A trip to Baotai Mount

Baotai (16)
We returned from China last week, but alas brought with us a bad dose of Chinese flu which has kept us laid low ever since. Very low, in fact, but we are inching our way back to the Land of the Living.

Baotai (14) The International Camellia Congress in China was certainly an extraordinary experience.

We travelled around in matched purple coaches – seven or eight of them in total – headed by a police car, with another police vehicle and ambulance bringing up the rear. And as we made sedate progress (often travelling at about 40k/hour) with police on hand at every intersection to stop traffic that we might have unimpeded progress, all I could think was that we resembled the stately galleon from the old Joyce Grenfell song (“Stately as a galleon, I sail across the floor…”). Either that, or a ponderous, purple mechanical dragon.

On the day we headed off to Baotai Mount, in Yongping County, we transferred to small coaches for the mountain roads – a fleet of somewhere near 20 of them sailing through the countryside under police escort and all with hazard lights flashing. You know you are part of something unusual when villagers come out in numbers to line the roads to see what is happening!

Baotai (3) The day promised a four hour journey to Baotai Mount, the unveiling of The Stone Monument, tour of primitive camellia forests, mountain azalea, red lotus flowers and more in the natural landscape. The unveiling happened at lightning quick speed as most of us strolled up to the vibrant welcome. With a huge turnout of locals, it began to dawn on some of us that maybe WE were the exhibits, the sight to see on this occasion. China is a country driven by huge domestic tourism where foreigners still have novelty value.

Do not smile at the sight of the medical support team. While it is true that such events as the International Camellia Congress attract an older demographic who may well be prone to the occasional heart attack, there were also altitude issues on Baotai Mount. There seemed to be some debate as to whether we were at 4000 or 6000 metres, but given that NZ’s tallest mountain, Aoraki Mount Cook, is less than 4000 metres, we were a fair way up and some folk were certainly suffering, needing oxygen.

Baotai (34) After lunch, we wandered in the woods of ancient reticulata camellias – primarily Lindl. Most of the wander was on a four metre wide paved walkway, but it is different in a country with a massive population. There wouldn’t be much nature reserve left if thousands, hundreds of thousands or more feet were able to trample root systems in the wild.

Baotai (19)
There was a Magnolia campbellii in full bloom at the visitor’s centre which was such a delight that we will only whisper that it wasn’t a particularly good form of that species.

Baotai (47) We never did see mountain azalea and red lotus flowers though Mark was pleased to see a little Daphne bholua growing in the wild. Sometimes you just have to go with the flow and embrace the unexpected. Botanical variety may have bypassed us on this occasion, but I will never forget the unexpected sight of four soldiers (Red Army?) marching through the ancient camellia woods on Baotai Mount. You don’t see that sort of thing back home in Tikorangi.

And then we drove the four hours back to Dali for dinner.

Tikorangi notes: Off to China!

A random tui nest found yesterday

We leave for China tomorrow. Well, a small part of China – the south eastern area. Foshan (near Guangzhou), Dali Old Town, Jinghong and Kunmimg. The draw card is the International Camellia Congress which will make travelling much easier than doing it on our own.

Many of the plants we grow originate from these areas of China. We are hoping to see the yellow camellias in flower. Five years on from when I wrote about C. chrysantha, the other yellow species we have here still have not bloomed. But we may also catch some of the deciduous magnolias, wild azaleas and michelias in bloom. With our closed borders in New Zealand, the new species of michelias that have been discovered in the wild are not in the country and may never be admitted so it will be interesting to see what we are missing.

Being old enough to remember when China was closed to most of the world, I am not totally surprised to find that they still have in place the electronic equivalent of the Great Wall or the more recent Berlin Wall. I may only be taking my tablet as a back-up for photos because I see my most-used sites are all blocked – Twitter, Facebook, Gmail and Google. It is likely that there will be on-line silence until we return at the end of the first week in March.

While on the subject of China, I checked back for the piece I wrote in 2010 about Rewi Alley. It gave me cause to ponder how quickly our modern print and electronic media both moved away from longer-form writing to snappy short pieces with photos. I can’t imagine a NZ newspaper publishing a piece of that length any longer. But there are some interesting quotes from a personal letter from Alley to my late mother-in-law.
The photos today are the start of a little exercise in colour combinations, which we have spent some time discussing as we plan our new summer garden plantings. I am a big fan of blue and yellow in interior colour schemes (our dining and TV rooms are indeed soft yellow and French blue). I have long wanted to try a blue and yellow border in the garden, but now think it will look too contrived for what we want.

