'Rouletii' rose References
Book  (1991)  Page(s) 9.  
 
Pompon de Paris and Rouletii are so alike -- bright pink, hardy and easy to grow -- that they have frequently been confused with each other... The difference is that 'Pompon de Paris' tends to grow much leggier than 'Rouletii'...


Surely the truth was written by the man who eventually introduced it, Henri Correvan [sic. The name used by Monsieur Correvon was Henry Correvon]:
"My friend, Colonel Roulet, infomred me that he has a potted midget rose bush which grew on the window-ledge of a cottage at Mauborjet [Switzerland]. He told me that the rose bush had been grown in the pot for a century, that it bloomed from one end of the summer to the other, that it was absolutely dwarf and that it had belonged to the same family for the last 150 years. He offered to give me some branches for rooting." Correvan succeded in propagating it and goes on: "I realized this was an interesting variety. That was in 1917, and in 1920, we were in a position to deliver certain quantities." The little pink rose was soon the rage of the market place, and, in considertion of his friend's find, Correvan named it R. rouletii or, as the name should be, 'Rouletii'.

.

Jan de Vink crossed 'Rouletii' with the orange-scarlet Polyantha 'Gloria Mundi', a red hybrid Rugosa from 1918, 'F.J. Grootendorst', and a Hybrid Tea of unknown parentage... one of the roses that was produced was crimson with a white centre and named 'Peon'.

('Yu Ling Long'; 'Exquisite Jade') low and spreading … rosettes of 20 petals. .. Perhaps that is the nearest we shall now discover to the lost R. chinensis minima, ancestor of all true Miniatures… A few survived in Switzerland … [named for] their discoverer, Rouletii. All modern true miniatures come from them.

It was so named after Colonel Roulet, a medical officer in the Swiss Army; he obtained it in the Jura, from the village of Mauborget, where the villagers grew it in pots on their window ledges... In 1917 Colonel Roulet had given some stems to a friend of his in Geneva, a plantsman named Henri Correvon. Correvon was able to supply plants from 1920, and he named it 'Rouletii'. Fifteen years later, Ralph Moore first saw the wonderful little rose, and held his future reputation in his hands...

Rosa chinensis ‘Minima’ /Rosa chinensis var minima (Sims) Voss /Rosa indica pumila Thory/ Rosa lawranceana Sweet /Rosa indica minima Bean /Rosa indica humilis Ser./ Rosier bijou /Rosier du Bengale nain/ Rosier du Bengale pompon /Rosier de Miss Lawrance /Rosier pompon – en anglais Fairy Rose. 25 à 50cm de haut. Fleurs: 3cm de diamètre. Ce petit rosier frêle, aux tiges grêles, donnent de petites fleurs simples, légèrement doubles, selon le type, d’un rose pâle, de juin aux gelées. Ses origines sont confuses. Qu’il s’agisse d’un hybride entre un Rosa chinensis et Rosa gigantea, cela est très plausible. Qu’il soit né en Angleterre en 1805, cela l’est aussi… mais de graines venues d’où? Un des parents supposés, Rosa gigantea, est en effet arrivé en Europe en 1889 seulement. On dit aussi qu’il est venu de l’île Maurice (alors appelé Île de France), en 1810. Cela est plus probable car, depuis longtemps, cette île était visitée par les Chinois qui avaient très bien pu amener des rosiers de leur pays. Il n’est pas du tout impossible que le botaniste A.-P. de Candolle ait reçu Rosa chinensis ‘Minima’ de l’île Maurice, et qu’il l’ait cultivé et répandu dans le Jura suisse. Cent ans après, en 1917, le major Roulet trouve dans cette même région, un minuscule rosier, dans un pot, sur l’appui d’une fenêtre d’auberge, à Mauberget. Henri Correvon, qui habite tout près, est alerté… mais le village brûle! Heureusement, dans les environs, Henri Correvon trouve un rosier identique et en obtient des boutures. Il le diffusera, à partir de 1925, sous le nom de Rosa rouletii (voir p160). On a longtemps supposé que ‘Rouletii’ était une mutation directe de Rosa chinensis ‘Minima’; mais comme il a donné une fois, par réversion, Rosa chinensis ‘Pumila’, il y a tout lieu de penser qu’il procède de ce Rosa chinensis ‘Pumila’. Où et quand exactement s’était produite cette réversion? On le saura sans doute jamais.

