Sprinter (not yet Sprummer)

Tim Entwhistle from the Royal Botanical Gardens suggests we add two seasons to the European standards: starting out with the clunkingly named Sprinter, to describe late winter and early spring when most things seem to burst into flower.  He reckons non-Indigenous Australians can’t handle the complexity of the diverse seasons observed by Kooris, Murris, Nunga, Noongar and all the first people of this place.

He’s probably right.  The D’harawal calendar – from people south of Port Jackson – says roundabout now is the time of Wiritjiribin – cold and windy. I think I saw Acacia floribunda blooming today, so that fits.  But maybe, since its getting warmer, it’s closer to the time of Ngoonungi, the time of the gathering of the flying foxes?  “They come in from the north-east, the north, the north-west and the west, and swirl over the Sydney area in a wonderful, sky-dancing display just after sunset”, says the D’harawal calendar on the BOM.  No signs here at least, in Dharug and Guringai country, of flying foxes yet.

Let’s face it: I’m clueless.  I’ve got no idea about the local wildlife, know nothing of how you might live off the land, can’t even figure out half the Latin names of the flowers in our neck of the woods – Muogamarra,  Berowra National Park, Lane Cove.

Ok, I’m cheating. Lane Cove is miles away, but I took some nice pictures there yesterday.  And it is (mostly) on Hawkesbury sandstone.  And they have a great website for the local flora.  Which is important because this is what our plant identification book looks like:

All in all, I think I’m only up to Sprinter.

Possum pruning and chicken lawnmowers

I seem to spend a lot of time talking about animals behaving badly.  Or at least, animals doing sensible, survival enhancing things I don’t 100% approve of.  That means you, Treasure!  You can’t hide – I see you eyeballing that rocket!

But it’s not only the bowerbirds that do useful nibbling.  The chickens also make great lawnmowers.  Although, describing our patch of grass as a “lawn” is stretching the definition considerably.  I can’t say how delighted I was to read the advice recently from the RSPCA that “a weed lawn rather than a monoculture lawn is recommended for free range hens”. Anyway, thanks to the very dry winter, this year the backyard hasn’t turned into the Somme – we’ve got at least some grass and not just vast stretches of mud –  and the chooks are keeping the grass down just fine.

The same happy thoughts about animals as horticultural helpers come to mind when I inspect my NSW Christmas bush.  It has gorgeous pinkish red new growth which the possums seem to enjoy as much as I do, though their appreciation is expressed through the medium of chewing.   Every now and then they pop down and do some tip pruning for me.

Spider on Christmas bush shoot

Ceratopetalum gummiferum is mostly famous for its flush of red “flowers” in December (in fact these are sepals – the real flowers are smaller and white and arrive in late spring or early summer).  The consensus seems to be that if you lop off branches for festive decoration the tree will “flower” all the more enthusiastically the following year.  Vindicating the view that if you give an inch, people will take a mile, some even claim you can cut them way down low and they’ll come back.  Eventually.   I’m not planning anything as brutal as that, though I don’t really want mine to hit five metres and mess with my view.  Regular snipping is the go but since I’m secateur shy, how kind of the possums to do it for me.

Ornamental manoeuvres in the dark

I’m hip to the food forest concept but there’s only so much food you can grow in the shade.  Naranjilla, tamarillo, monstera, babaco, finger lime, warrigal greens – ticked all those boxes.  But at a certain point, you’ve just got to give up the dream of a waving field of wheat outside your kitchen window, and actually plant something that’s going to grow there.  Even if it means going over to the other side, down the slippery slope towards… the ornamental garden.  The garden you can’t eat but which ameliorates the existential despair of staring down at yet another sinkful of dishes.  Gardening in the terrain between utility and futility.

Just now quite a few of those spirit pleasing plants are in bloom.  Libertia Paniculata has made me very happy: a lovely native that flowers in the shade, and is even named after a female botanist and mycologist, Anne-Marie Libert (or Marie-Anne, depending who you ask).  Okay, you can’t eat it, and you couldn’t describe it as flowering copiously in its sheltered spot under the pittosporum (also blooming now).  But the delicate white flowers when they come – some in May and again in August this year – linger, picked out in the odd beam of light that makes its way between the ferns.

