Flashing flowers

by Fred Blick

Few readers will be aware of the ‘Elizabeth Linnaeus phenomenon’ today; yet over a span of almost two hundred years botanists, gardeners and scientists speculated about it. Elizabeth was the eldest daughter of the famous botanist, Carl Linné, known as Linnaeus.

Elizabeth Linneaus

One evening in the early 1760s, she was enjoying her father’s summer garden at Hammarby, near Uppsala, Sweden. She noticed how the “yellow … brilliant” flowers of the nasturtium appeared to gleam unexpectedly brightly in the half-light: so much so that they appeared to be emitting flashes or sparks.  So confident was she in her repeated observations that she shared them with her learned, botanist father and other philosophers and in particular with the celebrated electrical expert, Johan Wilcke. The latter concluded that the scintillations could be “related to ubiquitous Electric materials”. Although she was only nineteen, Elizabeth published her findings in an article entitled “Om Indianska Krassens Blickande” (“On the twinkling of Indian Cress”). This was recorded in the Acts of the Royal Swedish Academy of Sciences for 1762.

 

In 1783, a Natural History lecturer, Lars Haggren, conducted further experiments and confirmed the phenomenon of ‘flashing’ flowers. He found that the marigold of “orange or flame colour” flashed light on dry, dusky evenings, as well as the “yellow … brilliant” nasturtium which had been seen by Elizabeth.  He also confirmed that  “…it might be conjectured, there is something of electricity in this phaenomenon”.  British journals also published the discovery and Erasmus Darwin (grandfather of Charles) published his version of the findings in April 1789 in his The Botanic Garden. Many of these poems explore light, heat and electricity, their effects on plants and other living things:

On wings of flame, ETHEREAL VIRGINS! sweep
O’er Earth’s fair bosom, and complacent deep;
Where dwell my vegetative realms benumb’d,
In buds imprison’d, or in bulbs intomb’d,
Pervade, PELLUCID FORMS! their cold retreat,
Ray from bright urns your viewless floods of heat;
From earth’s deep wastes electric torrents pour,
Or shed from heaven the scintillating shower;
Pierce the dull root, relax its fibre-trains,
Thaw the thick blood, which lingers in its veins;
Melt with warm breath the fragrant gums, that bind
The expanding foliage in its scaly rind;
And as in air the laughing leaflets play,
And turn their shining bosoms to the ray,
NYMPHS! with sweet smile each opening flower invite,
And on its damask eyelids pour the light.

In the footnotes to this stanza, Darwin explains the scientific basis (as he saw it) of the influences of heat, “scintillating” light and electricity upon “vegetative realms”. This was directly influenced by Elizabeth Linnaeus and her ‘flashing flowers’.

 

In the autumn of 1793, Darwin’s poems and William Wordsworth’s newly published ‘An Evening Walk’ and ‘Descriptive Sketches’ were the subject of “a good deal of literary & critical conversation” between Samuel Taylor Coleridge, Wordsworth’s brother Christopher Wordsworth, and their university friends at Cambridge. It was thus by means of Darwin’s poems that Elizabeth Linnaeus’ observations reached the pioneers of English Romanticism. Botany and Natural History had both a scientific and homely appeal to Wordsworth and Coleridge, because they could be enjoyed by all – men, women and children alike. Yellow and gold flowers would never seem quite the same again, having acquired mysterious qualities of vitality, light and electricity. Likewise light was now associated with electricity and took on a special significance for them, sometimes symbolic of Love, as in Wordsworth’s ‘Among all lovely things my love had been’ (also called ‘The Glow-worm’) of 1802 and Coleridge’s ‘A Day Dream’, stanza 3, of the same year.

 

Only two years after leaving Cambridge, Coleridge wrote ‘Lines Written At Shurton Bars, Near Bridgewater, September, 1795, In Answer To A Letter From Bristol’. It was a love poem for his future wife, Sarah Fricker, and was published in 1796 in his Poems on Various Subjects. In it, Coleridge combined passionate, sexual love with the influences of both light and electricity:

‘Tis said, in Summer’s evening hour
Flashes the golden-colour’d flower
A fair electric flame:
And so shall flash my love-charged eye
When all the heart’s big ecstasy
Shoots rapid thro’ the frame!

Coleridge appended an end note to the poem which he reproduced substantially from Darwin’s Supplement to The Loves about the flashing flower. Clearly, Coleridge was drawing on the electric effect described in Elizabeth Linnaeus’ article of 1762.

