'R. rouletii' rose Reviews & Comments

"‘Climbing Old Blush’ was already known to be a climbing sport of ‘Old Blush’,
and 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). The cultivar Single Pink was shown to be identical to ‘Old Blush’
in this study as well, supporting the hypothesis that it is a single flowered sport of ‘Old
36
Blush’ (Phillips and Rix, 1988), or visa versa. ‘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 the 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. "

Unfortunately, no mention of 'Oakington Ruby'.
One big ol' ball of mutations lol.

Earlier this summer I sowed a few open pollenated seeds from Rosa chinensis 'Minima', five germinated and I pricked out the seedlings in a 1.5LT pot. Four are the normal pale pink whilst one is much darker. The mother plant was right next to 'Baby Faurax', I wonder if they might have cross pollenated?

It could just be a random gene combination from being self pollinated. They are cute though.

Thanks HerbertG. The leaves are slightly darker than the others and when I've grown this rose from seed before the seedlings have been fairly consistent, all the same pale pink colour as 'Old Blush' and 'Pompom de Paris, climbing'. I'll give the pale seedlings away and grow the dark one on and see what it grows like.

It certainly could be a Baby Faurax pollination. Anything can happen. I'd grow it on and just observe if there are any other similarities.

Check if there are fringed stipules on the darker one, which would indicate Multiflora ancestry from 'Baby Faurax' pollen.

The Rose Annual 1973, Royal National Rose Society.
China Roses by Tess Allen.
p.34.
It was the botanist-nurseryman R. Sweet who gave the name Rosa lawranceana to the single form of the miniature China rose which was also known as the fairy rose. The current name is Rosa chinensis var. minima. Andrews states that the double form flowered for the first time in 1819 at Hammersmith Nursery. The double rose was introduced into France where it was known as the 'Bengal Pompon'. In Europe the miniature China roses appeared to have been extinguished by the slow test of time until Major Roulet, a surgeon in the Swiss Army, noticed pot plants of a double rosy-pink miniature China rose growing at Manborgel in Switzerland. The villagers told him that the rose. which had been grown in the area for a hundred years, originally came from France. The Swiss miniature rose was re-introduced into in 1922 as Rosa roulettii.
