The plant pathogen genus Phytophthora, a water mold with similarities to a fungus, is a worldwide threat to ornamental and commercially valuable plants due to how it can develop undetected in the early stages of an infestation. While there are some species of Phytophthora that begin an infestation on the above ground portion of a plant, a much larger portion of the approximately 170 known species of the pathogen start out destroying a plant from within its roots. Phytophthora moves upward from the roots through the water channels of the plant, interfering with the plant’s ability to absorb water as it goes. The effect makes the plant appear drought-stricken, which is essentially the case.
One of the plants heavily afflicted by Phytophthora in the past 30 plus years has been the cocoa tree, Theobroma cacao, and specifically the cocoa trees planted in western Africa, where most of the world’s cocoa beans are produced. The species of Phytophthora doing the most damage in that period has been Phytophthora megakarya, a disease that blackens the pods which contain the cocoa beans, rendering most of them unfit for consumption. This disease and a virus transmitted by mealybugs called cacao swollen shoot virus (CSSV) in combination have decimated cocoa tree plantations in western Africa in recent decades.

Phytophthora megakarya was introduced from the Americas, where it had long co-existed with the native cocoa trees. The cultivated cocoa trees of western Africa had developed for generations without having to cope with infestations from megakarya, though they had long been contending with Phytophthora palmivora, a less devastating disease for them.
CSSV was native to the forest trees of western Africa, where it did little damage because of long term co-evolution of the trees with the virus. The introduced cocoa trees had no inherited defense against CSSV, resulting in afflicted cocoa trees losing vigor and dying within a few years. Meanwhile, the ants that farmed the mealybugs for their sugary secretions have ensured they continue to live safe from predators by guarding them, even building shelters for them.
Chocolate has grown steadily more expensive, at a rate beyond ordinary inflation, due primarily to shortages of cocoa beans caused by these pathogens. Another reason for chocolate price increases has been related to the salutary shift away from indentured labor on cocoa plantations, making the price more accurately reflect the true cost of production. The cost of production is bound to catch up with any resource as nature asserts itself in one way or another, or in many ways, and imagining that we are immune or insulated from the effects of that assertion is mere hubris and folly. Ultimately, we will pay the price.

What kind of English word is “Winnemucca”? How about “taco”? “Fond du Lac”? People who get bent out of shape over other people speaking languages besides English while out in public in this country probably fail to realize how many English words have their origin in other languages. As much as 30 percent of English words are borrowed from the world’s thousands of languages. It would be difficult or impossible for the average English speaker to use only Anglo-Saxon words.
In the United States especially, where nearly 100 percent of the population comes from elsewhere in the world, the English language is a polyglot mixture made up of additions from languages everywhere, and yet it stands apart in its diction, its spelling, and in other ways. Place names preeminently use some version borrowed from the many Native American languages that have all but disappeared otherwise. What does it mean to send somebody back where they came from, when almost everybody came from somewhere else at one time? Send them back where? To Ohio? To Florida? If we go back far enough in time, almost everyone will have to leave, and the Native Americans – what is left of them – will no doubt feel immense relief, as of an oppressive burden lifting away from them.
The Tower of Babel, a painting by Pieter Breugel the Elder (c. 1525/1530-1569).
Exclusionary talk is loco chauvinism. It is meshuga, and yahoos who go on about sending others back where they came from are clearly non compos mentis. They should examine their own origins, which in the latest generation or two or three might be in places like Tulsa, Santa Fe, Tennessee, or Baraboo, but going back further could be traced to Scotland, or Frankfurt, or Sarajevo, and ultimately to Africa. White folks weren’t always white, and anyway no deity ever descended from the heavens to declare whiteness a superior trait. It only matters to people who are terrified of losing their imagined superior place in society, and must have Others to look down upon. Ordering Others to speak English when they are conversing among themselves is not only high-handed, it ignores how immigrants have enriched and informed English itself with words and expressions from everywhere. The proper remark for an English-only speaker to make in that case, if any is necessary at all, is gracias, or merci, or danke, or mahalo, or arigatô, or . . .