Plecanthus argentatus has been a stalwart too, sprawling a bit unless snipped back now and then, but you can’t have too much silvery-grey foliage in my view and it’s a rarity in shade-loving plants, so sprawl away, I say. It copes  well with dry weather and even produces small sprays of tiny white flowers in autumn.  I’ve had less success with indigofera australis which I hoped to plant alongside it – one cheap but sickly plant finally croaked recently after sitting there rather miserably for a year or so, and I failed to get any of the seedlings I sparked up from seed bought online to survive in the garden.  But I’ve noticed new growth on a second plant, put in last year, so I’m hopeful I’ll see some of its purple flowers eventually.

Vines are a good bet for shade, since they are usually happy to climb towards the light. I’ve got two varieties of pandorea jasminoides swarming up a trellised fence, entwined with Tecomanthe hillii.  The Fraser Island Creeper has done nothing flower-wise, which may well be a good thing, since I’m not wild about the hot-pink colour scheme (it was an impulse buy), although I do like the mauvy-purple of the new shoots.  There’s been a bit of action from the “Bower of Beauty”: though it’s decided to set up its bower of trumpet-shaped flowers on the neighbour’s side of the fence (in the sun, dammit!).

Pandorea pandorana, the wonga-wonga vine, flowers for a only couple of weeks a year – just about now – but with the occasional bit of cow poo it has done a good job of disguising the shonky engineering of our garage. Having seen “old man’s beard” going the full Ned Kelly in sandstone country up the way, I was a bit nervous about putting Clematis aristata over the car port, thinking the extra weight on the roof might crush our car like a bug.  But no – after a couple of years it’s barely hanging on.  I suspect that lime from nearby concrete might be the offender.

The correas seem to have done their dash more or less, so no pics.  Correa glabra, quite an upright small bush with fresh lime-green leaves and pale yellow flowers, and Correa bauerlenii, with greeny-white flowers in the shape of an implausibly towering chef’s hat, shiny dark leaves and reddish stems, have both grown well and flowered in a gloomy spot, though Correa alba struggled, never really growing much at all and finally giving up the ghost.  Another “Chef’s cap correa” did really well for a while out back but succumbed during a very wet February, so drainage seems to be a thing.

The correas apparently attract birds, but the plant growing in the shady front yard that has attracted the most attention, not just from our “house” birds, the red and little wattlebirds who dangle upside down to sip its nectar, but even the occasional beautiful visitor like the gorgeous rufus-chested Eastern Spinebill, is not a native but the abutilon, the chinese lantern.

I didn’t plant the chinese lanterns, but as time passes, I come more and more to like Val Plumwood’s idea of garden that is convivial – accepting the presence of foraging animal visitors and plants – local, native and imported – as long as they don’t go feral.  She was fond of daffodils – in part because the wombats and other critters that visited her garden didn’t eat them, and in part because they didn’t do a runner into the bush.  She was a smart lady: you have to respect anyone who survived a death roll with a crocodile.

Beyond the out-and-out baddies to be found in the noxious weeds list and the excellent Grow Me Instead booklets, it’s actually pretty hard to work out what to avoid if you don’t want to become notorious as the “Typhoid Mary” of the next generation of weeds.  I only know not to plant freesia, which I love, because of the fact they pop up everywhere at this time of year – in the wheel rut zone in the drive and the dog poo zone along the street.  The smell of murraya is gorgeous and it’s not listed on the plants to avoid pamphlets for around here but murraya paniculata “exotica” is a serious weed in South Eastern Queensland.  All sorts of scary things are for sale in garden centres and online, and there’s plenty to be worried about in my garden already (I’m going to have to hypnotise my neighbour if I want to uproot the avenue of seed-shedding agapanthus between our drives).  I try to grow local, but if all you can buy are hybridised natives, provenance unknown, perhaps you might be better off with some well behaved, hard working refugees from a South American rainforest or an English country garden.

Sweetness and light

On our shady south-west facing hillside (who went house hunting without a compass, then?) there’s just one spot that gets plenty of light year round: not a bad place for some solar panels on the top of a pole. But right in that spot there’s a native tree, sweet pittosporum or pittosporum undulatum.  And there’s a healthy specimen of the same species dead to the north of our kitchen windows, right where the winter sun might otherwise beam through.

