Plant of the Year 2014: Dactylorhiza × grandis

Dactylorhiza ×grandis from Blackthorn Nursery, in the garden border June 2014.

 My Plant of the Year 2014 is the hybrid marsh orchid, Dactylorhiza ×grandis, which impressed me this year in many places, wild and cultivated, during its flowering season of May and June. Typically a robust plant with big spikes of deep pink to purplish flowers, it can be an excellent garden plant whether grown in the border, as the clump illustrated above is, or naturalized in a meadow situation.

Dactylorhiza ×grandis is a hybrid between the Southern Marsh Orchid  (D. praetermissa) and the Common Spotted Orchid (D. fuchsii) and is usually present where they grow together. The name is applicable to any derivative of the cross and as plants have some fertility, and almost certainly backcross to either of the parents, a swarm of intermediates can develop within a population, making interpretation challenging at times. To help decipher it, here are pure examples of the parents, and then some hybrids.

Dactylorhiza praetermissa, showing the typically wedge-shaped lips with a central band of spots/. The flowers are usually a deep purple (this is a pale example) and contribute rich colours to the hybrid.  The leaves usually lack spots. (Yorkshire Arboretum June 2013)

Dactylorhiza fuchsii is much paler in colour, with a strongly three-lobed lip decorated by dark lines and loops. Leaves are usually spotted. (Wharram Quarry June 2014)

A swarm of parents and hybrids: the very dark spikes are D. praetermissa, pale ones D. fuchsii with intermediate hybrids in darker pink (e.g. fourth from left along the lower edge of the image). (Roadside verge A166, E. Yorks, June 2014)

A ×grandis that is close to D. praetermissa, with only slightly lobed lips, but with a more elaborate pattern of dots and dashes. (Yorkshire Arboretum June 2014)

A very robust hybrid with well-developed lip markings but also less lobing than in D. fuchsii.

A good dark-flowered hybrid, with attractively spotted leaves, and an obliging clumping habit. (A166 verge, June 2014)

 D. ×grandis growing in the meadow at The Garden House, Devon, surrounded by classic meadow plants (late May 2014).

Both parents, and the hybrid, are available from specialist nurseries and are well worth acquiring and planting close together; if conditions are right a swarm of hybrids is bound to result.

No hybrids, just a wonderful stand of Dactylorhiza fuchsii at Chatsworth, June 2014.

Bean Online

The home page of 'Bean Online', showing one of several banner images (Ray Wood in  this case).

Before this year comes to an end I must post about a project that has taken up a good deal of my time in the past couple of years - 'Bean Online'.

For the past century - the first edition appeared in two volumes in 1914 - the encyclopaedic WJ Bean's Trees and Shrubs Hardy in the British Isles has been an essential reference for anyone interested in woody plants. The four fat volumes of the eighth edition, plus their Supplement, crouch upon the shelves of many gardeners and are usually dog-eared from much use.

My set of 'Bean', with other essentials.

William Jackson Bean was born in 1863 in Malton (my nearest town - note to self, find his birthplace in 2015) but spent most of his working life at Kew, becoming Head of the Arboretum and ultimately Curator. During this period the flora of China was pouring into western gardens thanks to the efforts of the great plant-hunters; Bean got to know it all as it came in and grew to maturity. In consequence his text has a firsthand authority to it, and it has always been regarded as very 'readable'. He died in 1947 and the seventh and eighth editions were prepared by teams of contemporary experts - but to everyone the work is still 'Bean'.

Unfortunately, the eighth edition, edited largely by Desmond Clarke, who also prepared the supplement, went out of print a few years ago and a complete set has become very expensive (I'm astonished to see online this evening that a five volume set can be had for only £195 via Abebooks). It was in this context that, about three years ago, Hugh Johnson asked the publisher for John Murray (now Hachette), Tim Hely-Hutchinson, if there were any plans to reprint Bean. Not surprisingly, the answer was no, but the offer to hand over the copyright that followed was astonishing. To cut a long story short, the publisher's interest in the copyright was passed to the International Dendrology Society, and a quest was started to find the copyright holders from the Bean and Clarke families. They were eventually tracked down through a combination of detective work and good luck, and, even more fortunately, all agreed to give the IDS permission to reproduce the work. The project was taken on by a subcommittee of the IDS Scientific and Education Committee, with support from the Dendrology Charitable Company.

