Blue Edged Sweet Pea

'Cherub™ Northern Lights' is a modern approximation of 'Captain Clarke's Blue-edged'

My first encounter with this variety, and the idea that it resulted from a cross between a white sweet pea and Lord Anson's pea, led me to think that it might be a partial hybrid. When I learned that it actually originated from a cross between the Purple and the Painted Lady, I was still intrigued that such a cross could yield a blue and white picotee. Again, I was mislead.

Comparing descriptions, rather than trusting to names, I found that 'Captain Clarke's Blue-edged' eventually came to be known simply as 'Captain Clarke'.

'Butterfly' was sometimes sold as 'Blue Edged', confusing it with Trevor-Clarke's "hybrid".

Both of these varieties picked up another name or three as the strains were reselected and improved. 'Lottie Eckford', as it was originally, was little different from 'Blue Edge/Capt. Clarke', which is one of the strains Eckford used in breeding. However, the 'New Lottie Eckford', which eventually became the only 'Lottie Eckford', was a somewhat improved 'Butterfly'.

I don't know for sure where "Seedsman" (1897) got the idea that Lord Anson's pea was an ancestor of 'Blue Edge'. I do note that Trevor-Clarke also raised a Blue Primrose.

Gardeners' Chronicle p. 791 (June 19, 1875)
I fear I cannot give your correspondent a clean pedigree for my blue Primrose. Some years ago I crossed a white-stalked Primrose, using the pollen of the old blue, which, though itself sterile, bears fertile pollen. The seedlings were violet, with a decided tinge of the blue, and preserving other resemblances to the pollen-parent. They were fertile, and produced many seedlings much like themselves; finally, they were mixed up with my general stock. Last year I sowed seed from the best of my lot, and the plant in question came up amongst them. It is just a case of old blood coming out after many generations, hardly to be called atavism, which is applied to another and distinct phenomenon in the animal kingdom. The plant is bearing seed. My new double is just the old double lilac on stilts, but with a larger and somewhat handsomer flower. I shall feel happy in corresponding with "J. M.," or in any way assisting him in such matters.—R. Trevor Clarke, Welton Place, near Daventry.

Perhaps "Seedsman", or a friend, mis-remembered this note, and unconsciously replaced "white-stalked" with "white", and "old blue" with "Lord Anson's Blue". These scant details were then superimposed on the 'Captain Clarke's Blue Edged' sweet pea.

Major Clarke, on again proceeding, referred to the white Lily from Mr. G. F.

Sweet Peas.
At a recent meeting of the Royal Horticultural Society (on at which there was a fine horticultural display, but few, to witness it), bunches of flowers of all the cultivated Sweet Peas were exhibited by Messrs. Carter & Co. The group was one of peculiar interest, because Sweet Peas are so seldom shown. The brightest of all in colour was the Scarlet Invincible, a truly beautiful Sweet Pea, with its purple crest and clear bright scarlet wings. Purple Invincible is also a fine selection, the crest being maroon and the wings rich purple, while the flowers are large and bold. The Scarlet Sweet Pea has a purple crest and bright rose-coloured wings, and is very pretty, but lacks the size and brilliancy of Scarlet Invincible. Painted Lady is a pretty variety, the crest of which is pale purple, and the wings pink and white. The Invincible Striped gives us the Scarlet Invincible, with the wings flaked with white, on a scarlet ground. The blue-edged Painted Lady is a novel and charming variety, in which the pink and white wings become suffused with blue as the flowers age, imparting to it a very distinct appearance. The Scarlet-striped is simply the Scarlet Sweet Pea with the wings flaked with white, but is quite distinct as a variety. The Purple Sweet Pea is a pleasing, brightly-coloured variety, the crest of which is maroon and the wings bright purple. The Purple-striped has bright purple wings flaked and pencilled with white. Crown Princess of Prussia has a pale salmon-pink crest with dashes of rosy-purple, the wings being pale pink. A new variety named heterosperma is very pretty and distinct; it is a selection from the Invincible Scarlet: it has a delicate rose crest flushed with scarlet, and purple and white wings. Lastly comes an attractive new variety named Violet Queen; it was not exhibited with the foregoing, but I have since seen it growing at St. Osyth. It has a bright lilac crest and blue-violet wings, and can scarcely fail to be a favourite. There yet remains the white, with its small white flowers, very good as a variety and as affording a contrast to the dark-coloured varieties. It will thus be seen that there is quite a wealth of Sweet Peas, and, whether grown in patches of separate varieties or mixed together, they make charming garden plants both for decorative purposes and for affording cut flowers.—D.