Johnny Cash (1932-2003) sang a North American version of “I’ve Been Everywhere”, a song written in 1959 by Australian country singer Geoff Mack, and which in the original version included all Australian place names, many of them originating in the languages of the Australian Aboriginal peoples.
In most of the country, daffodils (genus Narcissus) bloom in March and are among the first signs of spring. Some places might have blooms as early as February, and others not until April. In all places, the leaves pop up from the ground while freezing weather is still frequent, and inexperienced gardeners and curious onlookers worry that the plants have come up too early and will suffer damage from the cold. Not to worry. The daffodils have been through it all before and will be fine. Any damage they do incur from late winter weather usually comes from being bent down to the ground or snapped by the weight of a late snow or ice storm.
Deer, rabbits, and squirrels do not eat daffodil bulbs, foliage, or flowers since they are toxic. The plants spread by jumping from place to place by seed dispersal as well as increasing into clumps formed by daughter bulbs dividing from their parent bulbs, rather like offspring who have matured and set up housekeeping next door. Not all daffodils are noticeably fragrant, and as often happens with flowers it is the older, original varieties that are most fragrant, because plant hybridizers sometimes lose that aspect in pursuit of other traits such as size or color. Trade-offs.
Despite a substantial list of pests, fungi, and viruses that can adversely affect daffodils, in practice they should not gravely concern the gardener since the daffodils seem to cope well on their own. The worst condition affecting daffodils, particularly their bulbs, comes from poor drainage or excessive water, particularly in winter. Hardly anyone likes cold, wet feet, and daffodils are no exception. On account of the wet winter in most of the eastern half of the United States, daffodil displays may be subdued this March.
In the 1965 film Doctor Zhivago, a long winter finally turns to spring, heralded by a field of daffodils.
About the only thing an American gardener can say against daffodils is that they are not native to North America or to any part of the Western Hemisphere. Daffodils originate from southern Europe and northern Africa. That daffodils are not native here is an academic complaint, however, since the genie can hardly be stuffed back in the bottle at this point. Most of the people living now in the Western Hemisphere do not belong here, either, and it’s possible to argue they have done far more damage to the native habitat than anything innocent daffodils could have done. On the contrary, daffodils perform a great service everywhere because their trouble free disposition, loosening of hard soils, and cheerful announcement of spring give a greater portion to the gardener and non-gardener alike than they require in return.

“11 When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things. 12 For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known. 13 And now abideth faith, hope, charity, these three; but the greatest of these is charity.”

DNA kits are very popular now, both for people ordering them for themselves and for those giving them as gifts. Sales of kits doubled in 2017 over all previous years, and have increased again in 2018 over 2017. Interest appears to derive mostly from curiosity about immediate ancestors, on which the kits do a good job of enlightening people, and secondarily about genetic health risks, on which the kits dealing with the subject deliver mixed results, needing confirmation from a medical professional.
One area of controversy with the results, at least for Americans, has come from links to African ancestry for European-Americans, and links to European ancestry for African-Americans. Most European-Americans, or white folks, get results that include some ancestry going back to Africa two hundred years or more, usually less than 10 percent of their total genetic makeup. Most African-Americans, or black folks, get results that include around 25 percent European ancestry.

