Garden Lore

“America owes its 200 million starlings to the American Acclimatization Society which, under the chairmanship of New York pharmacist Eugene Schieffelin (eccentric or nutcase depending on your opinion), set out to introduce to America every bird species mentioned in the plays of Shakespeare. Shakespeare makes about 600 mentions of 50 different birds in his plays…. and starlings appear only once, in Henry IV, Part 1…. but it was enough to get 100 starlings released in Central Park, and the rest, as they say, is history.”

Garden lore: armillaria

In last week’s column, I said that few fungi will kill their host. Unfortunately one that can and does is the pesky armillaria. Generally this starts on dead wood but has an alarming capacity to spread below ground and take hold on perfectly good, growing plants. Armillaria is the main problem with cutting off woody plants and leaving the stump and roots where they are in the ground. If this fungus turns up as part of the decomposition process, you run the risk of it attacking the healthy plants around and once it has taken hold, you usually have to let it run its course over the next few years. It has been a significant problem in kiwifruit orchards where internal shelter has been taken out and stumps left behind.

Sometimes it is possible to get a stump grinder in or to manually dig out stumps. In other situations, we have to risk it and leave stumps to rot naturally. We appear to have three different types of armillaria in this country. These mushrooms develop a distinctive skirt on their stems below their caps, but by the time you identify that, the fungus has taken hold. The caps we see on top are little like the tip of the iceberg. It is the capacity to spread below ground that makes control very difficult, with long tenatacles called rhizomorphs. These are often described as looking like bootlaces, hence the term bootlace fungus. On the bright side, armillaria is apparently edible.

The fascination of fungi

Fungi are very curious growths. Each autumn I find myself taking a few more photos of exotic looking fungi and wishing I knew more about them. It turns out that there is a whole lot to know about them – the potential for a lifetime of study, even. I lack the rigour let alone sufficient years ahead so I have to make do with random facts.

We have a culturally instilled fear of odd fungi in this country – anything other than field mushrooms really – and this even has a name: mycophobia. This may come from our predominantly British forbears although, curiously, it appears that the traditional Maori diet did not include fungi as a staple food. I even found an article which talked about “the new science of ethnomycology” which, lest you wonder, is the study of attitudes of different ethnic groups to mushrooms. Apparently the Russians are the greatest mycophages or lovers of mushrooms and they recognise over 90 different edible wild varieties*. If we lived in France, we would be able to pop along to our local pharmacist to have our foraged fungi identified but such expertise is rare indeed in our country and foraging is actively discouraged.

In fact very few wild fungi are scarily toxic. We have the death cap mushroom in this country but it is quite rare. That said, it has been recorded beneath oaks and chestnuts in both Hamilton and Cambridge. You have been warned! Amanita phalloides is common in Europe in their woodlands and even very small quantities are deadly. Apparently it smells quite sweet and can be confused with the straw mushroom which is widely harvested in Asia.

However the scarlet flycap or fly agaric (Amanita muscaria) is relatively common and we have it in our own garden here. It is one to be cautious around, certainly with children, because it has been immortalised in all sorts of ways from Alice in Wonderland to gnome gardens. My understanding of toxicology is nil but I suspect the hallucinogenic varieties are often categorised with the toxic ones. Certainly this one is hallucinogenic, as a number of fungi are. It may be toxic as well, though as its use has been traced back to Ancient Greece, it doesn’t seem to be fatal. The consumption of hallucinogenic mushrooms has a rich history through many cultures and religions and there are suggestions that controlled usage may have been a factor in some well-recorded religious visions.

The scarlet flycap is not what is commonly referred to as the Magic Mushroom in this country (it is much more anonymous in appearance) but I am not going to go into details on that one. The banning this week of synthetic highs may see a return to wild collections, with all the inherent risks.

I thought I had photographed the wood-ear jelly fungus (Auricularia cornea) but I couldn’t find it. It is a flabby grey affair, a bit like bull kelp in appearance and was the source of a thriving export industry to China, back in the 1800s. I think it is safe to assume that one is both easy to identify accurately and edible but I admit I haven’t tried it yet.

