A Hemlock by any other name…

The leaves were long, the grass was green,
The hemlock-umbels tall and fair,
And in the glade a light was seen
Of stars in shadow shimmering.

[The Fellowship of the Ring, ‘A Knife in the Dark’, p. 191]

Umbellifers in Roos Graveyard, East Yorkshire, May 2014

It is the 9th of June 2014, and we have recently passed the 97th anniversary of the moment when the invalided soldier J.R.R. Tolkien was mesmerised by his young wife, Edith, dancing for him near Roos in East Yorkshire. He later acknowledged to his son, Christopher, in a letter dated 11th July 1972 that this event inspired the romantic fictional encounter between the immortal Elven Princess, Lúthien Tinúviel with the mortal hero Beren. In his correspondence to his youngest son Tolkien mentioned the location, but also that the event took place in “a small woodland glade filled with ‘hemlocks’ (or other white umbellifers).”(1)

The personal importance of this event to Tolkien can be illustrated by the number of times he reworked this meeting in both poetry and prose between 1917 and 1954. He wrote at least four different versions of the encounter, and at least two summaries in which the ‘hemlocks’ aren’t mentioned. There are doubtless other versions which have not so far been published.  In addition to the letter informing Christopher, he related the same genesis of the story to his American publishers in 1955 (2), and in a letter to Christopher Bretherton in 1965 (3). The symbolic importance to Tolkien of the woodland dance is also emphasised by that fact his own gravestone is inscribed with the name of ‘Lúthien’ under the name of Edith, and the fictional ‘Beren’ under his own name. Although the inspiration took place during World War One, it was of sufficient importance for Tolkien, more than half a century later, to insist that this event be memorialised by the addition of ‘Lúthien’ to his wife’s tombstone.

So, why was this West Midlander J.R.R. Tolkien in a remote peaceful woodland glade in East Yorkshire, while the First World War was still raging several hundred miles to the south? Tolkien enlisted in the war as soon as he had sat his University finals, and in June 1916 he was sent to France to join the rest of the Lancashire fusiliers. After involvement in the Battle of the Somme in July he contracted Trench Fever, and he returned to England in November to convalesce. Initially, Tolkien worked on his emerging mythology at Great Heywood in the Midlands, but in the spring of 1917 he was posted to the Humber Garrison in East Yorkshire. One result of Trench Fever were recurrent bouts of high temperatures and debility, and it was during these that Tolkien spent some time recuperating at Brooklands’ Officer’s Hospital in Hull through 1917 and 1918. This period of recuperation saw “Tolkien’s Mythology for England” really begin to take shape, and he first wrote about two characters, which he would later state was the most central story of his mythology. His readers first became aware of Beren and Lúthien as background figures when they were captivated by The Fellowship of the Ring (1954), but their true significance was only really appreciated when The Silmarillion was published posthumously in 1977.

Determining which particular species Tolkien was referring to when he used the word ‘hemlocks’ may help to both visualise the setting and approximately date the event, as different umbellifers flower at specific times of the year. In the official biography, which was published in the same year as The Silmarillion, Humphrey Carpenter dated these events to spring 1918, but the diligent research of John Garth has shown that spring 1917 is the correct year. According to Richard Fitter “many other umbellifers are loosely referred to as hemlock”(4), and Tolkien’s letter quoted above indicates this was precisely the case with him. Rather surprisingly the linguistically precise Tolkien was vague about this particular subject. So, was the species he saw actually Hemlock (Conium maculatum)? “Tall” is one of the most constant adjectives ascribed to hemlocks in the many versions of the fictional encounter Tolkien wrote, including the extract from the poem quoted at the head of this article. There is no doubt that Hemlock, which can exceed seven-feet in height amply fulfils that criterion. However, there are legitimate reasons for believing that the poisonous plant Hemlock is not the species, which surrounded the dancing Edith. Hemlock gives off a really unpleasant scent even before it comes into flower, sometimes likened to an infestation of mice. When Hemlock begins to flower the smell is even more intense and pungent, and there can hardly be a less romantic aroma to accompany a real-life, or fictional love story. Also, Tolkien explicitly states that the actual dance took place in a woodland glade, and this is not really the suitable habitat for a large growth of Hemlock. They are much more likely to be found in open areas not shaded by trees, such as waste ground or by roads and stream-banks.

