When good plants go rogue

I liked how the cutwork foliage provided a contrast to the dominant grassy foliage

It is no good. The plume poppy had to go from the sunny Court Garden. While I liked the foliage contrast, it is just waaaay too invasive to leave in place.

That is the full extent of the flowers. Pinky beige, perhaps?

The plume poppy is Macleaya cordata, native to China and Japan. It has an attractive blue-grey leaf that looks a bit like the plant version of cut-work embroidery. In spring and summer it shoots up stems to maybe two metres before flowering. True, the flowers are not exciting. More brown than gold, they look like seed heads even when they are in full bloom but they have a certain feathery charm while playing second fiddle to the more striking foliage. The problem is that it runs below ground, more like sprinting than running in some situations.

Here a fortnight ago, gone today on the grounds of bad behaviour

We have grown it for years in the high shade of the Avenue Gardens where it has not been problematic. The running tendency slows in shade – more a walking pace  – and in the thinner, dry soils it is easy to pull out wayward shoots and keep it to an area. I was not prepared for what it would do in cultivated soils in full sun. Not only did the runners bed down to a greater depth but they headed off with gusto in every direction, popping up metres away from the original plant.

Making a break for it

Really, it was the determination to colonise the paths that sealed the fate of this plant. Look at these runners appearing in the terrace. Not only have the shoots struck out enthusiastically on every side, this terrace is 30 cm higher than the garden bed, separated by a brick wall. I just don’t need a plant that can make such determined efforts to colonise. It was already growing through other perennials in the garden beds and leaping beyond.

It is going to take me a few years to completely eradicate it because roots that remain below ground will continue to push up growing shoots but I removed all that was visible two weeks ago and will just keep on its case until it finally disappears.

Macleaya cordata can remain quietly co-existing in the high shade of the Avenue Gardens

It can stay in the shade of the Avenue Gardens but I can’t be having invasive thugs in the Summer Gardens.

Phlomis russeliana flowering now in the shady Avenue Gardens where it will probably be fine left to its own devices for another decade or so.

Another plant that has surprised me with its vigour is Phlomis russeliana or Jersualem sage. While described as a perennial for sunny spots, we have long used it as a low maintenance, obliging bedding plant in the high shade of the Avenue Gardens. It has never needed any attention there, bar cutting the tall growth and spent seed heads back to the ground at some stage in winter. The only time I have ever done any work on lifting and dividing it was when I raided the patch to get plants for the new, herbaceous borders.

In the sunshine, the phlomis romps away and needs major attention every two years at least.

Introduced to the bright light of full sun and well-cultivated soils, the phlomis has become something of a triffid. The growth is lusher and much stronger. The twin borders are only entering their fifth summer but the blocks of phlomis have already been lifted and divided twice, discarding probably half of them in the process. I think I can get away with a total dig, divide and replant every second year if I alternate it with picking and thinning them from the top in the year between. It is a bit more work than I had anticipated for a cheerful but utility plant.  While it seeds a bit more in sunny conditions, at least it doesn’t spread below ground like the plume poppy.

The lines between a strong grower, a thug and an invasive weed are sometimes finer than we expect. Generally, we will cope with the first and get rid of those in the second two classes.

The exotica of water lilies

If I believed in woo-woo (or, at least, that plants can sense what humans are saying), I might think that the appearance of this charming, little lemon water lily flower was because of my threats made over the past few months. The plant came into our possession about ten years ago and it has lived in a vintage pot ever since without flowering. Maybe three years ago, I took it out, reduced some bulk, raised it higher in the pot and gave it some new compost mix. Nothing happened. It just put up its usual leaves. I declared this year – probably in its hearing – that this was its last year. If it didn’t flower, I would cast it out and find something more obliging to grow instead.

And lo, this flower appeared and it has won a reprieve. It is a very pretty little flower. Water lilies do have lovely blooms with a pristine purity of form.

The vintage water pump is, I admit, merely ornamental in this situation.