Given that I buy dehydrated fungi of both European and Asian origin for use in cooking, maybe it is time I overcame my cultural mycophobia and set about learning which ones are edible in my environment. Instead, I just enjoy looking at the brief appearances of a host of different fungi around the garden, most here being related to the entirely natural process of the eco-system and the cycles of nature. Just as very few are deadly poisonous, few too are those so pathogenic that they will kill their hosts. Most are beneficial and some are highly decorative.

No wonder Alice declared matters becoming “curiouser and curiouser” after nibbling on the scarlet flycap mushroom. It applies equally to the fascinating wider world of fungi.

Plant Collector: Nerine pudica

Nerine pudica

Nerine pudica

How pretty is little pudica? This is the first season I have seen it flower and it is a delight. The pointed bells are mainly white with a pink stripe down the centre of each petal and each stem has up to six flowers on it. It is a nerine which makes it a bulb, but it is a much smaller one than the more common sarniensis and bowdenii types. The foliage is also much finer and narrower. It looks more a mondo grass or liriope leaf.

N. pudica is a species, hailing from the western side of South Africa. The ever-useful reference “Bulbs for NZ Gardeners and Collectors” by Terry Hatch and Jack Hobbs tells me that it is one of the original parents of many of the modern hybrids. While showy hybrids have their place, there is often a simple charm in the original species. The ones in the photograph are still in pots. It will take several years before we can comment on how reliable they are as garden plants in the rockery but the requirements are the same as for other nerines – excellent drainage and full sun. I am hoping they will do well because it makes a pretty addition to the autumn bulb display.

Garden Lore

“Did you ever meet a gardener, who, however fair his ground, was absolutely content and pleased?…Is there not always a tree to be felled or a bed to be turfed?…Is there not ever some grand mistake to be remedied next summer?”

Magnolia Sweetheart (AGM)

Magnolia Sweetheart (AGM)

It was a nice surprise this week to discover that Britain’s Royal Horticulture Society has conferred an Award of Garden Merit (commonly called an AGM but not to be confused with annual general meetings) on our Magnolia Felix Jury. This is assessed on how it performs in UK conditions so it is not particularly relevant to NZ. Two of our flagship magnolias – Vulcan and Iolanthe – perform consistently well here but don’t like the cooler, greyer conditions over there. But any international recognition is gratifying.

Mark named the plant for his father, Felix, because it was what the latter had been aiming for in his magnolia breeding and it was only possible for Mark to achieve it by building on the work his father had already done. There are only four other NZ deciduous magnolias which carry an AGM. Athene and Milky Way are earlier hybrids from Felix Jury. Starwars was bred by the late Os Blumhardt in Whangarei and is still widely sold. We have seen it flowering in both Northern Italy and the UK and it looked better there than it does here, in our opinion. And finally, Sweetheart was raised by Peter Cave (formerly Cave’s Tree Nursery near Cambridge) and remains one of the prettiest small to medium-sized pink flowered magnolias that we know.

Camellia Water Lily (Felix Jury)

Camellia Water Lily (Felix Jury)

Long before the Jury name became associated with magnolias, there were the Jury camellias. There are rather a large number of these because there were actually two Jury brothers breeding them at the same time and a market which was very keen on new releases. These days we find that most of the Jury camellias are attributed to Felix when in fact the lion’s share was bred by his older brother, Les Jury. In his later years through to the 1980s, Les Jury had the greater reputation, partly because he entered an arrangement with the powerhouse nursery, Duncan and Davies, to distribute his material internationally. They took over the material from his breeding programme and continued to name and release cultivars well after his death.

By the time Mark Jury (Felix’s youngest son) showed an interest in 1980, Les Jury was elderly. He had little contact with Felix but was particularly encouraging to Mark, giving advice and making suggestions.

This made three Jurys on the quest for new camellias at the time of their heyday in New Zealand. In camellia terms, these were heady times. Only roses ranked higher in popularity, measured by sales volume. It was a rare garden in this country that lacked several camellia plants. This meant there was a substantial local market. In addition to that, there was considerable interest from overseas, particularly the USA, and both Les and Felix picked up awards. Camellia societies were very strong and both men were active at local and national level.