PLATE CX. NEW SWEET PEA—BUTTERFLY.
Drawn by H. NOEL HUMPHREYS.
The Garden, 13 (1878), p. 44.
Butterfly—This beautiful variety was raised in Messrs. Sutton & Son's seed grounds at Reading. Its flowers, as will be seen, have a pure white ground, delicately laced with lavender-blue, tints which contrast admirably with the scarlet, black, rose, white, and other colours to be found in Sweet Peas already in cultivation. It therefore supplies a want hitherto existing in this favourite class of hardy, sweet-scented, climbing annuals. It possesses the same robust habit as the older varieties, and has proved itself to be perfectly true to colour and character. The annexed plate scarcely does justice to this Pea, owing to the difficulty experienced in giving to the flowers that softness and delicacy which they naturally possess. Vigorous plants of it sent us by Messrs. Sutton were covered with flowers, of which the plate gives only a faint idea, the flower being one consisting of neutral tints very difficult to render in colour printing. From having seen the plant, however, on several occasions, we may say that it is an annual of exceptional merit, and worthy of a place in every garden. It would deserve also what Sweet Peas so often do not get — good culture and a good position.

Live Stock Journal Almanack, p. 136 (1878)
In addition to the above, we would also call attention to the New Sweet Pea, known as “Butterfly,” which has been grown by Messrs. Sutton at Reading. The flowers have a pure white ground, and are delicately tinged with lavender blue. With the scarlet, black, rose, and other colours in cultivation it contrasts admirably. The spikes of bloom when cut retain their fragrance for a long time in water, which renders it a favourite specimen for the bouquet.

Crossing Sweet Peas
H. Eckford
I commenced my operations on the Sweet Pea four or five years ago, with the following kinds: Invincible, the Queen, Violet Queen, Captain Clark, Princess of Prussia, Butterfly, and what is generally known as the Black Sweet Pea. These, as in the case of the culinary Pea, were carefully prepared and crossed. The seeds produced from these crosses were sown singly in thumb-pots about the middle of January the following year, and kept in a cold frame till the plants were strong enough to turn out, which was about the end of March. They were planted three feet apart, about one hundred in number. Whether the vigour of the plants was stimulated by the crossing, or the thin planting, or by both, I do not now stop to determine, but the growth and display of bloom was truly unique. They made a row so dense that in some cases where a variety was considered to possess some merit worth perpetuating, it was found difficult to separate them without actually pulling them to pieces.

The Garden 33: 483 (May 26, 1888)
Out of thirty-one named varieties of Sweet Peas planted for trial last year, I found but nineteen really distinct kinds. Cardinal was practically identical with Invincible Scarlet; so was Princess Louise, with The Queen; Queen of the Isles, with Invincible Red Striped; Violet Queen and Grand Blue, with Light Blue and Purple; Purple Striped, with Black and White; Captain Clark and Lotty Eckford, with Blue Edged.
    No pink and white variety is as good as Painted Lady, though Crown Princess of Prussia is beautiful, but of lighter colour. Captain Clark has a white standard shaded with rose and veined with dark lines, and white wings tinged with rose and edged with purple. Fairy Queen is nearly pure white, with a few delicate crimson veins in the centre of the standard. Butterfly is white, faintly edged and shaded with blue.—A. H. Fewkes, in Garden and Forest.

You may buy the Lottie Eckford, but you will not get it of any house in this country this year. Every seedsman thinks he has it, but he has not. Mr. Eckford, himself, has lost the original Lottie Eckford, and this year begins over again with a new description.

[It appears that the original 'Lottie Eckford' resembled 'Blue Edged/Capt. Clarke', whereas the 'New Lottie Eckford' was more like 'Butterfly/Maid of Honor'.]

The New Lottie Eckford sweet-pea suggests the Butterfly in its form and color. When well grown, the blossom is of large size, the standard of one I have in hand measuring one and one half inches across the middle. The standard is considerably hooded. The wings are wide and quite horizontal with their front ends curving downward. Frequently the standard is double. In color, this Lottie Eckford is white at the bases of the petals, gradually assuming an increasingly deeper lavender hue toward the outer edge, and the edges are fringed with a distinct line of lavender. This is a very charming variety, which one would be loath to omit from even a small collection.

