It is found that TMB [1,3,5-trimethyloxybenzene] originated from R. chinensis var. spontanea and is also known to have a sedative effect (Shoji et al., 2000).

Martyn Rix traces the history of botanists' documentation of this rose, starting with E.H. Wilson in Plantae Wilsonianae in 1914 through Flora of China. He discusses R. lucidissima Léveillé, which is included as a distinct species in Flora of China. Rix posits that R. lucidissima Léveillé is a form of R. chinensis f. spontanea in which all leaves have only three leaflets. Rix also chooses to assign the name R. chinensis f. spontanea rather than var. spontanea.
Propagation is best done by cuttings as seed often takes 3 years to germinate.

Rosa chinensis f spontanea Rehd. & E.H. Wils./ Rosa indica Hemsl. Non L. nec Lour. /’Henry’s Crimson China’ des anglais. Découvert en 1885, par A.Henry en Chine, Yichang… existe en d’autres parties de la Chine et naturalisé en Inde. Sans doute pas cultivé en Europe. 1m à 2m de hauteur. C’est la forme sauvage… buisson à fleurs simples, à floraison unique en juin, rouge foncé ou roses, et placées solitaires. Bien qu’on ne le cultive pas, il est impossible de la passer sous silence, à cause de sa descendance. Sans lui, les Rosa x odorata, des hybrides des jardins chinois et aussi un grand nombre de ceux de nos jardins, vraisemblablement, n’auraient jamais existé!

[From "Notes on the Origin and Evolution of our Garden Roses" by C. C. Hurst]

In its characters it [Slater's Crimson China¨is very near to Henry's Crimson China, collected in 1885 in the San-yu-tung Glen near Ichang in the Province of Hupeh, Central China, which is generally considered to be the wild species and original ancestor of the China Roses. Slater's Crimson China differs from the wild species in its dwarf habit, semi-double flowers, and perennial flowering, all of which are Mendelian characters, the genes for the first and last characters being closely linked in the same chromosome.
