three in graduated sizes.

The first cymdidium orchid is opening. This somewhat understated one is always the first of the season and is a top performer in its spot, arching over the old stone millwheel which has been repurposed a bird bath.

Finally, camellia season has started. Camellia sasanqua ‘Crimson King’ is always one of the first to open. Even with climate change, there is a reassuring predictability in the cyclic nature of the seasons.

May there always be flowers. I can stare at them as long as I like without fear of being overwhelmed by a sense of despair, anxiety and helplessness. In the flowers and the seasons lie promise and joy and we need a whole lot more of that at this time.

STILL pruning…

It is an experience shared by most gardeners. I will just get this (smallish) job done and then go on to something else. And that smallish job expands from a few hours to days or even weeks. So it is with trimming camellias, about which I wrote last week. I am still doing it.

A rare sight these days – good flowers on Jury’s Pearl.

We don’t trim a lot of camellias, I thought to myself. And then I added them up. Excluding the camellia hedges – and there is a fair distance of those – I reached about 40 that get individual attention every year. That is not a lot compared to the number of camellias we have which must be several hundred, but it is still quite time consuming. Some we trim to be feature plants; some we trim to freeze them in size.

A relatively dry winter has meant we have had a better show this year. It doesn’t resemble the mass displays we used to get before the devastation wrought by camellia petal blight but there have been some pretty blooms. Most of our larger flowered camellias are retained as shelter, screening, wind breaks or their attractive form, certainly not for floral display because that is but a memory and the larger flowered types get hammered by petal blight. It means more work to ensure that in key spots in the garden, we have to make that attractive green form visually effective in order to justify keeping them. We have a strong preference for the small flowered varieties which do still put on a good show. And autumn flowering sasanquas, of course but they are long finished.

Fairy Wand has been reduced to a skeleton and we may drop it lower yet. We try and keep a good framework when we are cutting camellias very hard, not cutting off at ground level.
That is A LOT of Fairy Wand piled up to be mulched

Camellia ‘Fairy Wand’ started life as a miniature back in the days when miniature only applied to the flower size and not, as most people assumed, growth habit. Bred by Os Blumhardt in Whangarei, Mark planted it, ‘Gay Baby’ and ‘Tiny Star’, also from the same breeder, beside our driveway. After about 40 years, they were all about six metres tall and in a decidedly leggy state, with wayward branches being cut off to keep the driveway clear. We stagger our extreme pruning here. ‘Tiny Star’ was cut back two years and is now a bushy little column shape about two metres tall. This week was ‘Fairy Wand’s’ turn for drastic treatment. ‘Gay Baby’ will be done at some stage in the next two years, when ‘Fairy Wand’ has rejuvenated. We don’t want a row of three massacred plants. It took Zach all of an hour to cut back the Fairy and about the same length of time for Lloyd to mulch it up for wood chip.

Taking Fairy Wand down behind gives this tableau of clipped camellias a whole lot more impact, especially the cloud-pruned sasanqua Elfin Rose. We are now thinking of dropping Fairy Wand behind even lower so it stays below the cloud pruning.

As an aside, it is possible to rejuvenate most michelias in the same manner. You do need to start with plants that are growing strongly because if they aren’t, the shock may kill them but we have, upon occasion, cut michelias as ruthlessly to promote bushy fresh growth.

Itty Bit in the centre after being reduced in size by about 40%

While Zach may only have taken an hour on ‘Fairy Wand’, I have spent many hours on others and that is because we want the form and shape on a healthy plant. I probably removed about 40% of ‘Itty Bit’ to reach this stage.

Camellia Hakuhan-kujaku – a shadow of its former self

It took me ages to get ‘Hakuhan-kujaku’, the peacock camellia, to this state. I took out at least 60% of it and it looks a whole lot better for the time spent. Shapely, not hacked or massacred.

Camellia minutiflora front right, Itty Bit behind

Little C. minutiflora is one of my absolute favourites, though hard to get photographs that do it justice so you will just have to take my word that it is a little charmer. It is a more recent planting so I probably only took 25% off it. At least it will only be a tidy-up trim for the next few years until there is so much congested growth and crossed branches that it is time to spend hours laboriously picking over every branch again.

My secateurs and pruning saw are my best friends at the moment. If you are wondering where to start on this type of pruning, I start by looking at the plant from every angle. Because we are trying to keep the plants from getting tall and leggy, I first take out growths on top that are going straight up instead of bushing out sideways. Then I work around the perimeter, reducing the spread, always trimming growth flush to the branch or trunk. Then I get into the middle and take out crossing branches. Finally, I get underneath and trim from below, making sure there is cover across the top while taking out surplus growths and branches below. I spend a lot of time looking and tracing where main branches go. This is why it takes time.

Look! Just look at this exquisite little chaffinch nest lined in soft feathers. Must the chaffinches start all over again because we humans destroyed their nest? Disclaimer – this one was blown down in a storm.

At this time of the year, I remember the warning from friend and colleague, Glyn Church. Pruning needs to be finished very soon on taller trees and shrubs. The birds are nest building and will be laying eggs. Unless you are okay with destroying days of hard work by individual birds and killing off their young, time is of the essence.

They are just common, pesky blackbirds but it still does not feel right to kill them for human convenience or by human carelessness.
A tui nest.
