Speaking Specifically

 



Picea glauca 'Pendula'







Ginkgo biloba 'Chi Chi'

Ginkgo biloba 'Chi Chi'

Ailuropoda melanoleuca


Acer shirasawanum 'Autumn Moon'
Because of my obsession with plants, my two youngest girls are ahead of the curve with botanic classification. They know that Acer shirasawanum 'Autumn Moon' – Saya's favorite – is commonly called a Japanese maple, but they're also familiar with the binomial nomenclature system that was first advanced by Linnaeus. Due to the plant labels around our home, combined with young children's curious minds and active brains, Harumi was spouting "Picea glauca 'Pendula', Ginkgo biloba 'Chi Chi'" etc. at age two.* They were delighted to learn that animals – from ants to elephants – are classified the same way. For example, the "Giant Panda" is known in China as daxiongmao, or "big bear cat," but scientifically as Ailuropoda melanoleuca, literally meaning "black and white cat-foot."

*My three older children were certain that I had brainwashed her.










Sequoiadendron giganteum

Chief Sequoyah
Sir Arthur Wellesley, First Duke of Wellington

































Many botanic species names can be fascinating, as they reveal something interesting about the discoverer, or the botanist, or the location of the species, or something about the plant and so on. The origin of the word species is from Latin specere, meaning "to look," then it evolved to mean "a particular sort, kind or type." Sequoiadendron giganteum – the "giant redwood" – was given its specific name for obvious reasons. Why the genus name was selected, honoring a Cherokee chief who invented an alphabet for his people, a man who never ever saw a giant redwood, is more of a mystery. The British are still irked that Wellingtonia lost out due to the trivial detail that the name had already been used for another plant, but they still commonly call it Wellingtonia anyway. Even in The Hillier Manual of Trees and Shrubs, a sentence in the Sequoiadendron description contains wellingtonia, oddly with a lower-case w.

Abies cephalonica 'Meyer's Dwarf'


Abies cephalonica is the "Greek Fir" and was named for Kefalonia, the largest of the Ionian Islands off of western Greece. At the top of the island's tallest mountain – Mount Ainos at 1628 m (5,341 ft.) – is a natural park with Abies cephalonica, but it is also distributed throughout Greece, and I saw it years ago on Mount Olympus. Cephalonica is related to Abies bornmuelleriana and Abies equi-trojani, the latter known as the "Trojan Fir" from which the Trojan Horse was constructed. The botanist who named cephalonica was the Scotsman John Claudius Loudon (1783-1843), who was also a garden designer. Unfortunately Louden was afflicted by rheumatism and arthritis, and then he had is right shoulder amputated due to a botched operation to fix his broken arm and had to learn to write with the left hand. Later he had to cure himself of an opium addiction which he developed to endure his pains.

Rhododendron exasperatum





















Rhododendron exasperatum


Some plant people still believe the untruth about the naming of Rhododendron exasperatum, that botanists were exasperated with their efforts to know where to place it in the Rhododendron scheme of classification. Actually it was named by Harry Tagg in 1930 for its rough-ribbed leaves. Exasperate is from the Latin verb exasperare which is based on asper for "rough." Spiritus asper is a medical term for "rough breathing."

 
























Picea orientalis

Picea orientalis


Where is the orient? I would describe it as places like Japan, Korea or China. When I began my career I assumed that Picea orientalis was from one of these countries, but I later read that it comes from the Caucasus Mountains of southern Russia and in northeastern Turkey. At one point for Europeans that was way east, the place where the sun rises. Orior is Latin for "rise," and later oriens meant "east." "It's all relative," Einstein used to say, noting that the Chinese considered their land to be at the center of earth's surface. The term opposite of orient is occident, from Latin occido, "to fall" or "set." Thuja occidentalis occurs in eastern North America, so it's not west for me, but it is a western tree if compared with Thuja orientalis from Japan and China. On the other hand, I fly west when travelling to Japan, to the Land of the Rising Sun, to the Far East. On the one hand is a thumb, four fingers and a pencil.