Tracing ancestry is easier in the pure bred lines and close quarters of Old Europe than in the melange of ethnicities and transcontinental migrations of the New World.
Compared to the ethnic homogeneity of most Old World countries, Americans are mutts, and the melting pot was particularly active in the years of heavy immigration from Europe from the mid-nineteenth century to the early twentieth century. Africans brought into the country as slaves until the Civil War eventually made up a larger proportion of the total population through that period than they have since, averaging close to 20 percent of the total for the first hundred years of the republic, and settling to a range of 11 to 13 percent of the total population afterward. It shouldn’t therefore surprise white people taking DNA tests to discover they have at least a small percentage of relatively recent African ancestry.
It is interesting, however, that DNA test results for black people yield an average of 25 percent European ancestry. It is not surprising there has been mixing of the races, despite laws against miscegenation going back centuries, but that black people have a much higher percentage of European ancestry than white people have a percentage of African ancestry, and yet black people are still and always considered black. This is Pudd’nhead Wilson territory, in which even a tiny percentage of African blood is tantamount to an entirely African genetic heritage. In America, once a person has been accepted into white society, it requires a considerable amount of African genetic input, along with other factors involving economics and relationships, for a person to fall from grace, as it were, from whiteness to blackness.
In this 1896 illustration by Ernst Haeckel (1834-1919), “Man” is precariously at the top of a tree encompassing all life on earth.
The grade has always been uphill, on the other hand, for black people to be accepted into American society, always predominantly white, no matter how much they were genetically European. Initial branding of blackness meant staying black in the eyes of white society until extraordinary circumstances or subterfuge intervened. In all this, what the majority of people, black and white, seemed to have missed was that racial differences were minuscule, along the lines of one half of one percent of the genetics every human being shares. Race itself is an artificial concept, a social construct, rather than a real biological divider.
It’s all in the mind, and those who would reinforce race as a divider of the human species have to perform mental and ethical gymnastics to justify their beliefs since science won’t do it for them. The idea that DNA test results with some percentage of African ancestry are showing merely what goes back millions of years for all of humanity also does not hold up. Yes, everyone on earth does have common ancestors in Africa, but that is not what the makers of DNA home test kits design them to illustrate, since they typically only research genetic relations going back several centuries, that being within the time frame for which they have reliably detailed information on background in their databases.
The immigration scene of young Vito Corleone, played by Oreste Baldini, in Francis Ford Coppola’s 1974 film The Godfather: Part II. Unlike Vito Corleone when he matured, the majority of immigrants, then as now, do not end up engaged in dangerous and unlawful activities, despite what rabble rousing politicians want everyone to believe.
There also appears to be an assumption among even open-minded white people that since Africa is the cradle of all humanity, then Africans themselves must be genetically closer to that cradle than the rest who emigrated to far continents. African ancestry noted in the DNA test results must, they reason, be hearkening back to long ago ancestors white people share with everyone on earth. No. The test results show genetic input from recent African ancestors. And those recent African ancestors have evolved along with everyone else on earth, including Europeans, triggered by similar environmental and social changes pushing them to adapt. The European discoverers should not be so quick to flatter themselves with ideas of inherent superiority that they lose sight of how other societies have adapted quite well under unique circumstances without prizing discovery and conquest above all else as the sine qua non of human existence.

The word “natural” on packaged foods does not mean much anymore since there are no standards to uphold it, unlike the case with “organic” on a label, but one area where consumers have been paying attention and making their preference known over the past 20 years is in the labeling of vanilla extract. A significant enough number of consumers have come to prefer vanilla extracted from real, natural vanilla pods that agribusinesses like Nestlé have switched from synthetic to natural vanilla. Synthetic vanilla is a chemistry laboratory product isolated from compounds in wood pulp or petroleum, and for decades in the latter half of the twentieth century it was the preferred choice of most consumers because it was cheap relative to natural vanilla extract, it’s flavor was at least acceptable, and for the most part consumers were not paying attention and didn’t make a distinction between the synthetically derived product and the natural one.
Food ingredient and nutrition labels provide more information to the consumer now, and more people are becoming label readers. Not all of them may know the provenance of synthetic vanilla extract, but a large segment decided they would prefer the natural stuff, and they voted with their dollars. The result was an increase in demand, something growers, the majority of them in Madagascar, were not prepared for since demand for their product had steadily dwindled for decades and they had cut back production or gotten out of the business altogether. Natural vanilla had always been an expensive spice, typically second only to saffron in price on the world market. Competition from synthetic vanilla producers had depressed prices, however, and combined with the drop in demand many farmers saw little profit in the lean decades.