The Butterfly sweet-pea is a charming variety on account of the delicacy of its colors and the airy grace of its form. In both respects it resembles the New Lottie Eckford, which, however, is a considerably larger blossom. A mass of the Butterflies is quite unique in its fluffy effect.

The Captain Clarke is a tri-colored sweet-pea, but it is not very pleasing in its color effect. The standard is tinged with a light tint of violet red, especially on the front surface, while the wings are white, edged with a tint of blue violet. The flowers are rather small, with flat standards, but the plant blooms profusely.

Sweet Peas
"Seedsman"
In 1837 I notice Mr. Carter offers a similar list, with a striped form added; whilst in 1850 he includes "new large-flowered." In 1860 he gives nine varieties and a yellow-flowered one, and also blue-edged, to which the Royal Horticultural Society gave a First-class Certificate many years later. On August 22, 1883, this novelty was first named Blue Hybrid, and it was understood to have been a true hybrid between the annual white Sweet Pea and the perennial Lord Anson's Blue, now almost lost to cultivation. It was the outcome of a series of experiments made with the object of raising a real blue flowered variety by Col. Trevor Clarke of Daventry.

    [This is the earliest mention that I've found of the fabled connection with Lord Anson's Blue Pea. I cannot verify the name 'Blue Hybrid'. The earliest names were 'Captain Clarke's Blue Edged' and 'Captain Clarke's Hybrid'. 
    Perhaps there was a typesetting problem in this note. As printed, it suggests that the variety was first named 'Blue Hybrid' on August 22, 1883, which seems odd as well as inaccurate. The alternative: "... and also blue-edged, to which the Royal Horticultural Society gave a First-class Certificate many years later, on August 22, 1883. This novelty was first named Blue Hybrid ..." 
    The variety was actually called 'Blue Edged' in 1859, and 'Blue Edge' when it received its certificate in 1883.]

Rhode Island Bd. of Agric. (1897)
In 1837 James Carter, Holborn, London, quoted in his catalogue, black, painted lady, purple, scarlet, white, striped and yellow. This brings us to the renaissance of the sweet pea. Although in my visit to England in 1895 I endeavored to get from the older seed houses the dates of the introduction of the first improved sorts, and such new colors as had begun to appear, I am very willing to trust Mr. Dicks' data, for his opportunity to make a thorough search is unequalled. He says the blue edged variety was offered by James Carter in 1860, although in 1883 this variety was named blue hybrid, and was thought to be a true cross between the white sweet pea and Lord Anson's blue, and was the outcome of a series of experiments made by Colonel Trevor Clarke, of Daventry. Butterfly, as offered by Sutton in 1880, was practically identical with this.
    Mr. Dicks and I agree on the introduction of invincible scarlet in 1865, a first-class certificate being awarded to Stephen Brown, of Sudbury. Carter put it out. In 1867 an improved purple called Imperial Purple was offered. Mr. Dicks traced the introduction of Crown Princess of Prussia to Haage & Schmidt, 1868-1869. This was the beginning of the soft pink varieties. The Carters told me they put out Violet Queen in 1877. Haage & Schmidt offered Fairy Queen in 1873-74 (as per Mr. Dicks) and also Lilacine Splendens, which they claimed to be superior to Capt. Clarke, but the latter has held the field.

The Sweet Pea: The Flower for Everybody
Rev. W. T. Hutchins
Carter put out the names Invincible Black and Invincible Scarlet Striped about 1880. Soon followed Lilacina Splendens, now a doubtful variety, although we still have the name Splendid Lilac. I suspect this latter is what more commonly became the Captain Clarke.

[I think it far more likely that 'Captain Clarke's Blue Edged Hybrid' was the one that came to be known as 'Captain Clarke'. If 'Butterfly' had never been renamed 'Blue Edged', not even Hutchins could have confused it with Clarke's strain.]

American Florist (Feb. 12, 1898)
Sweet Peas Still in the Ascendant.
W. T. Hutchins
But there is another side to this matter. The ruinous under cut in contract prices has forced our best growers to some kind of protection. They have found a little relief in novelty stock. In all fairness they are entitled to it. If I know that a certain grower will take special pains with an improved strain of some old popular sort, and that he will father that improved strain, and feel a special obligation to hold it up in quality, I am willing he should rename it, and get some just compensation for his work on it. He could get nothing for growing the old deteriorated stock. Butterfly was Butterfly till it run out. Now it is better than ever as Maid of Honor, and when that deteriorates they can call it Maid of Orleans if they want to, just so they give us back good stock of that dear old blue edged sweet pea. There never was any sense in calling it Butterfly, anyhow.