Picea orientalis 'Aureospicata'

Picea orientalis 'Aureospicata'


Picea orientalis is a favorite species for me, though I've never seen it in the wild. We grow a number of cultivars, from tiny dwarves to large uprights. My first cultivar was 'Aureospicata', and I had to drive all the way to Nanaimo on Vancouver Island to buy it from a German nurseryman. I still have it in the original Display Garden and it is now over 40 feet tall. This old-timer cones prolifically, and scattered throughout the garden are seedlings, some green, some golden and some, like 'Aureospicata', with butter-yellow new growth, later evolving to green. We are trialing one we have named 'Lemon Drop' which appears to be more dwarf; but time will tell for we propagate by grafting onto vigorous Picea abies, the "Norway Spruce." Don't take me to task for naming a plant that is not fully tested, because I do it all the time. We have to call it something, and code names or numbers are not as easy to deal with. Besides, I might give one to a plant friend to try even before we're ready for general release.

























Picea orientalis 'Sulphur Flush'

Picea orientalis 'Tom Thumb'

Picea orientalis 'Tom Thumb'


And that's what happened with Picea orientalis 'Skylands'. This golden cultivar was found at Skylands Farm in New Jersey in the 1950's. But then it was also marketed as 'Aurea Compacta' by nurseries apparently enamored with Latin. We also grow Picea orientalis 'Sulphur Flush' which is the same as 'Silver Seedling', but which name is correct? Picea orientalis 'Tom Thumb' is a golden miniature, a cute little bun, but it is also marketed as 'Tom Thumb Gold'. Again which? 'Tom Thumb', with or without the Gold, was discovered as a witch's broom on a 'Skylands', also in New Jersey. It was originally propagated by John Verkade who named it 'Compacta Aurea Tom Thumb' which is as invalid as you can get.

Picea pungens 'Hoopsii'
Picea pungens 'Globosa'


























I have cut scions and grafted many thousands of Picea pungens, so I know the species well. I wondered why the species got its name, for it doesn't have a particularly strong smell, not like Viburnum foetida or Passiflora foetida. (foetida is from Latin foetidus, and in France one name is merde du Diable, or "Devil's faeces"). Back to the pungens "Colorado Spruce," the species name is derived from Latin pungere which refers to the sharp-pricking needles, not the smell. The root is similar to Latin pugnus for "fist" (in Greek pygme) and pugnar "to fight." I've had a pugnacious relationship with the Picea pungens cultivars for years, as I never wear gloves when I cut scions or graft. Back in the old days I would cut hundreds of Picea pungens 'Hoopsii' or 'Globosa' and my hands would be pricked to red.

Acer shirasawanum


Gen ichi Koidzumi (1883-1953) was a Japanese botanist who researched Acers, among other plants. He is the one who coined the shirasawanum name in honor of Homi Shirasawa (1868-1947). Sometimes Homi is referred to as Yasuyoshi Shirasawa, but I don't have an explanation for that. In any case Shirasawa worked under Tomitaro Makino, the Father of Japanese Botany. According to Antoine Le Hardy De Beaulieu in An Illustrated Guide to Maples, the epithet is from shirasawanus and then to shirasawanum. According to my research, there are three genders that a Latin name can belong to: masculine, feminine and neuter. There are exceptions to the rule, but generic names ending in us are usually masculine, while names ending in um are usually neuter. I don't know if this rule-of-thumb applies to specific names as well, or how it has anything to do with Shirasawa's maple. I invite a smarty-pants to respond and set me straight, for I am rather dim when it comes to botanical matters.

Daphne cneorum 'Exima'

Daphne cneorum 'Alba'

Daphne cneorum 'Ruby Glow'


Cneorum is an odd species name – as in Daphne cneorum (the rose Daphne) – since it is saddled with its silent "c."* It is from cneoron, the Greek name for Daphne gnidium, a poisonous evergreen shrub with green foliage and white flowers. D. cneorum is low, compact and more cute than D. gnidium – in my opinion – and is native to the mountains of central and southern Europe. We don't propagate the cultivars anymore; I threw in the towel as they can be touchy in pots, and my irrigation crew tended to drown the plants. At least we still have some nice specimens in the garden.