Hornsby Council is pretty proud of its status as a leafy north shore suburb – “The Bushland Shire” – and dissuades its rate-payers in the strongest of terms from cutting down trees.  But not this one.  Until 2011, despite its status as a native, gardeners had a licence to kill sweet pittosporum, along with a select few imported nasties – cotoneaster, camphor laurel, privet and coral trees. But now it’s a different story.  You can chop down quite a lot in Hornsby these days – pretty much any non-native tree.  You can even gaily hack down Australian natives that don’t hail from this part of the Hawkesbury.  But put that saw down!  Pittosporum is now right there on that not very lengthy list of protected local trees, shrubs, grasses and vines.  It’s a dramatic turnaround, from big-league environmental weed to local hero, all in the space of a single year.

So what’s going on here?  Tim Low’s immensely readable book, “The New Nature: Winners and Losers in Wild Australia” (Viking, 2002), a fat but fascinating volume filled with stories about birds and trees, insects and frogs and their complex inter-relationships with human beings, has a lot to say about weeds and natives, and in fact quite a bit to say about sweet pittosporum.  The essential argument of the book is that any quest to preserve untouched wilderness or to maintain nature free from human interference is not just doomed, but essentially ill-conceived.

Human influence has been making plant and animal winners and losers in Australia for many thousands of years, and Low documents not only the way some pragmatic species capitalise on urban environments (think peregrine falcons nesting in high rise buildings) but the way many others rely on continuing human intervention (like firestick farming or stock grazing) to survive.  Sydney’s green and golden bell-frog survives at the Brickpits in Homebush, a location described as “one of the most industrially polluted in the Southern Hemisphere” (24) because these frogs are tolerant of high levels of heavy metals, while the frog-killing chytrid fungus is not. Low points out the limitations of the distinction between “native” and “exotic” as a way of gauging the impact of animals and plants on biodiversity, and argues that decisions about what to conserve and how to do it, are in short, very very complicated.  Koalas can be forest killers and cows can step into the gap left by extinct megafauna in maintaining diverse grassland.  As a greenie and a gardener, I found the anecdotes and ideas in “The New Nature” provoking and intriguing, making me take a good hard look at my weed anxieties and my fantasies of a bird-friendly, local provenance garden.

Hornsby Council’s change of heart about sweet pittosporum illustrates Tim Low’s arguments beautifully.  Don Burke, the Australian Native Plants Society of Australia, Grow Me Instead (The Nursery and Garden Industry Association) and the Queensland Government all agree that it’s an invasive weed. “The New Nature” with its ambivalence about such terms calls pittosporum “our worst native weed” (250), “replacing diverse systems with monoculture” (201).  While a canopy of eucalypts allows a rich understory, pittosporum shades out nearly everything else (although that nasty garden escape, privet, apparently copes well).  Birds enjoy the pittosporum’s orange fruits and disperse its sticky seeds.  Not needing fire or light to germinate, and tolerant of richer soils than many other natives, pittosporum is a native to this neck of the woods, flourishing on the shale ridgetops on Hawkesbury sandstone – most of which are now built on.  Run off from houses and gardens has enriched the sandstone soils on the slopes and pittosporum has moved on in.  According to Low, “If you take eucalypt forest, add fertiliser and water and take out fire, you have a recipe for rainforest.  The pittosporum invasion is really a takeover by rainforest” (248).

Pittosporum undulatum has its defenders.  Jocelyn Howell from the Royal Botanical Gardens suggests that pittosporum can shade out and outcompete other more troubling weeds (although Tim Low would argue that even invasive weeds like lantana can play their own role as a habitat).  Others argue for it in terms of the food supplies it offers and the fact that it *is* a local really. Obviously, Hornsby Council has plumped for this point of view.  Most of the advisories suggest that it’s a weed only outside its home range, using provenance to distinguish true locals from native invaders.

But according to Low’s arguments, its home range isn’t the home it once was.  His book gives poignant examples of Sydneysiders talking about the impact of pittosporum (“pittos”) in terms of solastalgia, the sense of homesickness you have when you haven’t left home, but your home has changed forever.  Orchids and grasses gone, along with the smell of eucalyptus (248).  There are no easy answers here: it’s “a hard one”, “one of the most sensitive issues around” (249).  Are the eucalypt forests of the Hawkesbury slowly morphing into (monocultural) rainforest?  Will the catastrophic fires I expect and dread drive it back?