Gardeners' Chronicle, 28(708): 50 (July 21, 1900)
From that time till 1860 little seems to have been done till the last-named year, when a blue-edged variety was brought out, and said to have been a true cross between the annual white Sweet Pea and the perennial Lord Anson's blue. Were it not that the name of Col. Trevor Clarke is mentioned as the raiser, we should not have attached much importance to the statement. It is not mentioned in Dr. Focke's standard book on Hybridisation. [CybeRose note: Focke did discuss Darwin's cross, detailed below.]

American Gardening 21(292): 501 (July 28, 1900)
Chronological Contributions to the History of the Sweet Pea
By a member of the staff of Messrs. Carter's, London, Eng.
I have traced through several seed catalogues and cannot find any other additions to the list until we come to the Blue Edged as brought out by us in 1860. Sweet Peas were only in their infancy in popular favor in these days, and we did not submit this variety to the Royal Horticultural Society until August 22, 1883, when it was given their first-class certificate. It was understood to have been a true cross between the annual white Sweet Pea and the Perennial Lord Anson's blue. It was the outcome of a scries of experiments made with the object of raising a real blue flowered variety by Major Trevor Clarke of Daventry.

[The Carter's ad from 1859 (above) clearly states that 'Capt. Clarke's New Hybrid Sweet Pea' was derived from Painted Lady and the Purple; and the description in 1883 agrees with that of 1859 about the light rose standard.]

D B Crane, The Book of the Sweet Pea (1910)
Reverting to 1860 we find a blue-edged variety was offered by Mr James Carter to which the Royal Horticultural Society gave a First Class Certificate at a later date. Twenty-three years later (1883) this same variety was first named Blue Hybrid. It was understood to be a true hybrid between the perennial Lord Anson's Blue and the annual white Sweet Pea. It was one of a series of experiments that were made, with the definite object of procuring a real blue-flowered kind, by Colonel Trevor Clarke of Daventry. Not the least interesting fact in this connection is that Butterfly, offered by Messrs Sutton & Sons, in 1880, is practically identical with this variety. 

Beal: Sweet Pea Studies (1912)
The variety Blue Edged, the probable forerunner of the picotee forms, appeared in 1860. This was a white variety with a well-defined blue edge, a possible hybrid between L. Magellanicus and a white variety of L. odoratus. The variety, at all events, was the first to exhibit a distinct blue color among sweet peas. Later it was known as Blue Hybrid, under which name it won an award from the Royal Horticultural Society. Sutton & Son sent out Butterfly* in 1878, which somewhat resembled Blue Edged. The so-called "blues" that followed were Invincible Blue, Madame Carnot or Imperial Blue, and Captain of the Blues, all of which had considerable red in the standard. It was not until 1899 that a good blue appeared, in Navy Blue (Lord Nelson).
*See color plate in The Garden, 13 (1878), p. 44. (above)

[Beal should have checked his facts rather than relying on other writers. In fact, the 1883 Certificate was awarded to 'Blue Edge'.]

Annual Report, New York (State) Dept. of Agriculture 2(1): 687 (1912)
In 1860 Mr. Carter offered nine varieties, besides a yellow-flowered variety and the variety Blue Edged. The last-named variety was white, with a well-marked blue edge, and it was stated that it was the result of many experiments made by Major Trevor Clarke, of Daventry, in crossing a pure white sweet pea with the perennial bright-blue-flowered Lord Anson's pea, L. Magellanicus. Later, in 1883, under the name "Blue Hybrid," this variety received the First Class Certificate of the Royal Horticultural Society.

Gardeners' Chronicle of America 16(9): 570 (July, 1913)
The lesson is that if the grower does not intend to comply with the requirements of the improved types, it is better to grow Butterfly, Captain Clarke, Peach Blossom, and other small-flowered, precocious varieties.

There is more than a little confusion as to the identity and proper name of Lord Anson's Blue Pea.. Here are three possibilities that have been mentioned.

Gardening Illustrated 21-372 (Sept. 16, 1899)
L. Magellanicus,
from the Straits of Magellan, is known by the name of Lord Anson's Blue Pea. The species is said to have been originally introduced by the cook of H.M.S. Centurion, of which ship Lord Anson was captain, in 1744, and bears flowers of a beautiful blue tint. It is a perennial species, but at the present date is apparently lost to cultivation. L. Armitageanus is sometimes sold for it, but more often would-be purchasers are put off with a blue variety of L. sativus.