The rather sudden spike in demand for natural vanilla in the past 20 years caused a scramble to reinvest in production, a process which lagged behind demand by as much as five years because of the the time and labor involved in growing and processing marketable vanilla pods. The type of vanilla most popular around the world is Vanilla planifolia, a climbing vine orchid native to Mexico and Central America. Oddly, even though the plant is native to Mexico, and Mexico continues as a big producer of natural vanilla, the place that grows the vanilla most people prefer is Madagascar, an island off the southeast coast of Africa. Soil and other environmental factors must play a role in the end result, because while the type of vanilla orchid is the same in both parts of the world, consumers express a definite preference based on variations they can detect in taste. At any rate, Madagascar currently produces up to 80% of the world’s natural vanilla.
Vanilla planifolia needs to growthree or more years before it will flower, and then each flower remains open for only one day, at which time in Madagascar it must be hand pollinated because of the lack of resident animal or insect pollinators. In Mexico, there is a species of bee that tends to the vanilla flowers. After pollination, nearly a year passes before the pods containing the seeds develop, and after that there is washing, sun curing, sorting, and other handling that goes into producing the dried black pods which have the tiny, flavorful seeds that are the ultimate object of all this careful tending. The labor intensiveness of producing natural vanilla, added to the time involved, drives its price up. It would be a mistake, though, to think individual laborers are well-paid for their work on such an expensive agricultural product; as always, it is typically the people in the middle, the traders, who reap the greatest rewards.

A year ago in March,a cyclone made landfall on Madagascar with the force of a category four hurricane. Dozens of people were killed, and it was feared damage to the vanilla crop would worsen the worldwide shortage which had driven prices up to a record $600 per kilogram (2.2 pounds) in 2017. The most recent low point in the price was 2002, when dried vanilla pods sold for $20 per kilogram. That’s the price for the agricultural product, of course, not the price after it has been further processed into the vanilla extract available to consumers at supermarkets. It turned out damage to the vanilla crop in Madagascar was not as bad as commodity brokers originally expected.

Still, for individual consumers living in cool climates outside the natural growing range of Vanilla planifolia, hedging against a volatile, expensive world market for natural vanilla, with too many of its bets placed on the crop in one place, Madagascar, hedging against all that by growing this orchid in a pot by a windowsill may be a bit of a stretch, considering the advice of some growers who say the plant needs to grow more than ten feet before it will produce flowers, and even then there’s no guarantee of getting pods that will yield recognizably tasty vanilla seeds. It might be a better bet to buy a lot when the market is low, or in other words, hoard it. Vanilla extract always contains a hefty percentage of alcohol, after all, as people who are apt to sneak a drink now and then have always known, and the alcohol is an excellent, natural preservative.

