I don't have 'Mme. Lauriol de Barny' in the garden and haven't seen it, at least not identified as such. I took a look at the newest page of photos of this variety on HMF, and, though I haven't made a careful comparison, right now I wouldn't swear that the rose I see in the photos isn't my 'Duc de Fitzjames'. My rose is a good tough variety with opulent blooms, coming easily from cuttings, has never reflowered later in the season, and gets some fungal disease after blooming, though not enough to do it any harm. Lanky in growth; thorny. I'm fond of it, mainly because of the very handsome blooms combined with the ability to flourish in quite poor conditions.