'Rouletii'
Leaflets ¼ to ¾ in. long...Flowers very double, rosy pink, produced in erect clusters.
Nothing is known of the origin of 'Rouletii'. It is one of the pygmy forms of R. chinensis, and Boulenger suggested that it was the original 'Pumila'. Graham Stuart Thomas hs noted that in fact it reverts to 'Pumila', of which it must therefore be a mutation, rather than the original form.
'Rouletii' is the parent of a new race of miniature roses....

from "History and Nomenclature of the Fairy Roses" by Dr. G.H.M. Lawrence
[includes an good history of The Fairy Roses and explains the botanical nomenclature associated with the various cultivars]
The Fairy Roses include a wide range of variants, propagated commercially as named clones. They have been in cultivation since at least 1810 and probably a decade longer. Any discussion of the taxonomy of these named clones should take into consideration the fact that historically they belong to two more or less well defined periods. Those of the first period (ending about 1920) appear to represent selections of selfed seedlings or chance mutations of original stocks of what is now known as Rosa chinensis var. minima, or of intravarietal crosses between these stocks.

Those of the second period include also hybrids with other species, and their derivatives. The second period began with Correvon's introduction in 1922 of what he called Rosa Roulettii, a plant not distinguishable from the rose Pompon de Paris which is believed to be a derivative of R. chinensis var. minima. This derivative, and selfed seedlings of it, have been among the principal progenitors of the score or so of variants now in the trade. They differ from those of the first period in that a majority resulted from crosses between Pompon de Paris [i. e., " Roulettii"] stocks and dwarf floribundas and polyanthas. Horticulturally it is not always possible to differentiate clones of interspecific hybrid origin (most of those now cultivated) from the much earlier ones of infraspecific hybrid origin. For this reason it would seem expedient, if not biologically accurate, to group them as clones of a single taxon (i. e., R. chinensis var. minima).

BOTANICAL ORIGINS AND NAMES
There are many ideas and some uncertainty current among rosarians as to the correct botanical name for the miniature Fairy Rose. In the first place, one must decide if these plants are to be treated as a species distinct from other rose species, or if they represent a variant of an earlier named species. This decision is a matter of opinion, i. e., an opinion that can most reliably be reached after one has a knowledge of rose species as a whole and an understanding of the range of variation and of the genetic stability (or instability) of these species. This paper does not attempt to answer the question, but rather presents the views of some specialists and points out which name is to be used in either case.

CHINENSIS MINIMA VAR. ROULETTII is the smallest of all roses. Found by M: Correvon in Switzerland in 1829, it is a perfect miniature seldom exceeding three inches in height, when able to produce many flowers of rose-pink in quick succession. Correvon 1829. Deciduous. Short growth. Fragrant...June-October. Hardy.

R. Rouletti (Lawrenciana) Corr. ca. 1825; carmine-pink, fades to light pink, 2 cm., well double, flat, imbricated, fragrance 4/10, floriferous, continuous bloom, small dainty foliage, growth 3/10, bushy, 20. cm.

Dwarf form of R. semperflorens or bengalensis. = R. semperfl. minima Miss Larence. Colonel Roulet found her again in the Swiss Jura hills.

The much-discussed Rouletti rose, of which one can make lovely borders, is none other than R. semperflorens minima (R. Lawranceana)... one of the roses that did well on the Côte d'Azur and which the author believed would be suitable for California and Florida.