Yellow can be a difficult colour so I gathered a separate selection of cerise, magenta and orange blooms. Mark keeps pointing out to me the problems of adding yellow to this sort of colour mix – bright yellow at least. It is the one that can upset the apple cart of harmonious colour combinations. We may be quarantining our yellows to one area or at least using with extreme restraint.

Finally, as I was montying in the rockery, I was pondering how much modern gardening expectation has been shaped by two factors – the motor mower and glyphosate. Back in the days when grass was scythed and weeding was all done by hand, the current standards of the perfect lawn and the weed-free garden would have been inconceivable. It seems… unfortunate, shall I say… that the commonly held measuring stick for judging gardens today is predicated on two inventions, both of which are really bad for the environment.

Simple pleasures – hydrangeas in summer

One of the You-Me series of hydrangeas

What would a Tikorangi summer be without hydrangeas? They are one of the easiest and showiest of summer flowering plants here. Much of that is due to summer rain. We are blessed with both high sunshine hours (higher than Auckland, I like to point out) but also regular rainfall and hydrangeas do best in moist conditions.

We have the usual macrophylla mop tops which often feature in older gardens, with their big heads of blue or white. These we use more as background plants but hydrangeas are a large family and there are many more interesting variations than often realized.

Hydrangea quercifolia ‘Snowflake’

Most hydrangeas hail from Asia, particularly Japan, Korea and China but the oak leaf species, H. quercifolia, is a toughie from USA. The double form of this plant, ‘Snowflake’, is particularly showy. The abundant flower heads hang like cones, with each bloom forming multiple layers of petals down the stem. While it opens white, over time it ages through shades of soft green and antique pink before drying on the bush to a buff colour. It can look as if they are made from paper or silk and the flowers last right through the summer season into winter.

Hydrangea serrata ‘Preziosa’ changes flower colour through the season

We looked at a vast collection of H. serrata in an English garden and were very taken with the more refined appearance of this branch of the family. We have had the serrata hybrid “Preziosa” in our garden for many years. It starts flowering in November, coming out lime green, ageing through cream to white before turning pink and then red by the end of the season, often showing a range of colours on the same bush at any one time. The serratas are generally colour stable, unlike many macrophyllas. I want more serratas when I find the right spaces, particularly the daintier lace-caps.

We prefer Schizophragma hydrangeoides to the climbing Hydrangea petiolaris

When it comes to climbers, we favour the close hydrangea relative, Schizophragma hydrangeoides, over the more common climbing Hydrangea petiolaris. We have them in pink and white and they dance in the breeze with a lightness that petiolaris lacks, as well as flowering more profusely in warmer climates. Give them something to climb up and they will stick themselves to it.

Hydrangea ‘Immaculata’ – a top performing compact, white macrophylla

If you are a fan of macrophyllas, I can vouch for the top performance of “Immaculata” which is a compact growing bush with beautiful white mop top blooms. I am also extremely impressed by the new You-Me series that has come from a Japanese breeder. We have four different ones and they have names like “Forever” and “Eternity” and I lost the names so I don’t know which is which. But they are all very good with compact habit and such lovely flowers – semi-double lace-caps in the prettiest shades.

The magnificent tree hydrangea, probably a form of H. aspera

The season will close out for us with the huge, unusual, evergreen tree hydrangea that I see is now classified as belonging to the H. aspera (syn. villosa) group and sometimes given the cultivar name “Monkey Bridge”. At over five metres tall, it is large. It is also brittle so needs protection from wind. And somewhat frost tender. This is not a plant for everybody. But those huge lace-cap flower heads in early autumn are showstoppers and the flowering season lasts for a long time. Each flower head can measure up to half a metre across with colouring in subtle antique shades. I love it.

A word on the thorny matter of turning hydrangeas blue or pink… why bother? Gardening should be about working with nature, not trying to outwit it. In Taranaki, our hydrangeas are largely blue, very blue – the sort of blue that folk with pink hydrangeas envy. Yet I found myself charmed by the pink hydrangea display in a Canberra garden centre.