Hemlock (Conium maculatum) – note the red stippling on stem, and the feathery-like leaves

Another possible contender for the species which Tolkien saw could be Cow Parsnip, also commonly known as Hogweed (Heracleum sphonydylium). In some respects this seems more likely than Hemlock, as it does not have an unpleasant smell, and it commonly grows in woodland. Flora Britannica notes that in June “areas of rough grassland full of the large white flower discs can seem almost luminous under the full moon.”(5) On the negative side it does not grow as tall as Hemlock, or some other umbellifers, and its larger, flatter flower discs do not cluster in such a way that fits Tolkien’s description of the flowers as like a “cloud” (6) or a “mist” (7). Phil Mathison discovered during research for his book Tolkien in East Yorkshire, that the spring of 1917 in East Yorkshire was “of an exceptional nature, brilliantly fine and warm.”(8). The spring of 2014 was similarly advanced, so it may be possible to approximately date Edith’s dance by comparing the flowering period of the relevant umbellifer species. In 2014 both Hemlock and Hogweed began to flower in the Roos area on almost exactly the 1st of June, and both should continue to flower for at least two months, and longer in the case of the Hogweed. Superficially this agrees with the earliest surviving version of the story, which states that “on a time of June they were playing there, and the white umbels of the hemlocks were like a cloud about the boles of the trees.” (6).

Hemlock (Conium maculatum) Note the red stippling on the stem & pale green "feathery" leaves
Hogweed (Heracleum sphondylium) Note the large flat “umbel” and hairy stem

Despite the explicit use of June in the first version, Tolkien complicated the spring time-frame by including additional botanical details in later versions. In The Lay of Leithian the meeting of the lovers takes place after the chestnuts had recently shed their flowering candles (9). In 2014 at the latitude of Roos the Horse Chestnuts (Aesculus hippocastanum) started to flower before the end of April, and the flowers had all been dropped by around the third week in May. This version would seem to be set earlier than June, as by then the chestnut flowers would have turned brown, and started to rot away.

A third species of umbellifer, Cow Parsley (Anthricus sylvestris) also known as Queen Anne’s Lace flowers at the correct time. According to Flora Britannica: “Cow Parsley is arguably the most important spring landscape flower in Britain. For nearly all of May, almost every country road is edged with its froth of white blooms.”(10). The froth of white blooms of Queen Anne’s Lace is the most accurate fit with Tolkien’s description of the hemlocks as being “like a cloud” or “like a mist,” and, as many of the flowers exceed six feet in height, the epithet “tall” is also fitting. John Garth’s researches in East Yorkshire led him to identify Tolkien’s ‘hemlocks’ as Queen Anne’s Lace or Cow Parsley (11), and Dinah Hazell in the Plants of Middle-earth concurs (12).

It may be possible to roughly estimate the date of Edith’s dance by comparing the flowering period of Queen Anne’s Lace at Roos in the spring of 2014 and extrapolating that back to 1917. This year the white umbels began to open in sheltered spots around the 1st of May, and by 10th of May it was a fine spectacle – it remained in this condition for most of the rest of the month. However, in Dents Garth, the supposed site of Edith’s dance in Roos, the flowering was definitely beginning to look tired and faded in most places of the woodland by 27th of May. Heavy rain both on and subsequent to that date ensured it did not survive into June. It is unlikely that Tolkien would have commented favourably on the beauty of the whiteness of the ‘hemlocks’ if it had already begun to fade, so a date in June seems rather unlikely. This would suggest that Edith Tolkien’s dance occurred during the month of May 1917, with some time after the tenth of the month being the most likely.

When Aragorn quotes the lines of verse about Beren and Lúthien given at the top of this page, it would not have been appropriate for him to have called the flower Queen Anne’s Lace. The name of a seventeenth-century English monarch would not have fitted easily either into the scansion of the poem or a narrative set in a remote past! It would have been an equally unsuitable name for events from the First Age of Middle-earth, which is placed in an even more remote millennia. The alternative name of Cow Parsley may not have been aesthetically pleasing to Tolkien for different reasons, but there are many other localised names he could have used. In various parts of the United Kingdom Cow Parsley is known as Mother Die, Step-mother, Grandpa’s Pepper, Hedge Parsley, Badman’s Oatmeal and even Rabbit Meat! Of these only Hedge Parsley seems acceptable as a possible alternative for the hemlock, which was the one he utilised. Tolkien may have been unaware when he wrote The Book of Lost Tales with its diminutive protagonists that another vernacular name for Cow Parsley is the highly appropriate Fairy Lace! Of course Tolkien may simply not have been interested in knowing the precise name used by botanists or local rural folk. He called all similar umbellifers ‘hemlocks’, and what was good enough for him was also good enough for his story of tragic lovers.

