'Slater's Crimson China' [was] lost for years, than found again in 1956, naturalized in Bermuda! To this, or something similar, we owe the origin of the first east-west hybrid … the 'Duchess of Portland' … the other parent was maybe a Gallica or Damask… it came to England around 1800 … it was the first hybrid to combine the eastern genes for extended flowering with the western ones for hardiness and vigour, and it was the bringer of red into our garden roses.

p9 One of the most exciting events in the early days of the Society was the positive identification in 1956 by Mr. Richard Thomson of R. chinensis semperflorens or 'Slater's Crimson China', better known to Bermudians as the "Belfield" rose. Mr. Thomson, Chairman of the Old Rose Committee of the American Rose Society at that time, found the rose growing at Belfield in Somerset in 1953 and was quoted as having said that at first he could not believe his eyes. He felt like an art collector who had "just unearthed a long-missing Rembrandt". After three years of intensive research, he finally confirmed his original opinion. Much was written about his discovery in English, American and Canadian papers and rose publications at that time as this rose was thought to have been lost to cultivation and its rediscovery was a cause for great excitement. There then followed an epic journey when Mrs. Harry Richardson and her husband sailed to Englandand accompanied by five little plants and the famous rose was re-introduced into England to the delight of everyone and was shown at the Chelsea Flower Show the following year.

p18. Plate 10. R. chinensis semperflorens or 'Slater's Crimson China' (1792). The story of how this rose was found to be growing in Bermuda under the name of "Belfield" has already been told on p9. Since then the Rose Society has propagated it intensively and most members now have a bush. It is a very slow growing small bush, reaching a height of up to 3 ft. It has dark green foliage, rather spindly, with small red single flowers, 2" across.

Since my short note on this rose in last year's Rose Annual, Mr. Graham Thomas has queried my equating it with 'Slater's Crimson China' because the taller form, found in Bermuda, perhaps better matches the original description. However, Rowley has described this Bermuda form as having scarlet petals and sepals glandular; by contrast Miss Willmott's form and 'Cramoisi Superieur' both have crimson petals and sepals eglandular. In other words I maintain that Miss Willmott's form was the Stud China from which 'Cramoisi Superieur' and other related roses were bred. This also appears to have been Hurst's view.

p183. E. F. Allen. Reviewing The History of the Rose
Chapter 7 provides a good summary of rose breeding and development in the 19th century. However, 'Slater's Crimson China' is not a triploid; this claim originates from one of Hurst's rare errors and was corrected in Rowley's important paper on Ancentral China Roses (Journ RHS 1959, Vol 84, page 270).

Note for the 1978 Edition
Rosa Chinensis is not in cultivation. The species is a native of central China and is a tall climbing rose, leaves with 3-5 leaflets, flowers single, usually crimson, sometimes pink, produced in summer only. In this book - and many others - the R. chinensis usually quoted is one of four hybrids that were introduced to Europe around 1800, particularly 'Parson's Pink' which is now called 'Old Blush'.

R. chinensis 
The China Rose. This is perhaps the most moving story of past achievements we expect to record in these pages. The China Rose more than any other is responsible for nearly all the popular roses of the present time. It is at once the rose world’s greatest blessing and mystery.

The mystery comes of our being unable to identify any original species as the China Rose. R. chinensis itself is not a living entity, but a dried specimen in a herbarium collection of the Dutch botanist Gronovius. He labelled it. “Chineesche Eglantier Rosen’ in 1733, and now it rests in the British museum. It is most probably the same as a red China rose brought to Europe later in the 18th century; but nobody is really sure what it is. The true, natural species is supposed to be R. chinensis spontanea, but my remarks upon that rose will show that it is even more elusive; there is not even so much as a dried specimen of that one.
The truth appears to be that the China Rose was developed many years ago in that country of ingenious and long-civilised people, and we simply have no evidence how they did it. In the 18th century, Europeans saw China Roses on sale, the Fa Tee Nurseries in Canton being a celebrated source; and they bought them, and sent them home. It is a pity they did not pump the proprietors dry of all the knowledge they had. In due time, China Roses mated with Western roses, the Flower of East, and West meeting one might say, despite Rudyard Kipling, and the rose was magnified far beyond what had been seen hitherto. This example of human cooperation comes along free of charge with the beauty of modern roses. In a flower of ‘Peace’ there is not only the work of the Frenchman who raised it, but the hands of men who prepared the way to it, old hands, gnarled and buried a long time, Chinese, Persian, Chaldean, Mycenaean, Greek, Roman and who knows what else, up to the new hands, Irish, English, American and French. All subscribed to the making of ‘Peace‘; and were we to take the generality of roses instead of that one variety, we should embrace, nearly the whole of the nations in this peaceful and purely beneficial pursuit. ‘Peace has her victories, no less renowned than War.‘
I do not believe that we have, amongst the China Roses that came to the West, any true species, nor any botanic varieties. In my opinion, they are all Chinese cultivated varieties, and the source material is unknown to us. I suppose the original was a hybrid of the second or a subsequent generation, and the nearest parallel to such an occurrence in modern experience is R. kordesii. I fear this theory may bring the Hornets around my head, but it seems to fit the facts better than the accounts of R. chinensis written in the rose books.
Other names for the species have included R. sinica and R. indica, and on the latter hangs the explanation of the section name, Indicae: the Calcutta Botanic Garden was fairly active in collecting Oriental roses, and it was also cooperative in accepting shipments of plants from Chinese ports, and holding them (or perhaps reviving them) until a ship sailed for Europe. For this reason, the French in particular assumed that the plants came from Calcutta, and they called them ‘Bengal Roses’, which is still the common name in France and Germany; the specific name in Latin for Indian roses (R. indica) was therefore acceptable. I have often thought that botanists going to Calcutta in those days could hardly have believed their botanic fortune when they saw the plants of the Orient for the first time.
The chief blessing brought by China Roses was an extension of the flowering period from summer, even up to the gates of winter. It is easy to let that statement pass, but to arrest it, and emphasise its importance, let us repeat it in another way: until the China Rose came, nearly all European roses flowered for a few weeks, like the Cherry, the lilac, the Hawthorne, the Apple and the broom. The miracle of flowering again and again made the rose a very special plant.
 The shape of flower, which we take to be the traditional Rose, is no more traditional than appearing about the middle of the 19th century; and it comes, so far as we can judge, from the stock in trade of the Fa Tee Nurseries. The types of leaves, stems and bushes crowded into millions of rose beds about the world have the family stamp of the China Roses upon them. We know much of modern rose breeders, among whom are good and great men, but the greatest of all may be from long ago and quite unknown; and may their bones rest with our blessing in the soil of Mother China.
