....The Bermuda Rose Society logo features the rose 'Slater's Crimson China' as it is now known, previously called by its mystery name "Belfield"..... the Society has propagated it intensively and all new members receive a bush to care for.

p69. Gregg Lowery. "Belfield". when the American rosarian Richard Thomson encountered this rose at Belfield, he believed he had discovered the long-lost 'Slater's Crimson China'. Long familiar to Bermudians as the "Belfield" or "the Belfield rose", the rose has small deep red flowers with yellow stamens and only the occasional fleck of white. Compact and ever-blooming, it has a very ancient appearance.

'Slater's China' (R. chinensis var. semperflorens). The Bermuda samples were different from the other six samples tested, five of which were identical: four from San Jose, California, and one from the Botanical Garden of Lyon. Differing from all these was a sample from l'Hay-les-Roses, France.

Table 1 The main morphological characters, distribution information, and chromosome number of varieties of R. odorata and R. chinensis, with respective names taken from Hurst's (1941) descriptions
R. chinensis 'Yue yuehong'; 2n = 2x, 3x, 4x = 14, 21, 28; Double or semi-double; Variable [colour]; Widely cultivated elsewhere; Slater's Crimson China = R. chinensis var. semperflorens

The accession of R. chinensis var. semperflorens [ex Flower Research Inst., Yunnan] in this study was in the 'Old Blush' group based on the SSR data as well, so assuming correct collection and labeling, this example of the red variety of R. chinensis appears to be a flower color sport of 'Old Blush' or vice versa. It is also notable that this particular specimen is not identical to the specimen of 'Slater's Crimson China' (C29) [ex Ralph Moore] used in this study, though they are sometimes cross-referenced because these names have been used interchangeably at times in history (Dickerson, 1992).. In addition, these samples of R. chinensis var. semperflorens and 'Slater's Crimson China' were different ploidy levels: diploid and triploid, respectively. A rose that did prove to have the same profile as 'Slater's Crimson China' was the found rose 'Ferndale Red China' (C38) [ex Vintage Gardens], so it seems that rose has found its identity. However, there is more than one plant identified in the trade as 'Slater's Crimson China' (Piola, et al., 2002), so testing multiple sources could investigate the different clones in the trade, but would still not be able to say with certainty which were the original cultivar.

"[Bermuda] Belfield". ['Slater's Crimson China']. Ch. Rapid rebloom., Moderate fragrance. Habit [diagram] 2. Introducer & date. [Provenance: Knopf; Bermuda]. Much has been said about this rose and many are now willing to consider this the original 'Slater's Crimson China' introduced to Europe in the late 18th century; we count ourselves among them. Small, deep red flowers saturated with color, only slightly paler in the very center of the bloom, where the yellow stamens appear.