From a more selfish point of view, it seems like my kitchen windows will remain gloomy and my solar panels a dream, even as my fantasy as a kid growing up in the arid lands of the South Australian mallee, of coming home to a rainforest seems to be coming true…

A hoarder’s confessions

Impulse buy online this week: Rock Samphire.  I set out to get a couple of extra galangal plants to join the one that’s doing well in a shady spot at the foot of a banana tree transplanted from my sister’s garden.  Galangal look great – too great to dig up for a Thai curry, it turns out. WIth three plants on the go I figured I might get up the courage to be more brutal next time I’m considering a tom yum.  This is one of the problems of the whole food forest concept.  Your turmeric plant, for instance, makes a terrific understorey plant which, if undisturbed, generates a gorgeous, long-lasting white flower.

Image   Galangal

A powerful incentive to leave the roots in the ground, and that’s leaving aside the tedious multistage process of actually making tumeric powder from the rhizomes.  Even a brief description of this sounds implausible at a number of levels: “sweating”, curing, drying, “polishing”?? removal of the “mother”?? With the passing of time, I am beginning to draw the conclusion that my painstakingly assembled collection of food plants functions more in the realm of the hypothetical or fantastical (“I could source all my herbs and spices in my garden if I really wanted to and/or when civilisation breaks down“) than in the practical domain of producing stuff for tonight’s dinner.  In fact, it’s a sort of epicurean hoarding.

So, with that revelation, back to the online plant acquisition.  It’s a slippery slope: once you’ve decided to order a couple of plants you think, well, since I’m paying for freight anyway, I may as well get a better bang for my buck.  Native mint Mentha Australis: looks and smells just like your bulk standard mint, it turns out.  Wormwood, for the chicken run, to deter mites.  The upside there is, if I lose another chook (possibly as a consequence of an infestation that artemesia absinthium alone fails to resolve), I can always chuck the wormwood some in some low grade spirits to make up my own absinthe and go out in style like a debauched French Impressionist while weeping over my decorative poultry corpse.

And on a whim, Rock Samphire, which along with the unrelated Marsh Samphire (both names a corruption of “St Peter” – it’s a rock reference) seems to be a thing in British wild foodie circles.  I’m always faintly nervous about bringing a new non-native into the garden, and this one is an umbrelliferae which often seem to be a bit weedy though useful for attracting hoverflies and the like.  But I reckon I should be okay with this one, since it grows naturally on exposed maritime cliffsides, presumably with plenty of sun.  Any escapes at our place, on the shady side of the ridgeline, are unlikely to enjoy their freedom.

When this one arrived, I realised that I had seen it before, at Worm’s Head on the beautiful Gower Peninsula in South Wales.

Seen it and, entranced by its delicate winter skeleton, taken loads of photos of it.  Today’s garden treasure, avariciously gathered, and yesterday’s digitised booty, reunited in the hoard.

Two easy steps to make your warrigal greens thrive

We had a break from the back garden this weekend, camping at Twin Beaches in Marramarra National Park on the beautiful drowned river valley that is the Hawkesbury estuary.  The east-facing wooded slope up the back of the camp site was object lesson in how to use the shade-loving local plants I’ve been bringing back into my garden over the last couple of years.  Particularly gorgeous was the swathe of prickly rasp fern, tendrils fresh and pink after recent rain, appearing through the grass and the dianella caerulea along the path to the dangerously repellant pit toilet.

Image

I haven’t yet managed to propagate a cissus vine – I am working on some cissus antarctica cuttings pinched from a nicely planted up children’s playground.  Since it is a national park and I am slightly neurotic, I would have felt guilty if I had snipped off some propagation material from the vine that wound its way through the trees – a slender young cissus hypoglauca, I believe.  Apparently you can cut the stems of the mature vine into sections and drink the sap that drips out like water.

Image

But most impressive was the dense carpet of exceedingly healthy looking warrigal greens growing only a metre or two back from the high tide line.  I did end up picking some to stave off the scurvy likely to be induced by too much camping food.  However it was a bit of a challenge to find a satisfactory spot for my ad hoc harvest, since the most vibrant and sturdy patches of tetragonia seemed to be in just those  places – a couple of steps from the fire hole, around the base of a convenient tree – that a bloke might choose to relieve himself after putting away a couple of long necks.  This may be a coincidence of course.  But nettles and lime trees seem to favour human urine as a tonic so who knows, maybe New Zealand spinach is the same?  I know it’s sterile and Romans used it to wash their togas and all, but I’m not completely sure I’m going to try this particular high-nitrogen fertiliser on the salad greens at home.