From the start it was Hugh's intention to make the text of Bean available online, but the question was how? The services of Bill Hemsley, a specialist in online publishing who works with Hugh on his wine books, were called in and options were discussed. A set of Bean was sacrificed to a scanner, which ran through the 4000 pages in no time, and produced an active version of the text through the magic of optical character recognition (OCR). Although this was not a perfect rendition it was remarkably good, and a team of specialist proof-readers in India tidied-up the errors. Bill organised the text into discrete entries, and devised the website functions that make it work as a searchable site.

It all took longer than hoped for, but after internal trials the site was launched a few days before Christmas and can be found at www.beanstreesandshrubs.org  It presents the whole text of the eighth edition in easily searchable format (see below), but it is the original text only, with no amendments, so it is inevitably somewhat dated. We considered making changes but decided that at this stage we should publish only the text as it is, while reserving the option of upgrading it in future. One amendment is to link the names used by Bean to the online reference The Plant List from Missouri and Kew, which brings in modern nomenclature where there has been a change in the past forty plus years and thus makes it accessible to modern users.

We very much hope that this will be a popular resource, used by as many people as possible. No doubt there will be times when we reach for a comfortable fat volume, but Bean Online is available anywhere with an internet signal - on your phone or iPad, which is a lot more convenient than lugging around the books! We hope to start work on a upgrade before too long, but a lot of fundraising is needed first.

The search or browse facilities are very easy to use, bringing up lists of names by genus, each hyperlinked to its entry. Bean names are on the left, with currently accepted names from the Plant List on the right.

Peacock project 2014

Peachicks at about ten days old: the one on the left was assumed to be female, and the other two males (brothers) almost from hatching

I have always had 'a bit of a thing' about peacocks, as may have been apparent from previous entries, but I've never previously had a chance to do anything but admire from afar. This summer, though, having hatched a couple of clutches of Lady Amherst's Pheasant eggs and feeling confident in the incubator, I decided to have a go at raising some. In season there is an extensive trade in poultry eggs on Ebay, so I bid for and won two clutches of three eggs each, both for just over £10.00. The eggs were set in the incubator on 18 June - images tell the rest of the story.

Incubation time for pea-eggs is 27-28 days: the eggs started pipping on 15 July.

By next morning three chicks were out. The others did not hatch, but the chicks were fully formed. I have no idea why they didn't emerge.

After a day or so in the incubator the chicks were transferred to a cardboard box with a brooder to act as surrogate mother. They were tame and confident from the start, quite unlike the pheasants.

Growing poults perched on the by-then redundant brooder, after about 6 weeks.

The young peafowl were transferred to a spacious shed at the arboretum at the end of August, where they lived with an earlier brood of pheasant poults. Growth was very rapid, and the first coloured feathers appeared on their necks in September.

In October arboretum staff and volunteers created a large pen for the peafowl, pheasants and a flock of 10 guineafowl I acquired at the Malton poultry auction... The peafowl and guineafowl will be allowed to roam free in the grounds once spring comes. All being well the males should moult into full colours next summer, but it takes three years for the full train to develop. They love ripping into a cabbage. Picture taken 24 December, showing the two males to the left and the back of the peahen.

Unintended consequences of a blog post.

The fantasy flowers from the National Gallery's Virgin of the Rocks

In January 2012 I wrote about a visit to the great exhibition Leonardo da Vinci, Painter at the Court of Milan, at the National Gallery, and commented on the differences in the plants portrayed in two versions of the Virgin of the Rocks - the post can be read here. Life moved on, and I gave no more thought to the subject until a few weeks ago when I received a call from Dalya Alberge, a journalist writing for The Guardian, who started her conversation with 'I believe you're an expert on Leonardo da Vinci...' I was about to say she had the wrong number when she mentioned this blog.

It seems that in a new book, Tweeting Da Vinci, the American geologist and Renaissance scholar Ann Pizzorusso, advances the case that the London Virgin is a derivative version of the earlier one, indisputably by Leonardo, in the Louvre. Her thesis is based mostly on the accurately observed geology of the latter. This, says Ms Pizzorusso, is typical of Leonardo's careful observation and rendition of natural phenomena, and she found support for this view in my comments on the botanical accuracy of the Louvre version against those of the London painting. I haven't seen the book, so can't quote her directly - the first I knew of it was Dalya Alberge's phone call, which necessitated getting the brain quickly into gear to answer her questions. The result of her investigations has now been published online by The Guardian in an article entitled The daffodil code: doubts revived over Leonardo’s Virgin of the Rocks in London

I very much doubt that this is the last word on the attribution of this painting, but I will leave that to genuine Leonardo experts to debate.