*There are some who think it is properly pronounced as suh-nor-um. Perhaps a Greek scholar could weigh in.

Apollo and Daphne


Daphne means "laurel" in Greek, and in myth she was a nymph who was turned into a laurel tree by her father, to save her from being ravaged by Apollo. I may do the same with my young daughters.

Daphne bholua

Daphne bholua paper making

Daphne bholua paper making

Daphne bholua paper making


Daphne bholua – pronounced bo-lu-a* is a Himalayan species, and it has special meaning for me as I have seen it in the wild. Back when I was sturdy and vigorous I was on a trek in the Mt. Makalu (5th highest mountain in the world) area. Overtaking us on the trail were dozens of porters with their heavy awkward loads of bholua tied to their backs. Later we caught up with them near the village processing center. The common name for D. bholua is "Paper Daphne," and that is exactly what was being manufactured. All important documents, such as marriage contracts, property deeds etc. are on the Daphne paper. Back in the capital of Kathmandu I purchased a few sheets as a souvenir at the stationers shop. The owner probably had no clue where I had just come from and why I wanted the more expensive Daphne paper.

*The origin of the name bholua is the Nepalese name for the plant, bhulu-swa.

Beta vulgaris ssp. cicla

Pulsatilla vulgaris 'Rubra'





Pulsatilla vulgaris 'Alba'


















There are a number of plants with the specific name of vulgaris, such as Beta vulgaris ssp. cicla (Swiss chard), Calluna vulgaris 'Robert Chapman' (Robert Chapman heather) and Pulsatilla vulgaris 'Alba' (white Pasque flower), and none of these plants are vulgar at all. Vulgaris is derived from Latin vulgus for common, ordinary people, and I guess that at times the common people can be quite indecent, coarse or obscene. Medically you can be afflicted with Acne (another Greek word) vulgaris, Verruca vulgaris (warts), and other skin diseases like Vitiligo vulgaris where patches of skin can lose its pigmentation.


























Mahonia aquifolium

Flag of Mexico


A little hobby I have is to ask plantspeople what the specific name aquifolium is referring to, as in Mahonia aquifolium. Invariably they respond that the foliage has a "wet" look. That's what I used to assume as well, but actually it refers to the spiny barbs on the leaves. One could say that these barbs resemble an eagle's beak, and in Spanish the word for eagle is aquila. The Mexican flag contains a vertical tricolor of green, white and red. In the center is the national coat of arms, and an eagle is holding a serpent in its talons. The eagle is perched atop a prickly-pear cactus, and that atop a rock in a lake. All due to an Aztec legend that their Gods told them to build a city where an eagle was eating a serpent, and now it is the present-day site of Mexico City. What is confusing is that aqui or aqua is Latin for water. Aqui also means here in Spanish, as in Estoy aqui, or "I am here." Some botanists insist that Mahonia aquifolium, the "Oregon Grape," should be Berberis aquifolium, and it's true that this plant is in the Berberidaceae family. In any case Mahonia was named by Thomas Nuttall for plant nursery owner and friend Bernard McMahon in 1818. McMahon (1775-1816) is credited with publishing America's first seed catalog. He was also a friend of Thomas Jefferson, and some of the Lewis and Clark Expedition planning was done in his home, and upon the expedition's return, McMahon germinated and distributed plants from the trip.

























