[From "The finding of Rosa rouletii" by Marlise Fertig]
.....the following account by H. Correvon taken from his work Floraire, is probably the most authentic account with the possible exception of the reported age of the plant. It states as follows:
My friend, Roulet, informed me one day that he had a potted midget rosebush which grew on a window ledge of a cottage at Mauborget (at 1176 meters above sea level); he told me that this rosebush had been grown in this pot for a century, that it bloomed from one end of the summer to the other, that it was absolutely dwarf and belonged to this family for the last 150 years. He offered to give me some branches of it for rooting. We succeeded in propagating it, and from the beginning, I realized that this was an interesting variety. That was in 1917, and from 1920 on, we were in position to deliver certain quantities. At the present time this plant is on sale at the flower market of Paris and large quantities are sold at a high price, ten times as much as we ourselves had sold it.
In this account, H. Correvon refers to his first description of the rose, published in The Gardener’s Chronicle of December 9, 1922:
A few years ago a friend of mine, Dr. Roulet, found in a little village near Grandson, a very minute rose grown in pots in the windows. It was a minuscule shrub; five centimetres high, bushy, and covered with small roses not exceeding one and a half centimetres broad (just like a sixpenny piece). He told me about the plants and I went to see them; but just at that time the whole village of Mauborget had been burned, so we could not find a single plant. Local people stated that a woman in another village, Onnens, five miles away, had a similar plant. So we went there and my friend obtained a little growth of the rose, which he gave me. We increased it, and soon had hundreds of plants which I named Rosa Rouletii, after my friend. This is the most liliputian of all roses but where these good people got it from nobody can say.

[The article further relates how Ms. Fertig André Roulet (1881-1950) as the mayor of the neighbouring village of Fontaines, and that despite the report of Correvon, there is no evidence that the village of Mauborget burned at all in the years 1911-1922.]

Perhaps the most easily noted detail revealed about the China Roses by the similarity matrix though, was how many accessions had identical SSR profiles. The "C25 grp" on the dendrogram represents the China Rose cultivar Old Blush, with the group's oldest recorded date of introduction into Europe of around 1752 (Cairns (ed.), 2000), and the eight synonyms or sports found in this study: 'Climbing Old Blush', 'Green Rose', 'Single Pink', 'Rouletii' [all ex Antique Rose Emporium], 'Pompon de Paris' [ex Ralph Moore], 'Bengale d'Automne' [ex Vintage Gardens], 'Archduke Charles' [ex ARE], and an R. chinensis var. semperflorens [ex Flower Research Inst., Yunnan]. This large group of synonyms and sports still actively propagated and sold in the trade demonstrates how important 'Old Blush' continues to be, long after being used as a parent of importance in the breeding of modern roses.
....'Rouletii', which is a miniature with double pink recurrent blooms (Cairns (ed.), 2000), appears to be a dwarf sport of 'Old Blush'. 'Pompon de Paris' has also been described as appearing to be identical to at least one source of plants identified as 'Rouletii', and for this accessions sampled in this study, these two cultivars and 'Old Blush' share the same SSR profile. Only one source of 'Rouletii was sampled for this study though, so a future study combining field observation and genetics of multiple sources and their relationship to 'Old Blush' might be of interest to breeders, producers, and growers.

Editor: 'Rouletii' can also be long lived. in 1986 Mrs. Miskelly of Auckland was still growing a 'Rouletii' known to be at least 55 years old.