We have water lilies in assorted bodies of water. The purest white one in a round pond on the side law is the best, I think. A white waterlily is the national flower of Bangladesh but looking at the photos, while similar, I think it is a more tropical form than this one.

The setting
The one in the goldfish pond at the bottom of the sunken garden is a bit murky in colour

I don’t find them the world’s most exciting bloom but they have an exotic beauty to them. I looked them up to see where their homelands are and I see they are broadly spread across the globe ‘in temperate and tropical climates’ which is pretty sweeping. They are a bit more complex than I expected though, if I am honest, I would admit I have not given them a lot of thought. Their plant family is Nymphaeaceae and I will never remember how to spell that with all it’s ‘a’s and ‘e’s. There are about 5 genera in that family and maybe 70 different species which don’t all look the same as the ones we grow. That is quite a lot of different species. As far as I can see, the ones we see here are from the nymphaea group.

The bigger growing forms we have in ponds in the Wild North Garden are lovely but they need occasional intervention to reduce their spread or we would have no visible water remaining

Water lilies grow from rhizomes rooted in soil so they only grow in fairly shallow water. Many years ago, we went to visit two ‘water gardens’. In fact, they were water lily gardens. I can’t recall other aquatic plants. That is where I learned that some varieties can be such strong growers that they will entirely cover the water surface if they are not restricted. A mass of water lilies without visible water reflecting, shimmering and rippling to frame the plant is not actually that aesthetically pleasing or exciting to see.

The loveliest water lilies I have seen were in the Xishuangbanna botanical gardens in southern China. They were held up above the water on longer stems and I think this makes them a different genera to the common nymphaea types we grow here. “They’re tropical,” Mark said, but he may have been generalising from the fact that it was hot and many of the plants we were looking at there were very tropical. I have no idea if that type is even in NZ.

This week at least, I am happy that the pretty lemon one has flowered after a very long wait.

A lucky escape

There was a clue from the back doorsteps but neither of us noticed it immediately

Mark is an under-stated man who never gets carried away by the drama of a situation. As we sat down for our early evening conversation before dinner yesterday (a glass of wine may have been involved), he let me tell him about something that had distracted me during the afternoon before starting to tell his news. “I was wondering,” he said, “when I planted rimu trees to take over from the old pines, why I placed one so close to one of the younger pines which had good foliage.”

I didn’t even realise he had done this long-term sequential planning for replacement trees under the old pines. Some of these trees are now coming up to 150 years old. When he referred to a ‘newer’ one, he was referring to those planted by his very late Uncle Les when he still lived with his parents here, rather than those planted by his great grandfather – so ‘newer, younger’ in this context means maybe 100 years old.

Then came the kicker comment: “It seems I didn’t have to worry about that.” I have lived with Mark long enough to know what he meant – the pine tree had come down. This would not have been anything more than inconvenience and a big clean-up job were it not for the timing. When we had a tearing gale during the garden festival ten days ago, we closed off the Avenue Gardens as a safety measure and changed the route for visitors to walk up the very path the tree has fallen across and blocked entirely.

We closed off this path as being too risky during the gale force winds ten days ago …
… and redirected to this route
Now it looks like this. At least it didn’t happen during the recent garden festival

The mystery to us is when it fell because neither of us heard it. I walked up that path mid afternoon on Friday. Mark found the fallen tree late afternoon on Saturday. So there is a 25 hour time frame and in that period, there was rain but no wind. There would have been a loud crack, the sound of breaking branches and then a loud whoomp when it hit the ground. But we heard and felt nothing. Mark thinks it must have happened at night when we were both in deep sleep but I am sure we would have woken because it is not that far from the house. I think it must have happened when I was out shopping on Saturday morning and Mark was working in the shed with the radio on. He is adamant he would have heard it and felt the vibration. Maybe it thought nobody was here to hear it so it did not make a sound? (*Philosophy joke.)

Ah well. A whole lot of firewood has arrived, more than enough for us so we will be sharing it. And we have learned yet another lesson about the unpredictability of when and which way trees may fall when they come down.