Sisyrinchium douglasii


Fritillaria pudica


Venus pudica
Many visitors to Oregon probably restrict themselves to Portland and the Willamette Valley where the grass and trees are green, but the bulk of Oregon – to the east of the Cascade Mountains – is a far different country. The Douglas Fir and Western Hemlocks give way to Ponderosa Pine, and at Kathryn Creek on the Washington side is a nature reserve that I like to visit at least once a year. Every season is different, but if you arrive at the right time (usually mid-March) you will see the "Douglas Blue Eye Grass," Sisyrinchium douglasii, and if you keep a sharp eye you may even stumble onto a white-flowered form. Of course, the species honors David Douglas, the famous Scottish plantsman. You might also find a wildflower more rare than the Blue Eye Grass, Fritillaria pudica growing on steep slopes. This charming sweetheart in the Liliaceae family features butter-yellow flowers on nodding stems. You have to stoop and lift up the flowers to see inside this low-growing bulb. Pudica is the feminine form of pudico which means "modest," and in western art it is a classic pose – the Venus pudica – where one hand covers the woman's private parts. Men are not depicted as so modest, although the member size can vary greatly.








Lilium martagon 'Claude Shride'


Some other species names that I find interesting: Lilium martagon is the "Turk's Cap Lily," coming from a Turkish word meaning "cap" or "turban" due to the reflexed petals.

Myrteola nummularifolia


Myrteola nummularifolia – the specific name means "like a coin" (Latin nummus), and nummulus is diminutive of nummus.

Quercus robur 'Butterbee'


Quercus robur was named for its reddish hardwood, from Latin ruber for "red."

Punica granatum 'State Fair'


Punica granatum (Pomegranate) is from Latin granum for "grain" or "seed," and granatus "having many seeds."

























Quercus suber


Quercus suber is the Latin name for the outer-bark of the "Cork-Oak," from the Greek syphar for wrinkled skin.

Rhododendron clementinae


Rhododendron clementinae was named for the Scottish plant explorer George Forrest's wife, Clementina Traill.

By the way, I occasionally refer to the botanical family that a genus belongs to, as in Berberidaceae for the Mahonia genus. These families are not a part of the binomial system of nomenclature, but are groups of genera, and their names occur by adding the suffix aceae to a name of a genus of that family. But keep in mind that the botanical classification of plants is never finished, never absolute, but is an ongoing process that merely reveals our current understanding of a plant.

Plant is Latin planta for "sprout" or "cutting," and then went into Old English plante for a young tree or shrub newly planted, or an herb newly planted.

I don't want to come across as a plant policeman, or as a nomenclatural Nazi, but rather as an aficionado of plant names. Nomen is German for "name," and after all I am of Germanic origin, so nomenclature is my particular lingua.*

Thanks for the Memories

Berberis thunbergii 'Bagatelle'


Now
I miss more people than I currently know;
That’s what happens when you get old.

The same could be said about many plants I have grown, that I have discontinued more taxa in my career than I currently grow. Good riddance to some, my crew would say, such as the Berberis genus that caused groans when a barberry thorn would embed itself into the tip of their thumbs, later to infect. We would also top graft the dwarf B. thunbergii 'Bagatelle' onto a single stem of the vigorous upright B.t. 'Helmond Pillar'. Probably no other wholesale nursery in the history of horticulture has attempted such folly, but our crop was of a common plant, but one produced differently, which allowed us to compete with the large wholesale nurseries that grow millions from rooted cuttings. Einstein once said, "Imagination is more important than intelligence."


Berberis temolaica


Berberis temolaica


Most garden retailers in America only know the Berberis thunbergii species, primarily due to its deep red summer foliage which evolves to dazzling crimson in autumn. But there are dozens of other species or hybrids that are worthy of growing, even though they are not well known. Berberis temolaica is a rambunctious species that features powder-blue stems and leaves. Coming from the arid environment of southeast Tibet it prefers a sparse soil with sharp drainage, not necessarily the lush, well-irrigated conditions at Buchholz Nursery. Still, I have one happy specimen in the ground at Flora Farm, and we might bring it back into production in the future. The species was first collected by Frank Kingdon-Ward in 1924 and it received the Royal Horticultural Society's Award of Garden Merit. The specific epithet temolaica is due to its discovery on the Temo La (Pass) in the Tibetan province of Pome, although it was also distributed as B. mekonensis when first introduced.


