Margaret Furness.  Random Notes About Chinas.  
I used to assume that Chinas didn’t sucker, until Viridiflora (Smith 1827) appeared some distance from where it had been removed.

... the ‘Green Rose’ or R. viridiflora, which Graham S. Thomas claimed originated as a mutation of R. chinensis in Charleston, South Carolina, in 1853 (but, according to Krussmann was already in cultivation ninety years earlier), is a rose known in China for centuries.

The China Rose Society has organised experts to collect, identify and preserve the cultivars scattered in home gardens around the countryside, and made a preliminary determination of eight rose centres in Huaiyin (Jiangsu Province), Laizhou (Shandong Province), Zhengzhou (Henan Province), etc. More than 50 old rose cultivars like Lv e were ex situ conserved and some old rose cultivars such as Ruan xiang hong, Jin fen lian, and Fen he xiang were successfully used for the improvement of new rose cultivars.

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.
.....the 'Green Rose' or 'Viridiflora' had been speculated to be another sport, and was also found to be genetically identical in several previous studies (Martin, et al., 2001; Scariot, et al., 2006).

p. 68: ...identical phenotypes were found within OGR cultivars for R. xcentifolia L. 'Rubra' and 'Crested Moss' for 'Kazanlik', 'Quatre Saisons Blanc Mousseux' and 'York and Lancaster', and for 'Old Blush' and 'Viridiflora'.

p. 71: Lastly, data confirmed the possibility that ʻViridifloraʼ is a sport of ʻOld Blushʼ (Beales et al., 1998).

‘Green Rose’ / Rosa chinensis viridiflora / ‘Rosa Monstrosa’ / R. viridiflora = Ancien – Chine – vert, remontant. Apprécié depuis longtemps des amateurs d’art floral, c’est un curieux rosier dont les fleurs troquent leurs pétales contre de longs sépales verts… Avant 1833. Peut-être un sport de ‘Old Blush’.