Poems on various subjects

 

By the late 1790s, light, electricity and electro-chemical processes were popular topics, thanks in part to the experiments of Galvani, Volta, and Humphry Davy. In September 1801, when he was staying with Coleridge in Keswick, Robert Southey wrote:

I miss the sun in heaven, having been on a short allowance of sunbeams these last ten days; and if the nervous fluid be the galvanic fluid, and the galvanic fluid the electric fluid, and the electric fluid condensed light, zounds! What an effect must these vile, dark, rainy clouds have on a poor nervous fellow, whose brain has been in a state of high illumination for the last fifteen months!

 

Over many years Wordsworth composed poems about golden or yellow flowers. One example which most readers will recall is the daffodils of ‘I wandered lonely as a cloud’ of 1804, which was inspired by Dorothy Wordsworth’s journal record of daffodils at Ullswater on 15 April 1802. Though he described the daffodils twice as “dancing” in the printing of 1807, he changed the first “dancing” to “golden” in the 1815 version. Further, and crucially in this context, he accepted, his wife Mary’s suggestion of the lines,

They flash upon that inward eye
Which is the bliss of solitude.

Not only did the flowers “flash” but “Out-did the sparkling waves in glee”. These golden, flashing and dancing flowers, recorded also as “ever glancing” in Dorothy’s journal entry, appear to have been derived directly from Elizabeth Linnaeus’s description of her “yellow … brilliant” nasturtiums as “blickande” (glancing or twinkling) and possibly affected by electricity.

Flashing flowers

 

Elizabeth Linnaeus also “consider[ed] for a while that this [flash] might derive from a positioning of the eyes” rather than from electricity within the plant. Both Wordsworth and Coleridge came to the conclusion that the flashing effect was indeed in the eye, and not the flower. They became persuaded that the phenomenon was in the nature of an “Ocular Spectrum” or “After Image”. In 1810, the poet and scientist J.W. von Goethe had also questioned whether the flashing seen in flowers was actually in the flower or in the eye.

 

Wordsworth later added a note of explanation about the “flash” to his ‘Daffodils’ poem in the 1815 printing: “The subject of these Stanzas is rather an elementary feeling and simple expression (approaching to the nature of an ocular spectrum) upon the imaginative faculty, rather than an exertion of it.” Coleridge later acknowledged grudgingly in his Literaria Biographia of 1817 that the concept of “visual spectrum” was indeed “a well known fact”, but at the same time he criticised Wordsworth’s lines about the “flash” as being “mental bombast”, inappropriate for describing the “joy of retrospection”.

 

So what does modern science make of the phenomenon? In 1914, Professor F.A.W. Thomas wrote in the scientific journal, Nature, as that the “Flashing Flowers” (or “Elizabeth Linnaeus phenomenon”) really did exist, and that it was caused by an image of red light moving across the retina of the eye. In 1937, Professor M. Minnaert classified the same phenomenon as an “After Image”. In other words, it has been established that Elizabeth’s “flashing” was an effect within the eye, exactly as Wordsworth and Coleridge eventually came to believe.

 

Fred Blick is an independent scholar from a multi-disciplinary background. He has published a number of essays over the past twenty years; not only “Wordsworth’s Dark Joke in ‘The Barberry-Tree’” in Romanticism journal in October 2014, but also innovative essays in peer-reviewed academic journals worldwide on the subjects of the Sonnets of William Shakespeare and of Edmund Spenser.

  1. I found this a very interesting article, especially as I had been reading a discussion of Elizabeth Cristina’s observations in Pulteney’s ‘Historical and biographical sketches of the progress of botany’ vol 1 (p 345-6) 1790 (accessible on Google Books). This book and Pulteney’s ‘A general view of the writings of Linneaus’ 1781 are perhaps the main conduits of Linneaus’ non-systematic ideas in to Britain.

    1. Thank you Gareth Evans for your interest and for the book references.
      You are probably aware that at p.137 of The Botanic Garden Part II The Loves…, 1789 Erasmus Darwin cited “Pulteney’s view of Linnaeus, p. 220” when he first referred to Elizabeth’s discovery of flashing flowers. The general interest aroused by Pulteney’s work on Linnaeus led eventually to Wordsworth and Coleridge satisfying the longing of Dorothy for “a book of botany” (Journal 16 May 1800). They acquired in March 1801 two copies of the third edition of William Withering’s An Arrangement of British Plants … (1796). The influence that botanical books had on Wordsworth’s various poems about flowers and plants seems yet to be fully researched.
