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.
......'Archduke Charles' also looks reminiscent of 'Old Blush', and shares the characteristic pale pink blushing, changing to much darker pink flowers, but with more exaggerated colors and a higher petal count (Dickerson, 1992). 'Archduke Charles' has been referenced as a possible seedling of 'Old Blush', but the accession in this study had the same SSR profile as Old Blush, and would therefore be a sport.

In Queensland Hospitality, the first part of Sue and John Zwar’s account of their holiday among the heritage roses of Queensland (HRIA journal, Summer 2004). Sue noted a rose named “Rita Peterson” growing in the New Farm Park Rose Garden in Brisbane. She wrote, “…. I was particularly impressed with an Australian China called “Rita Peterson”, a large bush covered with soft red blooms.” We see above that ‘Editor” Stewart also noted a rose by that name in 1938: “I was amused, however, to see our old friend ‘General Gallieni’ labelled everywhere as “Rita Peterson”, evidently a name of local origin.” Present day Brisbane rosarians do not agree with ‘Editor’ Stewart so we would be very interested to know if the “Rita Peterson” grown today is the same rose ‘Editor’ Stewart saw in the 1930’s, and whether anyone can shed more light on the history of the rose grown under this name.

Seeking Rita Peterson. Following Editor Stewart’s article which was reprinted in the Winter Journal there was a question about the identity of “Rita Peterson" – we have some sleuths on the job. One of our members is a librarian at the State Library and she is directing some research into the matter. It seems that the “Rita Peterson” that T. A. Stewart describes is definitely not ‘General Gallieni’. The investigation continues. Jennie O’Brien Lutton

‘Archduke Charles’/’Archiduc Charles’ = Ancien – Chine – tons rouges, remontant… pétales extérieurs, pourpre cramoisi lavé de rose au centre, tendent de tourner au cramoisi uni, mais le soleil brûlant les fait virer à l’incarnat. De longue durée, bien pleine et fleurant la banane, elle s’évase en coupe, les larges pétales du pourtour enserrant des pétales plus petits, rose pâle ou blanc rosé vers le cœur. Bien remontant et peu épineux... Durant longtemps, aux Bermudes, il a été pris pour ‘Seven Sisters’. Liffay, France, avant 1837.