Berberis darwinii


Berberis darwinii


Charles Darwin


Berberis darwinii, with its yellowish orange flowers abundantly borne, makes a dramatic statement in the spring garden. The thorny shrub is evergreen, unlike many other barberries, so foliage lacks the autumn appeal of the deciduous species. Frankly, we discontinued with B. darwinii because of: 1) poor sales and 2) it is invasive in certain USA states such as California and countries like New Zealand. But, I've seen the species in a few gardens besides my own and it didn't appear to be overly thuggish or spreading. B. darwinii is native to southern Chile and Argentea and was discovered by Charles Darwin (1835) during the voyage of the Beagle. Despite its reputation for invasivity, the RHS gave the species its Award of Garden Merit.


Berberis linearifolia 'Orange King'


Berberis linearifolia is another evergreen shrub from Chile. I have never encountered the straight species, only the cultivar 'Orange King', where the spring flowers are most vividly orange. It's a strange color, really, perhaps a little too gaudy for the discerning gardener. But it was fun when our crop was in bloom in the middle of the greenhouse, and our late-March visitors would hurry past all the other plants to see what the fiery glow was all about. The flowers are larger than with B. darwinii, and the leaves – gray-green with silvery undersides – are also more attractive in my opinion, but then I'm a fan of the skinny. I don't collect plants for myself anymore, although I do so for the new nursery owners, so maybe we'll bring back 'Orange King' into production. A sister B. linearifolia is 'Jewel' which I have not seen, but The Hillier Manual of Trees and Shrubs (2019) indicates: "Flowers scarlet in bud opening to bright orange." That would be fun to see, but Hillier threw me a curve by listing B. linearifolia as the old name for what should now be called B. trigona (three-angled).


Berberis 'Red Jewel'


Berberis 'Red Jewel'


Berberis 'Red Jewel'


E.H. Wilson


I collected the hybrid Berberis 'Red Jewel' many years ago under the botanic name of B. x hybridogagnepainii 'Red Jewel'. The gagnepainii species is native to Sichuan, China and was introduced by E.H. Wilson in 1904 while collecting for the Veitch Nursery firm in England. We discontinued with it a dozen years ago although a couple of 7' tall and wide specimens remain in the landscape which are about 25 years old. In the trade it is often listed as B. x media, but RBG Kew's Plants of the World Online sticks with the x hybridogagnepainii and suggests its cross is B. candidula x gagnepainii. Stunning in the early winter landscape, 'Red Jewel' looks like a vigorous B. thunbergii cultivar to me, but maybe its mature size is why it never garnered much favor for Buchholz Nursery sales. As I alluded at the beginning, the employees are happy about that.


Berberis jamesiana



Berberis jamesiana


"James' barberry," Berberis jamesiana, is a deciduous shrub with a vigorous, upright, bushy habit. Native to China and Tibet – but only hardy to 10F, USDA zone 8 – it was introduced by George Forrest in 1913. Drooping, spring flower clusters are a cheerful light-yellow. Oblong fruits with a pale-white color develop in summer, then they evolve to salmon-red in autumn, then to deep-red at the onset of winter. I like to pop a ripe berry in my mouth; I don't really eat it, instead I nibble out the tart juice then spit out the pulp.

Berberis nevinii


Berberis nevinii


I collected Berberis nevinii years ago, a southern California evergreen native that Hillier and others classify as a Mahonia. Taxonomists debate the two genera in the Berberidaceae family with some suggesting that all Mahonias are actually Berberis. In any case, the "Nevin's barberry" features small, narrow blue-gray leaves and tiny berries that ripen to red. According to Calscape (California Native Plant Society) it is "cold hardy and heat tolerant," and a solo specimen at Flora Farm has experienced both extremes. We used to root the species from summer cuttings under mist, but there wasn't much demand so we discontinued about 20 years ago. I was surprised that Calscape claims it is a "federally and state listed endangered species with about 500 individuals remaining," but nevertheless "it is widely cultivated in gardens and parks." It was first described by American botanist Asa Gray in 1895 and named for a fellow botanist, Reverend Joseph Cook Nevin (1835-1912).