Anyone with a vaguely classical education in the late-nineteenth century would have been aware that Socrates was sentenced to death, and was poisoned by a fatal drink of hemlock. Socrates, despite the urging of his friends accepted the courts’ decision and nobly drank the fatal dose whilst still discoursing to his disciples. Hemlock is therefore associated from ancient times with a story of noble self-sacrifice, and it seems highly appropriate that Tolkien utilised the name hemlock at the very commencement of his great story of love and self-sacrifice. It seems Tolkien selected the name ‘hemlock’, either from a lack of precise botanical knowledge of the exact species he saw, or because he felt that that word fitted best within his story.

I have shown beyond reasonable doubt that Cow Parsley is the species Tolkien intended as the “great misty growth” of “white umbels…like a cloud about the boles of the trees”(6). This identification and the examination of the flowering period of the plant at Roos this spring confirms that Edith’s dance almost certainly occurred after 10th of May and before the 31st of May 1917.

Postscript:  11-06-2014: I travelled approximately 30 miles north of Roos today to Wharram Percy (near Wetwang) on the Yorkshire Wolds, and was surprised to see Cow Parsley still in flower. In fact it was in better condition than those blooms in Roos on 27th May. Roos is more or less at sea level, but Wharram Percy is approx 550 feet above sea level. It’s amazing the difference 30 miles north & a much higher location, which faces north can have on flowering times.

    Excellent blog post, thanks Michael that was a very interesting and illuminating read! 🙂

    • Michael Flowers

      Thank you. I’d visited Roos before I knew about the Tolkien connection, but I’ve been intrigued by the Beren & Luthien story & the ‘hemlocks’ for a long time. It’s satisfying to have narrowed down the date that the inspiration took place from purely natural flowering times!

    Thank you, Michael!

    I wouldn’t go as far as “beyond reasonable doubt”, but you have certainly made a strong argument, re-opening the possibility for a May dating.

    A couple of questions come to my mind.

    You say that the springs of both 1917 and 2014 were warm, which would be in comparison with surrounding years, but do you have actual meteorological data to compare these two years? A difference of just a single degree or two can make a large difference.

    Also, you mention Dent’s Garth, which is considered the most likely spot, but have you sampled other possible (though obviously less likely) spots around Roos? As you mention, local conditions even on a very small scale can also make a significant difference.

    • Michael Flowers

      Thank you Troels. I wish I had checked out the flowering dates of cow parsley last year, which was particularly cold, to see how much variation in flowering times there was compared with this year. The area of Holderness around Roos is very flat and featureless for several miles in every direction, so I believe there will be very little variation in flowering times of cow parsley in other pockets of woodland. I did check Cow Parsley in other parts of East Yorkshire this year, including 20+ miles to the west (also at sea level) and it all seemed to be at similar states of flowering. The only exception was 30 miles north & 500+ feet higher up, which was upto 10 days behind the Roos plants. There are relatively few pockets of woodland in the immediate vicinity. However, there is at least one other important candidate, which is on private land, but I hope to access some time in the near future. I’m not 100% satisfied that Dents Garth has been identified correctly as the woodland in question. This is something I was going to turn my attention to next. In the letter to CJRT Tolkien says the woodland was “at Roos”, but in the other 2 letters mentioned he says “near Roos.” As Dents Garth is actually in Roos, and JRRT was usually so precise with his choice of words, I believe “near Roos”, suggests this other candidate is worth consideration…to be contd

      • Michael Flowers

        Dents Garth is also not really large enough to include a glade! In some of the early versions of the mythology Tolkien mentions 3 species of tree, and I would like to see if any of these are at the alternative location. As far as I remember I didn’t see any of these 3 species in Dents Garth, but I am going to check it out right now!

        • TroelsForchhammer

          Thanks a lot, Michael,

          It is really good to see that you have considered the terrain so thoroughly, and I’ll look forward to seeing your progress.

          Given the thoroughness you’ve approached this with, I suspect that we’ll learn more about the flowering stats of the Cow Parsley (and the other species also?) for the coming years 🙂

          I don’t know how to make a table in the comments, but it appears that Bradford and Sheffield are the two weatherstations for which the Met Office have weather data for both 1917 and 2014 that lie closest to Roos

          A comparison for the month of May in the two years shows that there was a minor difference in minimum temperatures for the two years (7.7°C vs. 8.5°C in Sheffield and 6.6°C vs. 8.2°C in Bradford – 1917 mentioned first), as well as in rain (43 mm vs. 123.8 mm and 64.3 mm vs. 101.4 mm).

          Maximum temperatures were actually just a bit lower in 2014 than in 1917 (17.2°C vs. 16.6°C and 16.3°C vs. 15.8°C) and with slightly more sun hours in 1917 compared to 2014 (176.5 vs. 144.7 – only data available for Bradford).

