HMF gives Vibert as the breeder of this rose and 1845 as the introduction date, but in his 1845 catalogue, Vibert doesn't indicate that he bred this rose. I suspect that William Paul, writing in 1848, was correct to say that the rose was introduced in 1845 'from Angers', however.

One likely possibility is that Vibert discovered this rose as a sport. I've seen a number of roses that are attributed to him that he didn't claim as coming from his "semis". He must have discovered and introduced any number of sports during his long career, but I don't think he tagged them in his catalogues as his creations. The 1845 catalogue's price of 3 1/2 francs does seem appropriate for an 1845 rose introduction.