It looks smaller in the photograph than it does in real life. I had neither person nor dog to pose for scale. It is about 100 years old.

Rhododendron season

My favourite rhododendron – R. sino nuttallii

Occasionally, Mark and I torture ourselves remembering our years retailing plants. Do not get me wrong. The nursery served us well and enabled us to put our children through university and to retire early. We met many lovely people and to this day, former customers will tell us what they bought from us. Sadly, it is the obnoxious ones that stick most clearly in our memories. There can’t have been that many of them because, between us, we can come up with individual details and sometimes even names. I doubt that any read my posts.

One of Felix’s yakushimanum crosses – this type of rhododendron does not spark joy for me, personally speaking.

Mark built the nursery on rhododendrons in the first years and indeed, the garden here was primarily seen as a rhododendron garden. They were a hot ticket item and well over 100 000 were produced in Taranaki alone every year. Quite early on, Mark analysed the fact that many of our mailorder customers came from the upper half of the North Island and decided that if he was going to sell them rhododendrons, he would pick the varieties most likely to perform well in warmer climes. Most of the big, showy American hybrids that were flooding into NZ at the time – the likes of ‘Puget Sound’, ‘Lems Cameo’, ‘Anna Rose Whitney’ and so many more – needed colder winters and less humid summers than we can provide. We have lost many of those American and European hybrids in the garden here now and I am sure they never did well in Auckland.

He targeted a range within the maddenii group which were usually characterised by looser trusses of bell-shaped flowers, fragrance, mostly paler colours and, most importantly, healthy foliage in warmer climates. Many were from his father, Felix’s breeding efforts and Mark added to them.

‘Moon Orchid’ – a sister seedling to Barbara above

This week when the R. sino nuttalliis are looking so glorious they can take my breath away and many of the maddeni hybrids are flowering, I thought back to those retailing days. It was a constant uphill battle to convince customers that these were splendid plants much better suited to their conditions when their mental image was entirely focused on the classic rhododendron look of big ball trusses sitting atop the foliage. In the 1990s, if they were male customers, they not only had to be big ball trusses, they had to be RED. It became a joke here that every time a nursery plant opened a big truss of red flowers, a man would buy it on the spot. If women bought a red rhododendron, it was almost always for their husband.  Maybe times have changed in the decades since.

One of the loderis – we think it is ‘Venus’. It is a bit of a ratty plant all year except when in bloom when it is glorious

A rhododendron friend who went around the garden last week commented on how lovely it was to see mature rhododendrons in a garden setting. I had forgotten that huge gulf between tidy, little nursery plants standing maybe 50cm high in their pot and the large specimens we have in the garden. I don’t miss those days of nursery production and sales one bit.

Just a random row in the trial area
Look at how clean the foliage is, given the total absence of any attention and very open conditions

Ironically, as rhododendrons fell from favour in the market, Mark started to get the breakthrough of big, ball trusses on plants that kept good foliage (not turning silver from thrips and getting crispy brown edges to the leaves). We have a long row of them quietly growing in full sun and open conditions in the trial grounds. They are not my favourite; big ball trusses are less appealing to me and they have no scent. Mark is a bit underwhelmed by the flower colours – he doesn’t see any colour breakthroughs in them. But what sets them apart is that growing over the years with no care, no spraying, no fertiliser, no pruning and in full sun, many of them have kept excellent, clean foliage and they cover themselves in blooms every year. That is the breeding step that he managed.

More seedlings but it is the foliage we are admiring

They were bred specifically for our conditions but the commercial market for rhododendrons in NZ is so small now that there is no incentive at all to release them. He just reached that breeding goal too late for our nursery days and for when rhododendrons were an elite and fashionable line. Such is the life of a plant breeder. They can just sit over in the trial grounds. We have the space and they are not doing any harm there.

Is there anything lovelier than a sino nuttallii?

