Recurrent-flowering roses frequently mutate to a climbing habit in which the first flush of flowers in spring is followed by a second flowering late in the growing season. The climbing mutants differ from the original cultivar in producing more nodes before the iflorescence is initiated, not by an increase in the length of internodes. They arise from a mutation that occurs within the transposon that disabled RoKSN and involves a reduction of 9-kbp transposon to a 1-kbp fragment of DNA (Iwata et al., 2012). This reduction results in a partial reversion to seasonal flowering. In the diploid climbing rose “Old Blush Cl.” the only form of RoKSN present is that with the 1-kbp fragment.

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.
'Climbing Old Blush' was already known to be a climbing sport of 'Old Blush'....

...Commercial nurseries offered plants of many varieties and types under this name between 1890 and 1900, Among them were: a vigorous climber with flowers and foliage identical with Old Blush, a climber with very pale pink flowers of Noisette type, and a trailer.

Blush China (Climbing form). Flower medium, 2 1/2 in., semi-double, deep rose, darker at base of petals, in clusters, ten to twelve. Calyx equals bud, not winged. Leaves pale green, shining, edges waved. Wood green, very large; red thorns. This is not the same as the 'Blush China', being a semi-climber, and differing in a few minor points. Miss Willmott figures it, page 79.