It’s not easy leaving one home for another one far off, as anyone who has ever done it can attest. If moving thousands of miles away from family and friends is difficult now, when electronic communication allows people to keep in touch, it was even more difficult in past centuries, when leaving behind familiars often meant permanent dislocation without any further contact. The emigrants, particularly if they were poor, had to be brave to make the momentous decision to leave, and then again to establish a new home.
Economics and politics are the biggest drivers of emigration, even for those leaving the United States. American government agencies don’t keep exact numbers on the amount of people leaving the country, but estimates over the past twenty years are that the number of Americans living abroad either on a temporary or permanent basis have more than doubled, from four million to nine million. People who live abroad temporarily, but longer term than tourists, are considered expatriates. The status of expatriates is usually fluid, with some eventually becoming citizens in their adopted country, and some returning to the United States.
The Emigrants’ Last Sight of Home, an 1858 painting by Richard Redgrave (1804-1888).
As hard as it is to pin down statistics on American expatriates, it seems a reasonable inference from the increasing number of articles published online and elsewhere touting overseas retirement destinations that more Americans than ever are deciding to live abroad when they have a fixed, mostly predictable income. For some of these people, the political situation in the United States may play a role in their decision, as this country more and more resembles the banana republics derided in the past, with obscene income inequality, police state tactics employed by the governing class, and the mass of people working in a condition of debt peonage. Many of the countries listed as desirable retirement destinations are in Latin America, and the reasoning among retirees may be that since the United States has come to resemble those countries politically, at least the change for them won’t be that great on that account, and their money will go further.
It’s more complicated than that, of course, because for centuries the United States interfered in the politics and economics of Latin America, which it regarded patronizingly as its back yard. Latin American countries have lately been working to disengage themselves from the most sordid aspects of American interference, with the most extreme example being Venezuela. At any rate, Latin America is popular amongst expatriate American retirees looking to get the most out of their pension dollars. Europe is generally more expensive, with the more dysfunctional economies of southern Europe offering better deals. Southern Europe also offers warmer weather and high quality health care that is on a par with the rest of Europe. American retirees are more likely, therefore, to emigrate to the sunny beaches of Spain than the frigid fjords of Norway.
Director John Huston, an American expatriate for much of his life, in a cameo appearance early in his 1948 film The Treasure of the Sierra Madre, with Humphrey Bogart. The film was about a trio of down on their luck American expatriates in Mexico. Poverty is a miserable existence anywhere, but it causes even more anxiety among those who are adrift from the support of friends, family, and familiar surroundings. The magazine articles for retirees typically mention a few destinations in southeast Asia, and hardly any spots in Africa or the rest of Asia. Presumably the heavy slant toward Latin America and Europe is because those places offer less of a culture shock to most Americans along with the aforementioned economic advantages and similar political climate. That slant also assumes the major part of the readers are of Caucasian European descent, which is not unreasonable considering American demographics, particularly of the middle class that can afford a comfortable retirement, or at least expects to do so if they can stretch their dollars overseas. Their numbers are increasing.
The propaganda in this country has long been that everyone in the world wanted to come here, and that we could pick and choose who got in. With some quibbles, that was mostly true for a long time. Now that may no longer be the case; now not as many people elsewhere may be attracted to these shores, while more people here may be looking elsewhere. For now, it is the people with dependable income, retirees among them, who are leaving. They are the brave ones, and as the political and economic situation in America swirls down a dark hole, and despite the ever more shrill propaganda about how everything is great, just great, more will surely follow to make their home elsewhere.

Sugar can be derived from numerous plants, including beets, corn, and the fruit of trees, but it has come into its own since the Middle Ages in Europe as the refined product of the sugarcane plant, a perennial grass. The plant originated in New Guinea, and from there traders introduced to Asia, where it eventually found its way to southern Europe by way of Arab merchants. As noted from its origin, the plant grows in tropical or sub tropical climates. Europeans quickly developed a taste for refined sugar, but since the plant would not grow well in Europe or northern Africa, they needed to find either another source or another place to grow, or forever be at the mercy of Arab merchants, who kept the price high.
When European explorers stumbled upon the New World in their search for a trade route to the Far East that bypassed Arab middlemen, they were interested in exploiting sugar resources as much as spices. The tropical and sub tropical bands of the New World – the Caribbean, much of eastern South America, Central America, and the far southeastern portion of North America – turned out to be well suited for raising sugarcane. The problem was finding a suitably cheap labor source for the backbreaking and dangerous labor involved in sugarcane cultivation as well as refinement. The Europeans, after exhausting the Native Americans as a labor source, turned to Africa as a source of slave labor.
There were other plantation crops that Europeans raised in the New World exploiting slave labor, such as tobacco (a plant native to the western hemisphere) and cotton, but sugar was the big money maker for them, the linchpin of Atlantic trade from the 1500s well into the 1800s. Sugar grown on plantations in the New World traveled, some in the form of rum, to northeastern ports of North America and then on to Europe, where it was traded for manufactured goods; some of the manufactured goods then were traded in Africa for slaves, who were loaded onto ships destined for plantations in the New World, their voyage across the Atlantic being known as the Middle Passage of this triangle of trade. Some didn’t survive the voyage, and of the ones who did, many suffered abominably under harsh conditions in the sugar growing regions and elsewhere.