At the time when Les and Felix started breeding camellias, the range was dominated by large old varieties of Camellia japonica which grow so easily throughout New Zealand. Alas many of these don’t like the bright sun and the foliage can turn yellow. Worse is their failure to shed spent blooms so they are often covered in a mass of pink, red or white flowers interspersed with sludgy brown. Examples of these early japonicas can still be found, particularly on abandoned rural house sites where nothing survives but the house chimney and huge old specimen camellias.

Camellia Jury's Yellow (Les Jury)

Camellia Jury’s Yellow (Les Jury)

Nowadays, we wouldn’t even consider naming a camellia unless it was self grooming (the term used to describe dropping spent blooms) but it was a breakthrough fifty years ago. It was the extensive use of C. saluenensis that brought this characteristic to the fore. In addition to that, Les Jury liked large, showy flowers in abundance and was keen to extend the colour range. With the passage of time, he is probably best known for ‘Jury’s Yellow’. It isn’t a true yellow camellia but it came before the yellow species were even known to the west. Mark remembers him talking about his theory that he could get the stamens to bleed colour into surrounding petaloids and that is what he achieved in ‘Jury’s Yellow’ – a white camellia with pale yellow petaloids in the centre. Had Camellia ‘Sir Victor Davies’ been a better growing shrub (and given a more appealing name but it was labelled thus by Duncan and Davies management after Les’s death), he might have been similarly remembered for one of the early purple breakthroughs. I am particularly fond of his ‘Antique Charm’ which moves pink along the colour spectrum towards apricot. I should comment that Les gave this cultivar to Mark under the name of ‘Antique Rose’ but the Camellia Nomenclature only records ‘Antique Charm’. Alas there is nobody left to clarify whether they are one and the same.

Camellia Dream Boat (Felix Jury)

Camellia Dream Boat (Felix Jury)

Felix Jury also looked for self grooming characteristics and large flowers and he had a love affair with the formal shape. His most enduring cultivars fall into that category – ‘Water Lily’ was an early selection and is still around but it was ‘Dream Boat’ that seemed to capture the imagination of the gardening public. The incurved petals of the latter give it a distinctive appearance. We rate his ‘Mimosa Jury’ as probably the most beautiful flower he named. It is a very pretty shell pink and shows good weather hardiness in our conditions. Added to that, it has a particularly long flowering season. Felix clearly liked it because it is named for his wife (although equally, it may have been she who laid claim to naming rights).

‘Rose Bouquet’ is another that has stood the test of time. It has an abundance of large blooms which are rose form and rose coloured. It has been described as the closest thing in appearance to an herbaceous peony that can be grown in our climate.

Camellia Itty Bit (Felix Jury)

Camellia Itty Bit (Felix Jury)

Arguably, ‘Itty Bit’ was the most significant breakthrough from Felix Jury. Most of the japonicas and the hybrids that Les and Felix named grew to be substantial plants. After a few decades, some of the original plants are sitting around the four, five or even six metre mark in our conditions. As town gardens shrank in size, the demand grew for smaller growing plants. ‘Itty Bit’ was a breakthrough – miniature flowered and miniature growing. It has never reached more than a metre to a metre and a half, though there are sister seedlings here that are substantially taller. This is less desirable in colder climates because this type of plant is just too slow to grow, but in this country, camellias that flowered profusely but stayed small and developed a natural bonsai form opened up new possibilities for use as garden plants.

The plant world is as driven by fashion as any other sector. By the time Mark started breeding camellias, he was reading the signs that the market wanted an abundance of small flowers on smaller growing plants. The love affair with the japonica was waning and New Zealand gardeners were working out that many of miniature flowered varieties then available grew into huge plants. The first project Mark undertook was saturation coverage of an established C. pitardii in a nearby garden but he was also after scent. He was reasonably dismissive of his first selection – Camellia ‘Fairy Blush’. While he rated it as a pretty little flower with good scent, it was open pollinated, not a controlled cross. The seed came from C. lutchuensis and appears to be a cross with C. pitardii.