Mrs. Loudon (1843) lists L. Armitageanus as a synonym for L. magellanicus, whereas Cree (1829) identifies L. sativa as Lord Anson's Pea.

2. L. Magellanicus—Lord Anson's Pea.—Between this and a common weed in Bengal, which bears small bright blue flowers, there seems to be scarcely a perceptible difference.


It is interesting to note that in the 1860s, the "hybrid" was reported to have been between Painted Lady and the Purple (now called Cupani). Brent and Darwin also crossed the two varieties, and the results are not too dissimilar from early descriptions of Clarke's variety. In addition, there were even earlier reports of "Painted Ladies" combining white, pink and blue.

Martyn's edition of Miller's Gardeners' Dictionary 1807:
"In the common sort the corolla has dark purple standards, with the keel and wings of a light blue. Other varieties are the white; the pink with a white keel and wings pale blush color; the rose-coloured standard with keel and wings pale blue; these that have a mixture of red with white or a pale blue are called Painted Lady dies. There is also a variety of the common dark sort with the keel pale violet and the wings dark violet, etc."

Cross Breeding Sweet Peas.—I perceive Mr. Beaton, in The Journal Of Horticulture, May 14, says he does not know of any one who has obtained a true cross in any of the Pea-flowering plants. I do not know if the following will interest him. About the year 1836 I crossed the Painted Lady and Purple or Puce Sweet Peas. I obtained very few seeds, and these the next season produced grizzled and striped blooms, being a mixture of the two colours. I do not know if Mr. Beaton will consider this a true cross.—B. P. Brent.

Darwin: Variation of Animals and Plants 1: 507
It may be worth mentioning that I fertilized the Purple Sweet-pea (Lathyrus odoratus) with pollen from the light-coloured Painted Lady: seedlings raised from the same pod were not intermediate in character, but perfectly resembled either parent. Later in the summer, the plants which had at first borne flowers identical with those of the Painted Lady, produced flowers streaked and blotched with purple; showing in these darker marks a tendency to reversion to the mother-variety.

Darwin: Variation of Animals and Plants 2: 93 (1868)
I fertilised the purple sweet-pea (Lathyrus odoratus), which has a dark reddish-purple standard-petal and violet-coloured wings and keel, with pollen of the painted-lady sweet-pea, which has a pale cherry-coloured standard, and almost white wings and keel; and from the same pod I twice raised plants perfectly resembling both sorts; the greater number resembling the father. So perfect was the resemblance, that I should have thought there had been some mistake, if the plants which were at first identical with the paternal variety, namely, the painted-lady, had not later in the season produced, as mentioned in a former chapter, flowers blotched and streaked with dark purple. I raised grandchildren and great-grandchildren from these crossed plants, and they continued to resemble the painted-lady, but during the later generations became rather more blotched with purple, yet none reverted completely to the original mother-plant, the purple sweet-pea.

Darwin: Effects of Cross and Self Fertilisation (1877)
In order to ascertain what would be the effect of crossing two varieties, some flowers on the Purple sweet-pea, which has a dark reddish-purple standard-petal with violet-coloured wing-petals and keel, were castrated whilst very young, and were fertilised with pollen of the Painted Lady. This latter variety has a pale cherry-coloured standard, with almost white wings and keel. On two occasions I raised from a flower thus crossed plants perfectly resembling both parent-forms; but the greater number resembled the paternal variety. So perfect was tho resemblance, that I should have suspected some mistake in the label, had not the plants, which were at first identical in appearance with the father or Painted Lady, later in the season produced flowers blotched and streaked with dark purple. This is an interesting example of partial reversion in the same individual plant as it grows older. The purple-flowered plants were thrown away, as they might possibly have been the product of the accidental self-fertilisation of the mother-plant, owing to the castration not having been effectual. But the plants which resembled in the colour of their flowers the paternal variety or Painted Lady were preserved, and their seeds saved. Next summer many plants were raised from these seeds, and they generally resembled their grandfather the Painted Lady, but most of them had their wing-petals streaked and stained with dark pink; and a few had pale purple wings with the standard of a darker crimson than is natural to the Painted Lady, so that they formed a new sub-variety. Amongst these plants a single one appeared having purple flowers like those of the grandmother, but with the petals slightly streaked with a paler tint: this was thrown away. Seeds were again saved from the foregoing plants, and the seedlings thus raised still resembled the Painted Lady, or great-grandfather; but they now varied much, the standard petal varying from pale to dark red, in a few instances with blotches of white; and the wing-petals varied from nearly white to purple, the keel being in all nearly white.
     ....Another variety, however, is often sold, which is striped and blotched with dark purple; and this is probably of crossed origin, for I found, as well as Mr. Masters, that it did not transmit its characters at all truly.