Hundreds of years later, sugar is still exacting a toll from poor black people, as well as poor and working class people generally. The European quest for cheap sugar succeeded all too well. Now it’s found in far too many supermarket foods and beverages, where in the case of processed foods it masks the loss of wholesome flavors. Sugary beverages like soda and many fruit drinks are especially egregious sources of the endocrine disrupting carbohydrates present in refined sugar that can lead to obesity and type 2 diabetes. These processed foods are easy to prepare and are relatively cheap and, because of the sugar in them, to some people they taste good enough.
“Big Rock Candy Mountain”, first recorded by Harry McClintock in 1928, is about a hobo’s idea of paradise. McClintock claimed to have written the song in 1895, based on tales from his youth hoboing through the United States. McClintock’s 1928 recording was used by Ethan and Joel Coen at the beginning of their 2000 film, O Brother, Where Art Thou?.
People could cut back their consumption of processed foods, and certainly they could drop sugary sodas and fruit drinks out of their diet and not lose any essential nutrients. People can use will power and self control, even though there is evidence that sugar’s effects on their health are more insidious than industry mouthpieces would have everyone believe. People can do all those things. But they don’t. Why not?
What if crack cocaine were as cheap as sugar? How about cigarettes? Opioids? What levels of consumption would we encounter then among the general population, and among the poor and working classes specifically? All those substances stimulate pleasure centers in the human brain, just like a good hit of sugar does in a smaller way, and all are ultimately destructive in high enough doses. Is sugar as destructive as those other addictive substances? No, not in the short term, and it would be ridiculous to equate a cookie with a hit of cocaine. In the long run, however, over the course of ten, twenty, or thirty years, sugar consumption at modern American levels of a hundred pounds or more per person per year is proving destructive enough. Time to turn some of that exhausted soil in the tropics over from growing monocultures of sugarcane for export to growing fruits and vegetables the locals could consume for themselves. We could easily cut back from two or three lumps of sugar to just one.

January 28 is the Chinese New Year, which this time is the Year of the Rooster. The Chinese celebrations include an acknowledgement of America’s current influence on their culture, and in reply the Supreme Leader no doubt will wish “Good Luck” to all our Chinese friends, perhaps with a tweet or a cluck. Moving from the ridiculous to the sublime, we look back on Ernest Henry “Chinese” Wilson (1876-1930) and his accomplishments in bringing hundreds of Chinese plant varieties to Westerners in the early years of the Twentieth Century.
“Chinese” Wilson was English by birth, and he started out on his plant collecting in China on behalf of the English firm of James Veitch & Sons, who primarily sent him to retrieve the Dove Tree, Davidia involucrata. Wilson made numerous trips to China, Japan, and other Eastern, African, and Latin American locales over the first twenty years of the Twentieth Century, eventually collecting plants on behalf of the Arnold Arboretum in Boston. In 1930, he and his wife died in an automobile accident in Worcester, outside of Boston.

Wilson sent back to the West a staggering number of plant species, many of which, like Camellia, Magnolia, Azalea, and Crepe Myrtle, while not entirely unknown here before his collection efforts, have become so common since he gathered their multiple varieties that Westerners could be forgiven for thinking they have always been here. Wilson himself was most proud of his discovery in 1907 of the Regal Lily, Lilium regale, on an expedition to the Min River valley in western Sichuan Province, where he paid the high cost of having his right leg broken in two places in a rock slide. He made it out of the wilds safely in three days and recovered, but ever after he walked with a limp.
This New Year of the Roosterit does us good to remember a good man, “Chinese” Wilson, and his positive contributions to the Western world borne of his expeditions to China and the Far East. It’s better still to think of how the Chinese reservoir of plant diversity has enriched our own gardens. And it’s best of all to realize in these difficult times that the influence of Wilson’s good work will over the long run outweigh the tribulations visited upon us by one petulant, puffed-up rooster of a man. The General Tso’s Chicken is good; let’s enjoy that and leave aside for now it’s American variant, Orange Chicken.