Helen Ganderton - EH Wilson's Wife


Berberis wilsoniae


Berberis wilsoniae is a deciduous shrub from Yunnan, China, originally introduced by E.H. “Chinese Wilson” in 1904 and named for his wife.* We propagated the cultivar 'Ace' for a number of years, but discontinued when our original stock plant perished in a near-zero Arctic freeze. The propagating crew was not at all sorry to have it gone. But it showed off in spring with numerous yellow flowers which pleased the bees, and then was followed by attractive red berries. The summer foliage color was an interesting reddish blue-green that transformed to brilliant orange-red in autumn, and the fall color persisted well into winter. I'm not sure how the selection 'Ace' differs from the type because it's the only one I have grown.

*Specific epithets that end in “iae” honor females, such as Corylopsis willmottiae and Rhododendron dalhousiae. I wonder why the eminent plant-hunter Wilson would name a thorny bush for his wife when they apparently got along well with each other.

George Forrest


Berberis replicata


Berberis replicata


Berberis replicata is a Chinese species seldom encountered, but one that is championed by Oregon plant expert Roger Gossler who writes, “People always see this barberry and ask what it is and want it.” The narrow evergreen leaves are dark green above and glaucous beneath, but the real fun is the mahogany-red new growth which lasts into summer. Roger continues, “Our plant is 10 ft. tall by 9 ft. wide after 20 years. Hardy to 0 F – a really tough plant.” The species was introduced to cultivation by George Forrest in 1913.

Frank Ludlow and George Sherriff


Berberis sherriffii


A Quest of Flowers by Harold Fletcher


Berberis sherriffii is another rarely-encountered species that was introduced from Tibet by the plant-hunting team of Ludlow and Sherriff in 1938. It is renowned for drooping panicles of blue-black berries, but I don't have it anymore and can't recall the flower color (probably yellow). Major George Sherriff (1898-1967) was awarded the Victoria Medal of Honour for his plant introductions but Frank Ludlow, while equally qualified, refused the award out of excessive modesty. I have been fortunate to walk in their footsteps in Bhutan and the Himalaya, all prompted by Harold Fletcher's A Quest of Flowers which chronicles their discoveries.

Jean Andre Soulie


Berberis soulieana 'Claret Cascade'


Berberis soulieana 'Claret Cascade'


The Long Road section of the nursery is highlighted by an impressive specimen of Berberis soulieana 'Claret Cascade', an evergreen shrub with arching branches, purple young foliage and rich yellow-orange flowers. The Chinese species honors Father Jean Andre Soulie (1858-1905), a French missionary and botanist who collected more than 7,000 species. Poor Soulie's life ended after he was captured, tortured for twelve days, then thankfully shot by murdering lamas in Sichuan during the 1905 Tibetan Revolt. The common name of 'Claret Cascade' is the “rosemary barberry” due to its similarity to Rosmarinus officinalis, and the “claret” part of the cultivar name refers to the claret-red stems, most noticeable in spring.

Berberis stenophylla 'Corallina Compacta'


Berberis stenophylla 'Corallina Compacta'


Berberis x stenophylla* is also called a rosemary barberry, and it is a hybrid of B. darwinii x B. empetrifolia. I've never grown the straight hybrid, only the dwarf cultivar 'Corallina Compacta' which grows only 12” tall and 18” wide. It features coral buds that open to orange flowers, and also for its coral-colored berries that eventually ripen to black. As with most barberries 'Corallina Compacta' prefers full sun, and it will succeed in almost any soil as long as it is well-drained. It is perfect for the rock garden or a container, attractive all months of the year.

*The hybrid name comes from the Latin word stenophyllus which means having narrow leaves.