Absurd gardening prejudices pt.1

It seems I harbour a deep-seated suspicion of people who use epiphytes as a garden feature, something I discovered at the exact moment I transformed into one of them.  According to my brain, the sin of gratuitous staghorn display is gravely compounded by the location of said epiphyte on any kind of artificial structure, including but not limited to fences, trellises, wooden mounting boards and hanging baskets.  As far as the Chelsea judges in my head are concerned, such epiphytic offenses are right up there with non-ironic use of garden gnomes, concrete kangaroos, or indeed any form of arboreal statuary.

So, obviously, this – garden design by guano – is unimpeachable:

Image

But when bird-dropping inspired artlessness comes crashing down, what’s to be done?

Image

Well…. this might pass at a push:

Image

But this is just plain tacky, or so my inner hippie informed me just as I whacked in the last fencing pin:

Image

The garden, begun with an earnest utilitarian intent, has strayed from the straight and narrow of food production.  First it was the bird baths, those gateway ornaments, a thin veneer of ecological functionality only partly disguising their real purpose, as a visual full stop in the fernery (“fernery”??!).  Then it was the native grasses: “to promote biodiversity”.  Huh.  We will turn silently away from the mosaic stepping stones.  Even the companion animals are becoming disturbingly decorative:

Image

Clearly the shark was jumped long ago.  And to add insult to injury, this post has no political rationale either. No musings on death; no hot tips on organic gardening; not even a passing reference to climate change.  Utterly bereft of any skerrick of social utility.  Bugger it: I’m off to a garden centre for that replica of the Manneken Pis.

Do possums see in technicolour?

Tamarillos: what a great fruit for inept, part-time gardeners!  Stupendously quick to grow – to a couple of metres in not much over twelve months.  Producing a crop in less than two years and in a shady spot too, tucked in amongst monstera deliciosa, naranjillas and a dwarf Cavendish banana in the lee of the neighbour’s tall pine tree, with filtered light in summer and just a touch of winter sun.  The egg sized fruits are quite pleasant to eat: flesh with the texture of a honeydew melon and with an overtone of passionfruit.  I like the big bright green tropical leaves and the fact that fruit flies seem to leave them alone.  But best of all, Matimba (as our youngest named the baby tree when it went in) didn’t seem to be pestered by possums.  Since the fruits dangle  from slender pendulous branches I wondered at first if the critters couldn’t make it to where the action was.  Then I thought perhaps they hadn’t spotted them yet, remembering how my figs and beans went untouched for a year or two.

And then recently I spotted a green but nibbled fruit under the tree.  Obviously the contents weren’t to the liking of the thief – not quite ripe enough, perhaps.  It might well have been an optimistic bird that did the dirty work.  But given that tamarillo fruits quite distinctly change in colour as they ripen – gold in the case of Matimba and red in the case of her as yet non-fruiting little sister Molly – this evidence of mid-snack mind-change made me wonder: “Do possums have colour vision?

Image

I realised only recently that primate colour vision is actually pretty unusual amongst mammals, whose ancestors swapped technicolour for better night vision while hiding amongst the shadows, waiting for dinosaurs to leave the party.  Humans, primates and monkeys have a kind of gerry-rigged third cone that gives us an in on the neat seed dispersal system fruit-bearing plants sorted out with birds and their dinosaurian tetrachromatic eyes.  Like parrots, we can spot a ripe fruit against a canopy of green leaves (although we don’t get to see the UV spectrum, which is disappointing).  Okay, there are other explanations for primate colour vision – like spotting tasty red-hued fresh leaves – but I’m sticking with this one for now.  Interestingly, colour-blind humans, primates and monkeys (particularly males) are still unusually common.  It seems that colour-blind individuals are great at seeing through camouflage, so a sprinkling of dichromatic members of the group serving as predator-spotters does a mob of monkeys or apes no harm at all.

Pulling out of the fascinating vortex of animal colour vision research and returning to my original question, what about possums?  With the ubiquity of brushtailed possums in suburban houses and gardens in Australia, surely someone would have a definitive answer on this one.

It turns out that marsupial colour vision has been a hotbed of academic research over the last fifteen years.  Until the early noughties it was assumed that marsupials, like most placental mammals, were dichromats, with pretty limited colour vision.  But then researchers identified that some marsupials, like the fat-tailed dunnart, the honey posssum and the quokka, were trichromats (as indeed were the ancestors of platypus and echidnas, the monotremes).  Some marsupials, like the poor old tammar wallaby, do seem to have the same rather average colour vision as the placentals.