          Unfortunately I couldn’t find data on average temperatures, and I have no idea how the combination of these statistics would affect the flowering times of the different umbellifers, but I thought you might be interested 🙂 (I’ll send you a spreadsheet on Facebook)

          • Michael Flowers

            Thanks very much for your feedback, and very useful data for the next draft!

  • Mike Cavanagh

    Thanks for very intriguing detective work! I’m curious as to what, if any, allowance you made for climate change factors, i.e. climate likely to be cooler then. The specific seasonal temperature differences between 1917 and 2014 where former was somewhat cooler would of themselves indicate possible later flowering. Longer term trends would also delay flowering in relation to much later years. Precipitation especially when related to temperature would also cause variations (especially as from Troel’s information 1914 was not as wet). In effect the uncertainties provide a range – confidence limits if you like – of possible initiation and end to flowering. Add to this potential ‘micro-climate’ effects and the uncertainty grows even more. Later flowering with less precipitation may have also resulted in a more profuse flowering. Just some thoughts. Many thanks again. MikeC

    Fascinating 🙂

    I wandered around Roos for a day and tried to find a suitable woodland. Of course what the tree cover was like 100 years ago may have been very different, but there is a fox covert close to Roos which seems to me to fit all requirements.

    Cow parsley is present all around Roos, and I concluded that it fitted the bill, but the fox covert was the nearest thing I could find to a glade without going on to another village.

      Hi Dave,

      My reply from 2nd June on my blog, which I thought it was worth sharing here:

      Hi Dave,

      Thank you very much for spending the time to comment.

      Dents Garth is a relatively private place. Last May a short film was made re-enacting the dance of Lúthien in that woodland. This took more than 2 hours, and not a single individual walked past the filmmakers. I have been several times over the last few years, and I’ve never seen anyone else in the woodland.

      The big question is does Fox Covert have an understory of Cow Parsley? I will check it out, if I don’t have to trespass, but if it doesn’t have any Cow Parsley it can be ruled out.

      All the various findings in an around the churchyard, seem to corroborate the identification of Dents Garth. The most upto-date version of my piece may be read here:

      Thanks again for taking the trouble to comment

      Best wishes


      Followed by a reply from 2 days later after revising Fox Covert

      Hi Dave,

      I’ve just returned from a visit to Fox Covert. When we arrived we realised that we had checked it out 5 years ago.

      The northern part is full of Willow Carr and is waterlogged, and isn’t suitable for dancing of any kind. There was a thin line of Cow Parsley around the wood, but none inside, as far as I could see.

      I walked along the eastern edge to the southern corner, and when the vegetation allowed peered in. Although the southern part was drier, I couldn’t find any evidence that any member of the umbellifer family grew inside.

      I’m afraid I have to conclude that Fox Covert is far less likely to be a suitable candidate for the site of Edith’s dance. It may be slightly more private, but it doesn’t have the variety of tree species mentioned by Tolkien in various versions of the story, and all the clues in and around the churchyard suggest Dents Garth is a much better fit. (No beech, linden, chestnut or elm, yet all of these are in Dents Garth)

      Thanks for adding your point of view, and it was interesting checking it out, but I’m afraid I haven’t seen anything this afternoon to make me change my mind.

      Best wishes

    We can never be absolutely sure where it was, unless Daeron remains there mourning to tell the tale. But I would love to reduce the odds so far that one could say with reasonable certainty that this is where a man and his wife spent time in the seeming likelihood of imminent death, with all his friends but one already dead and no idea whether the hordes of Utumno could ever be turned back. The metal monsters that inspired the original ‘Fall of Gondolin’ had all been seen, along with the spiked helmets of her defenders.

    Here JRR and Edith would return, in their old age, in their minds, when feet could no longer take them there.

    Desperate love will make Doriath of such places.

    This was where JRR and Edith were when they desperately wanted love and marriage to survive the war against all odds. Out of those feelings is built the Doriath we have been shown in prose and poetry.

  • marionx

    Very nice site. 💙 I regret not to speak better English.

  • SikhHawk

    JRRT was young & just got the name wrong, it is clearly cow parsley but I much prefer to call it fairy lace. There is a place in the west midlands called blue bell wood near a road called wood end where during may & june this fairy lace cow parsley emits a fragrance beyond compare. to walk amongst it is to ascend the highest plane of aromatic bliss.

    • Michael Flowers

      He didn’t necessarily get the name wrong. Cow parsley is also known as Queen Anne’s lace. This just wouldn’t have been appropriate for his mythology. It would prompt the question who was Queen Anne? Also, Cow Parsley may have brought the wrong connotations of milk maids rather than Elven princesses. Hemlock, Cow parsley and the rest are members of the Umbellifer family. He could have called it by all sorts of names…