Berberis thunbergii 'Helmond Pillar'


Helmond Castle, The Netherlands


Hillier describes Berberis thunbergii: “An invaluable small shrub, compact in growth and unsurpassed in the brilliance of its autumn foliage and bright red berries.” I totally agree with that assessment, however that doesn't necessarily mean that I should be growing it at all. Cultivars have come and gone over the years besides the 'Bagatelle' grafted onto 'Helmond Pillar' I mentioned earlier. We also top-grafted 'Gold Nugget' to nice effect...until I discovered it was ® – a restriction of the use of the trade name I assumed – so we discontinued to not run afoul of the law. As for 'Helmond Pillar', it was named for a city in southeastern Netherlands which is perhaps more famous for its 15th-century castle. The barberry starts out with a narrow pillar shape which looks good initially, but at Buchholz Nursery we find that it continues to broaden with age. Our oldest specimen is located by our front gate and is about 8' tall by 4' wide in 15 years. Since we discontinued propagation some of our other garden specimens were dug and potted up; however they didn't go entirely away since they resprouted from the roots that were left behind, and those shoots arose in an even less pillar-form.


Berberis thunbergii 'Pow Wow'


Berberis thunbergii 'Gold Pillar'


Berberis thunbergii 'Gold Pillar'


Berberis thunbergii 'Orange Rocket'


Berberis thunbergii 'Pow Wow' and 'Gold Pillar' faced the same broadening issue, with 'Pow Wow' being a total sham with the description (from Hillier) “A slender, upright, dwarf shrub...” A planting of three at Flora Farm has filled in the middle, so the entire patch is about 2' tall by 8' wide. The planting scheme was a profound failure but the new Flora Farm owners have kept them intact. I also had an 'Orange Rocket' in a container but decided not to put it into the landscape.


Carl Peter Thunberg


Thunberg's Flora Japonica


The Berberis thunbergii species honors Carl Peter Thunberg (1743-1828), a Swedish naturalist who was a student (“apostle”) of Carl Linnaeus, and he was sometimes referred to as the “Japanese Linnaeus.” He was promoted to head surgeon and gained fame helping local doctors to cure syphilis, known in Japan as the “Dutch disease.” While restricted at first, eventually Thunberg was granted access to the Japanese interior where he collected extensively, leading to two scientific works, Flora Japonica (1784) and Fauna Japonica (1833). Besides the Berberis thunbergii, other specific epithets honoring him are Allium thunbergii, Arisaema thunbergii, Spiraea thunbergii, Pinus thunbergii and others.


Berberis calliantha


Berberis tricanthophora 'Cally Rose'


Berberis tricanthophora 'Cally Rose'


The name Berberis is from Medieval Latin and refers to B. vulgaris, The “European barberry,” and is thought to have derived from barbariyya in the Berber language. I have read that there are about 400 species (Missouri Botanical Garden) and other sources suggest 600-800 species. That wide variation in the number means that taxonomists will squabble forever about the nomenclature.* I was on a barberry collecting phase in my career about 25 years ago, for despite the thorns and the fact that some species are invasive, I was still attracted to the berries and fall foliage colors. I bought three plants each of about 12 species from a retail mail-order company. We were very careful about the correct identification, but at the seller's end there was a significant mix-up. For example, two plants of one species were clearly different from the third. So, was the solo plant correctly identified, or were the other two? The company was contacted for assistance, but they shrugged it off as: “Well, you win some and you lose some,” a slap in the face of the integrity of the Flora Wonder Arboretum. As far as “losing some,” they lost me as a customer from that point on.

*The leading authority on the Berberidaceae family was British botanist Leslie Walter Ahrendt (1903-1969), known for his revision of the Berberis and Mahonia genera. I assume he kept a pair of impenetrable gloves on hands.


In an abstract from the Journal of the Linnean Society of London in May 1961, Ahrendt wrote, “The time is fast coming when gardens of any pretensions to beauty will be judged by their collections of Berberia, for there is not any other class of evergreen shrub which affords so many points for interesting observation.” Perhaps a little over the top.

If the reader hasn't yet fallen asleep and desires more barberry news, I can recommend a fun article, A Berberis Journey by Julian Harber.