Darwin: Effects of Cross and Self-Fertilisation
But some flowers of the Painted Lady, castrated at an early age, were fertilised with pollen from the Purple sweet-pea; and it should be remembered that these varieties differ in nothing except in the colour of their flowers. The cross was manifestly effectual (though only two seeds were obtained), as was shown by the two seedlings, when they flowered, closely resembling their father, the Purple pea, excepting that they were a little lighter coloured, with their keels slightly streaked with pale purple.

According to Henry Phillips (1824), "Linnaeus tells us that the common dark variety is a native of Sicily, and that the more delicate-coloured kind, which is distinguished by the name of the Painted Lady, is an indigenous plant of Ceylon. These two kinds have lately been blended by the art of the florist, or by accidental impregnation, and have produced a variety with striped petals."

21 Verlot, 'Des Variétés,' 1865, p. 63. The discussion of striped flowers begins on the page numbered 156 in the PDF.
Also, Verlot, 1864 pt. 5
This seems to confirm what Darwin (Variations) wrote: "Vilmorin21 has also recorded several cases with plants derived from seed, of flowers reverting by stripes or blotches to their primitive colours: he states that in all such cases a white or pale-coloured variety must first be formed, and, when this is propagated for a length of time by seed, striped seedlings occasionally make their appearance; and these can afterwards by care be multiplied by seed."

I have learned that the standard or banner of the Purple has about 4 times as much pigment as the wings; but the wings have about 6 times the co-pigment. This explains why the Purple is two-colored rather than merely two-toned. The Scarlet appears to differ from the Purple by the loss of co-pigment. Thus, the difference in pigment density is clearly shown. The Painted Lady differs from the Scarlet by a general reduction in pigment, leaving the banner pink, and the wings white and faint pink.

Development of Anthocyanin Pigmentation in Flowers of Lathyrus odoratus
R. C. PECKET

A quantitative study has been made of developmental changes in the anthocyanins and a flavonol glycoside in the red/blue bicoloured flowers of Lathyrus odoratus L. Anthocyanin formation occurs during the period of most rapid growth of the petals. At maturity about four times as much anthocyanin is present in the standard petal as in the pair of wing petals, which are together comparable in fresh weight to the standard. The pattern of development of flavonol glycoside is quite different; some are formed well before anthocyanin formation occurs and at maturity about six times as much flavonol glycoside is present in the wings as in the standard per unit amount of anthocyanin. Some further evidence is thus provide that the flavonol glycoside may be acting as a co-pigment which modifies the wing petal colour to blue.

When the Painted Lady is back-crossed to the ancestral Purple, the addition of co-pigment to the Painted Lady pigmentation gives a darker rose colored standard, with "blue" tinged wings. However, the reduced pigmentation of the "Painted Lady trait" appears to be variable, some strains lighter, others darker. This also affects the 'Blue Edge' strains, sometimes giving such a faint color in the Standard that the flowers almost resemble 'Butterfly' in color, though not in form.

Lord Anson's Pea, from Mrs Loudon (1843) In the colored plate the center flower is known as Scarlet. In this it may be noticed that the petals forming the keel are white, the wings rose-colored, and the banner scarlet. At the right of this center flower is one with white keel and very dark crimson wings and banner, this variety in the trade is called Black. Directly underneath the last mentioned one is what is known as Blue Edged. Above the center flower, Scarlet, is one with white keel and white wings and a rose-colored banner; this is Painted Lady. At the upper left-hand corner of the group is Scarlet Invincible, having a white keel and scarlet wings and banner.

Flora domestica: or, The portable flower-garden (1823)
Elizabeth Kent, Leigh Hunt

The Sweet-pea has several varieties, greatly differing in colour: the common sort, which is blue and dark-purple, sometimes with a tinge of red, is a native of Sicily. The more delicate kind, white and blush, or white and deep rose-colour, sometimes with a mixture of pale blue, is a native of the Island of Ceylon, and is called the Painted-lady.