It is many of the macrophyllas that have colour determined by soil conditions. In acid soils (where rhododendrons thrive) they are blue, in alkaline soils they are more likely to be pink. It is actually to do with the available aluminium, an element that is usually strong in acid soils and absent from alkaline ones. Surely it is better to live with what we have and just admire the alternatives elsewhere?

The good news is that in a time of declining specialist, mail order nurseries, you can still source many of the less common hydrangea varieties as well as good selections of more usual types. Woodleigh Nursery was originally set up by Taranaki plantsman, hydrangea expert and personal friend, Glyn Church but is now in the capable hands of Janica and Quin Amoor. Their website is good and easy to use.

Hydrangeas are invaluable plants for easy-care summer gardens where there is enough moisture in the soils and, ideally, semi-shade. An annual winter prune tidies them up and gives larger blooms but you don’t even have to do that if you don’t want to.

Plants for dry shade – for Radio Live listeners and others

Scadoxus multiflorus ssp katherinae, beneath a canopy of rimu, pine and nikau

After talking to Tony Murrell on Radio Live this morning, here is the quick list of some of the plants we have found we can grow in our dry shade areas.

Bulk cheapie fillers (and many gardeners need these to get some quick coverage)
ajuga
phlomis
francoa (the bridal veil plant) – both ramosa and sonchifolia
impatiens
pulmonaria
mondo grass and lirope
scuttellaria

Triffids (for those who have B I G space to fill
Fruit salad plant (monstera delicosa)
various plectranthus but they need to be kept under control
philodendron
(short list – we are not too keen on many triffids here)

Shrubs
evergreen azaleas
vireya rhododendrons
cordylines – both natives and some of the more tropical varieties
hydrangeas – on the outer margins
some of the small palms – Lytocaryum weddellianum (the wedding palm or feather palm) is one that is performing well in our shade in several places.

Building up the planting areas beneath huge rimu trees

Natives
renga renga lilies (arthropodium)
ferns – many and varied
dracophyllum latifolia
parsonsia (native jasmine)
tree ferns or pongas which just arrive these days
nikau palms (we planted the first ones, now they just seed down and we keep those which are not in the wrong places)
astelias – bush species including A. fragrans
widow-makers – collospermum which also just arrive of their own accord
cordyline – particularly banksii

“Backbone” plants
ferns
clivias
farfugium and ligularia of various species
ferns
hostas
helleborus – particularly x sternii and also foetidus (better than the more common orientalis in full shade)
dicentra (can’t keep D.spectabilis going here but D.eximia does very well
zygocactus
and did I mention ferns? Lots of different ferns, both native and exotic.

Choice treasures and bulbs and high interest plants
scadoxus – puniceus and multiflorus ssp katherinae
cyclamen on the margins but not into the deeper shade
Soloman Seal – Polygonatum multiflorum
arisaemas
veltheimias
hippeastrum – particularly aulicum but papilio is also looking promising
trilliums
haemanthus albifloss
Crinum moorei – even better is the variegated form of C. moorei
bromeliads
orchids – cymbidiums, dendrobiums, calanthes
Paris polyphylla
streptocarpus

Other points from my conversation with Tony Murrell (love that man – he is so easy to talk with and so enthusiastic about plants):

If you want bluebell or snowdrop woods in the English style, remember they are mostly beneath deciduous trees. In New Zealand, evergreens dominate and our shady areas remain shaded all year round.
Lift and limb the canopy trees. There is not a lot that grows in deepest shade so you need to keep the canopy higher to allow light.
We are completely frost free in our shade areas but even gardeners in colder parts of the country may be surprised what they can get away with in terms of more tender material beneath evergreen trees.
While many of the plants we grow are epiphytic or have epiphytic origins (in other words, they don’t have big root systems below ground but will often be happy settling in forks in the trees), it is still necessary to build up soil at ground level to allow many plants to get established. The big trees suck up all the moisture and goodness from the ground and small plants find it very hard to compete. If you find it hard to dig into the ground because of the existing roots, plants will find it equally hard to get their roots in.
We raise beds by using mostly found items like old tree trunks, ponga logs, rounds of sawn timber – anything that looks natural (NEVER tanalised timber!) In dry shade conditions, they last a long time.

