The first [direct descendant of 'Rose Edouard'] is a Bréon seedling from 1820, most likely from hips originated from Reunion. The corresponding rose still grows in the ...rose gardens such as L'Haÿ and Sangerhausen, as R. x borboniana or 'Bourbon Jacques'. The rosebush, freely suckering, is very vigorous and sends its canes reaching upwards of two meters. The flowers are markedly paler pink than the 'Rose Edouard'. ...
The genetic fingerprints of the two candidate roses [plus 'Rose des Ile-Bourbon']...which are tetraploids, were compared with those of the 'Rose Edouard'. The DNA tests show in both cases an identity of 50% of the markers for each locus considered, which means at least two of the four alleles. Among these shared markers, there is often an 'Old Blush' allele and a 'Four Seasons' allele, from the grandparents....Our results provide evidence that the 'Rose Jacques' and 'Rose des Ile Bourbon' represent direct descendants of 'Rose Edouard'...

The fruit setting (development of hips) was very poor in the species Rosa borboniana even when selfed (22%). It did not set any fruit when crossed with Rosa damascena either as male or female parent. It was observed that when this species was crossed with the species Rosa centifolia no fruit was developed when used as male but success of fruit setting percentage was very low (4.28%) when used as female parent. This reflects that these two Rosa species had no compatibility with Rosaborbonica. However, a limited success in fruit setting (10%) was observed in the crosses Rosa borboniana x Rosa 'Gruss an Teplitz' and rosa 'Gruss an Teplitz' x Rosa borboniana....

‘Bourbon Rose/Rosa x bourboniana = Ce nom regroupe des hybrides sans doute issus d’un croisement de Rosa chinensis avec Rosa damascena semperflorens. Ecloses en solitaires ou en bouquets légers, leurs fleurs doubles ou semi-doubles, de 8cm de diamètre, déclinent la gamme des roses, rouges et pourpres. Certains de ces hybrides sont remontants. 1817.

The name Bourbon was given to the race because the first plant was a chance seedling found on the Île de Bourbon (Île de Réunion) in 1817, growing in close proximity to both its parents. It became known as 'Rose Edward' in the adjacent island of Mauritius. Seeds were sent to Paris and presumably the best one raised was called 'Le Rosier de l'Île Bourbon'... In its second generation it was named and distributed in France around 1823, reaching England about two years later.

L'Île de Bourbon Rose, said to have been imported from Mauritius to France, in 1822, by Mons Noisette [it flowered again in autumn] ... [According to the French botanist, Monsieur Breon, residents of the Isle of Bourbon bordered their properties with a double row of roses -- the common China Rose [presumbably 'Parson's Pink'] and the Red Four-Seasons [presumably the red 'Tous-les-Mois'] one day, a rose distinctly unlike these 2 was found in one of the hedges... In 1822, Breon sent plants to Monsieur Jacques, gardener at the Château de Neuilly, near Paris -- [Jacques] distributed them among the rose cultivators of France (whence the name often given to the Common Bourbon Rose of 'Bourbon Jacques'.) Mons Breon named it 'Rose de l'Île de Bourbon'; and is convinced that it is a hybrid from one of the above roses, and a native of the island...
Mons Jacques wrote he received the plants in October or November of 1819… Jacques sowed the seeds from 5 rose-hips… two of these bloomed in 1821… one had semi-double flowers of brilliant pink, and served that same year as a model for Redouté's picture, and was then propagated under the name 'Rosier de Bourbon'… It was introduced [to the US] in 1828, by the late Thomas Hibbert, whose name will always be associated in the memory of many with rose culture…Its arrival was much celebrated, and it was grown by practically everyone - and then it was removed from the gardens because it took up too much room. This rose gave a great quantity of seed, giving rise to many seedlings... In 1831, Mons Desprez, amateur from Yèbles... raised two plants from the original type...