I have long said that if I could only grow one rhododendron, it would be a R. sino nuttallii. I doubt that they are available commercially here these days when specialist growers have all but gone, although some of the nuttallii or madennii hybrids are still around. Most of you will just have to enjoy them vicariously and take my word for their bold beauty and delightful fragrance.

2021 Taranaki Garden Festival in Covid Times

White ixias and Iris sibirica ‘Blue Moon’ in the summer borders

As you read this, we will be on the last day of the 2021 Taranaki Garden Festival. Ten days may not sound long but it is very long when you are meeting and greeting visitors solidly, especially given our lives where we spend long periods of time alone with our own thoughts in the garden. So forgive me if I seem a little tired.

It has been an odd festival. Last year broke all visitor records when the country was Covid-free but nobody could travel overseas. This year was shaping up to be even larger until Delta took hold in Auckland and then Waikato. With internal borders closed to the north of us, we kept our fingers crossed that they would reopen in time for the festival but it became clear that would not be the case. When we had ten coaches cancel in the week before festival, it was a bit… deflating, shall I say? With those northern borders closed, we could see that 40% of the visitor base simply couldn’t travel. Added to that, a fair number of people to the south didn’t want to travel and who can blame them? Preparing the garden for a festival that seemed to be dwindling day by day felt very much like being all dressed up for a party but nobody was coming.

In the end, it has been fine. Yes, visitor numbers are way down on the early indications but overall, we have still been running above our long-term average. Not hugely above but better than expected.

Our friend and helper on the gate during a Covid festival

A Covid festival has been different to manage, especially in this country where we were late to adopt wearing masks. But I can report that the particularly loud – rabid, even – but small number of Covid deniers/anti maskers/anti vaxxers are not garden lovers. We have had 100% cooperation on scanning or signing in and keeping to our masking policy (mask at the entrance and then carry it around the garden to wear if near others). None of us likes masking but nobody wants to spread Covid in areas of this country that are still blessed to be free or largely free from it at this stage*.  The good-natured compliance has been a surprise to us but very welcome. It seems that when expectations are clear, people respect the protocols. I have found managing physical distancing challenging when taking workshops and leading tours around the garden but goodwill goes a long way.

Even we never work beneath these trees in windy times; we were not going to risk visitors’ safety.
Blocking off paths and redirecting visitors around danger areas

Wednesday – oh windy Wednesday. It is a long time since we have experienced a wind such as the one that blew relentlessly all night and day. It was not so much wind as a howling gale. At least we managed to remain open and areas of the garden are so sheltered that all that could be heard was the roaring in the treetops above. A few other gardens were forced to close entirely. For the first time, we closed one section of our garden. Walking the Avenue Gardens beneath our giant old-man pines was a significant safety risk so we redirected the routes to skirt around that area. But brave souls still turned up to visit.

On Thursday morning, the place was a mess. Nothing big came down but everything loose, small or dead certainly did. Never have I been so grateful to our small team. By 8am the next morning, we were all out doing a rapid clean-up. Zach was on the motor blower, Lloyd was vacuuming the lawns with the lawnmower, Mark was scooping all the debris out of the freshly cleaned goldfish pond and sweeping the sunken garden and I was reopening the Avenue Gardens. Soon after 9am, there was little evidence left of the storm damage and even I was impressed at the speed and efficiency with which we managed the restoration of order and garden decorum.

Zach and I have already scoped out patches of blue Iris sibirica we can raid to extend the patch in the park that is flowering so prettily

At 5pm today, we will bring in the flag and signs and close the gates. We have no intentions of opening for more than the ten days. Festival is most affirming for us. We are delighted that people come and respond to what we have here and clearly enjoy their visit. The praise is balm to our gardening souls. It will sustain us for the next 355 days. Tomorrow, we will be back out in our gardening clothes (looking more like old tramps, if I am honest), masks put aside for trips off the property only and moving more Sibirican irises down to the meadow by the stream. There is plenty to keep us busy.

Footnote: it appears our Covid-free honeymoon is over. It has been found in wastewater nearby so we now go into a holding pattern as we wait to find how much Covid we have in our area.