Camellia Fairy Blush (Mark Jury)

Camellia Fairy Blush (Mark Jury)

Even today, twenty years after we released it, we still regard ‘Fairy Blush’ as the one that got away from us. If we knew then what we know now, we would have applied for plant breeder’s rights. It is particularly galling when Australian nurserymen tell us how well they do out if it. The realisation that it shows no ill effects from petal blight is an added virtue. Being small leafed with red new growth, satisfyingly fragrant, and with an extraordinarily long flowering season of several months, ‘Fairy Blush’ has many positive attributes. We find it makes a particularly good hedge, clipped to about 120cm.

Camellia Volunteer (Mark Jury)

Camellia Volunteer (Mark Jury)

Ironically, the second most successful selection of Mark’s was another chance seedling. ‘Volunteer’, as he is wont to say, volunteered itself. It was amongst the root stock to be grafted when it first bloomed and it was clear that it was something different. The solid flower is a pretty white and pink bicolour at the start of the season, deepening to a white and red combination as the season progresses with late flowers having the same anemone form but in red with no white. It is clearly a japonica and was named for the United Nations International Year of Volunteering in 2001.

Of his controlled crosses, ‘Jury’s Pearl’ is probably the one that has pleased Mark the most. The cream to palest pink flower has an opalescent glow which lights up dark areas of the garden and the peony form means it is a pleasingly full flower.

Camellia Jury's Pearl (Mark Jury)

Camellia Jury’s Pearl (Mark Jury)

Mark was in full flight hybridising camellias and had named and released eight different cultivars (now ten with two recent additions) when the news came that petal blight had reached New Zealand. We both remember the day, about twenty years ago, when senior members of the local branch of the Camellia Society arrived unannounced to break the news. Mark understood instantly what it meant. He stopped working with camellias and turned his attention to michelias (now magnolias) instead.

It took a year or two for Ciborinia camelliae to arrive here at Tikorangi. We collectively held our breaths and hoped that it would only affect late season blooms but it has settled in to making its appearance at the end of May or the very beginning of June which is the start of the season for all but the sasanquas. The effect has been devastating and cut the floral display substantially. Controls are not practical. Petal blight is a fungal spore which appears to travel unimpeded at least 5km in the air. The camellia is such a ubiquitous plant in this country that even if we could clear our own property, we would get reinfected from the neighbours. It was apparent we had to learn to live with it. Alas the worst affected types are the large flowered, show blooms so valued by both Les and Felix Jury. To keep a good display on these types of camellias, we have to groom the plants. The sought after characteristic of self grooming doesn’t apply with petal blight. The flowers stay solid, turn mushy brown and hang on unless removed by hand. This type of grooming is not a problem if you only have one or two plants but we have hundreds. Camellias here are used as utility hedging plants (both clipped and casual), wind breaks, small trees, back of the border fillers, topiary, clipped feature plants both large and small – they are wonderfully versatile in our conditions and we have too many to groom.

Only now, after two decades of petal blight, is Mark turning his attention back to camellias. We have not found any evidence of camellia petal blight on any of our sasanquas. Red blooms carry the disfigurement better. But above all else, the stars are the miniature flowered types which set a mass of flower buds over a very long period but where each bloom is short lived. It is not that they are immune, though some show a level of resistance. It is just that the individual blooms fall before they are taken out by the blight so the floral display remain clean.

Camellia Roma Red (Mark Jury)

In fact ‘Fairy Blush’ probably remains the very best camellia performer we have in the garden. It may forever be the one that got away from us but it is also the marker by which we will measure the next generation of camellia hybrids bred for the post Ciborinia camelliae era. I recall the customer who asked: “You know how Fairy Blush flowers from April to September? Do you have one that flowers from October to March?”. “What? A camellia?” I replied. “Yes,” she said. Such a question ranks alongside those customers who, looking at a plant in flower, ask: “Does it come in any other colours?”

As there are at least 71 registered cultivars attributed to Les (not including variegated sports), it seems excessive to list them all. Not all are significant and even fewer are still commercially available. Full details are available in the Camellia Nomenclature. A short list of his more popular cultivars would include ‘Anticipation’, ‘Avalanche’, ‘Ballet Queen’, ‘Debbie’, ‘Elegant Beauty’, ‘Jubilation’, ‘Jury’s Yellow’ and ‘Les Jury’.