Brush-tailed possum vision is so cutting edge that Lisa Vlahos’ PhD on it, completed in 2013, hasn’t even been published in science journals yet.  But, based on the annual reports at the Vision Centre at ANU (sadly I haven’t been able to access her endearingly named PhD thesis “Possum Magic”) it look like brushtails can see part of the UV spectrum, but can’t distinguish between white and green light: more like dogs than chickens, they’re red-green colour blind.

Which might explain my chewed and rejected green tamarillo fruit. Or not.  But it was fun finding out anyway!

It’s not easy eating greens

Maybe it’s a careless-vegetarian-with-low-level-iron-deficiency thing, but I’m often hankering after greens. Thankfully, the green leafies seem to be one of the few foodgroups to which brushtailed possums, rats, bandicoots, brush turkeys and chickens – the non-human beneficiaries of my most of my horticultural efforts – all seem relatively indifferent.  When things were very barren in the yard recently, my sorrel plant, a marvellous perennial that, with the deep taproots of a potential weed, soldiers on with minimal attention, was munched by something with a sophisticated palate for citrus flavours and a high tolerance of oxalic acid.  Occasionally some beastie has a light snack on my other trusty standby, the rainbow chard, but on the whole my favourite  greens seem immune to animal predation.

Image  Image

Having failed to grow them from seed, the Warrigal greens I bought from Daleys have been a cracker.  They’ve threaded their way through a garden bed that, with only a couple of hours sun a day, has pushed the envelope for even shade tolerant plants like Davidson’s plum, macadamia and callicoma serratifolia.  Andy Ninja regularly scratches her way through that neck of the woods, grubbing for remnants of trad, but she hasn’t managed to loosen the Warrigal greens from their moorings, and we’ve had it in everything from lasagne to dal to quiche without any visible dent appearing in the supply.  Rumour has it that they self-seed prodigiously, so there’s promise of more next year.

During a couple of La Nina years we had watercress soup on the menu for about 18 months on the trot thanks to a semi-shaded spot near the chook run: boggy in torrential downpours but otherwise ordinary garden soil.  A soft spot for umbrelliferous flowers and the aphid eating critters they attract, and a lazy habit of chucking decrepit parsley plants under my fruit trees as mulch has meant that Italian parsley pretty much dominates the seed bed in the herb garden and food forest around the back door.  Whenever the moisture level and the temperature is right, a new generation surges forward underneath the potted makrit lime and the Cavendish banana and even between the paving stones.

I had rocket doing the same in the veggie patch a couple of years ago, until I put the kibosh on it by over-zealously collecting the contents of the papery pods.  I must have been indulging in some herbal fantasy of seed saving, and so I have feral rocket no more.  At least for the moment.  Because of the tedious necessity to earn a living, I’m never on top of the weeding, and as the years pass I’ve started to recognise the seedlings of my favourite plants wherever they appear so I can “edit” the garden rather than, in that hateful bit of business-ese, attempting to “grow it”.

Image   Image   Image

However, a particular favourite has proven to a more difficult proposition.  I love bok choi and all its cousins, but especially the look and taste of red bok choi, an F1 hybrid that’s really a luscious purple, a perfect match for the “house” beans, Purple King; the salad enriching Giant Mustard and the beautiful but apparently impossible to grow purple brussel sprouts.

I have spent far too much time, money and mental energy over the last three years trying to produce an anemia-busting harvest of bok choi.  In year 1, following the gospel of Jackie French, I tried to shelter my precious cruciferous greens in a guild of fellow travellers, with limited success.  In year two, I went for a guerilla strategy – my choi germinated under the cover of the great hairy leaves of my zucchini.  I was optimistic but the cabbage whites were not so easy to fool.  But I have made a break-through, thanks to a “chuck all the seeds in the bottom of the packets together and hope for the best” approach.  Coriander!  So impossible to grow in Sydney, always starting so well and then going to seed before you’ve even got a garnish out of it.  But apparently, you can keep the barn door closed (to moths? where is this metaphor going?) even if your coriander has bolted.  The bok choi that grew in amongst my incorrigible coriander was completely untouched.  So under the shelter of brush turkey-thwarting hoops of wire and the modest veil of a rather tattered veggie net, in goes bok choi and sacrificial coriander along with the aragula and the mizuna, the watercress and the daikon.  If I can crack this one, the purple brussel sprouts are next!