Our shade areas are low maintenance and generally self sustaining, We don’t water, we don’t spray, we don’t add fertiliser. Very few weeds grow in the shade, especially with the thick mulch that builds up over time. All we have to do is tidy up bigger bits of falling debris and carry out a bit of general maintenance.

I have written about many of these plants in earlier posts – use the search engine box on the right hand side if you want to check them out in more detail.

Again, building up beds beneath the rimu trees, using ponga logs in this case that have already lasted decades

‘Editing’ the plants for a lower maintenance garden

A few years ago. It is amazing how much the skyline of trees has changed since. My feet.

Editing, dear New Zealand readers. Cleaning up the borders and beds is often about editing the plantings. I know this because I read a certain amount of British garden media.

I have certainly been editing the plantings in the gardens around our swimming pool. It seemed a good summer occupation and on a few hot days this week, the flow between gardening and cooling off in the pool has been excellent.

The gardens were put in when we built the pool in the late 1990s and, in that clichéd way, we naturally opted for a sort of tropical feel. It was never thought out very well at the time. In the years since, I recall doing one relatively major rejig of the gardens but beyond that, they have only had the most perfunctory of care and minimal maintenance. This often included plugging gaps with whatever I had to hand. And it was showing that lack of attention.

I am a more thoughtful gardener than I used to be. I think that comes with experience. Knowing that we were unlikely maintain a pristine swimming pool, we had chosen from the start not to make it a key landscape feature but rather to site it discreetly where it is largely out of view. I am not keen on garish blue pools taking centre stage so ours is also a modest dark grey and we went with a black pool cover.

Curculigo, euphorbia and Ligularia reniformis, lush enough to pretend to be tropical and low maintenance

The upshot of this is that I figured we want a really low maintenance approach to the gardens around the pool and that it should be specifically targeted to the swimming season – which for us is mid to late December through to mid February. There is no point in putting in plants that flower outside that time because we won’t see them. Extreme editing was called for to eliminate my previous efforts to plug gaps and add seasonal interest with assorted perennials and bulbs.

I am quite happy with the earlier effort blocking up the Ligularia reniformis with Curculigo recurvata (nice foliage contrast and happily co-existing). We removed all but one of the damn dangerous euphorbia (E. mellifera, I think) which seeds far too freely and has disappointingly insignificant flowers but compensates with good form and foliage. Ligularia reniformis is getting to be a cliché in New Zealand gardens and I will restrict how widely we use it elsewhere in the garden, but it is very handsome and lush here, reaching well over a metre in height. However, the compact red dahlia hybrid will have to go. Not our style. Too suburban in our context.

Pachystegia insignis in the foreground, Xeronema callistemon behind and overhead a large Aloe bainseii

The Pachystegia insignis (Marlborough rock daisy) and Xeronema callistemon (Poor Knights lily) flower outside the summer season entirely but these native plants are not the easiest to grow in our environment and the plants are handsome and well established with good foliage contrast. Besides, it is not in our nature to edit our plantings down to a simplistic mass.

It is the next ten square metres or so where I have gone for a block planting. It was a mish-mash. No longer. I chose to use two common plants – the pretty but tough Dietes grandiflora and black taro. At least we know it as black taro but I am not sure if it is a colocasia (in which case it may be ‘Black Magic’) or an alocasia. It looks very new and raw at this stage, but I expect it to be a pleasing combination with plenty of pretty flowers next summer and good foliage interest. And low maintenance, without looking like a supermarket carpark.

Patience is a virtue. The freshly planted dietes and black taro.

I see some debate in garden media about whether digging and dividing perennials is necessary. Many folk seem to dread and shun digging – hence the no-dig craze for vegetable gardens. All I can say is that since I started doing a lot more digging and dividing, the garden looks hugely better for these efforts and the perennial plants thrive in more friable conditions with less soil compaction. It is also a learning experience as I experiment with plant combinations and think through the seasonal effects. It is a whole lot more interesting than mere garden maintenance and gives an opportunity to review and edit the plant selections. And it doesn’t even cost any money because I am working with plants already in the garden. There is nothing to fear from increasing the dig and divide regime.

And for those of you who don’t follow the garden Facebook page, I offer you my little study in dietes blooms. It makes no logical sense to float them in water, because they are not damp-loving plants at all. I just thought they would look charming, and they did – first in the swimming pool and then I gathered them all (slightly battered) to float them in the stream. Because I could.
